The net force on the top charge due to the other two charges is zero, and the charge will remain in equilibrium.

We can use Coulomb's law to calculate the force exerted by one charge on another. Coulomb's law states that the magnitude of the electrostatic force between two point charges is proportional to the product of their charges and inversely proportional to the square of the distance between them.

Mathematically, it can be expressed as:

F = (kq1q2)/r^2

where;

In this case, we have three charges of equal magnitude q placed at the vertices of an equilateral triangle of side length 1. We can calculate the distance between any two charges using the geometry of the equilateral triangle. The distance between any two adjacent charges is 1, and the distance between any two opposite charges is √3.

Let's consider the force exerted on one of the charges, say the one at the top of the triangle, due to the other two charges at the bottom left and bottom right vertices. The distance between the top and bottom left charges is 1, and the distance between the top and bottom right charges is also 1.

Therefore, the magnitude of the force exerted by the bottom left charge on the top charge is:

F1 = (kqq)/1^2 = k*q^2

Similarly, the magnitude of the force exerted by the bottom right charge on the top charge is also k*q^2. Since the two forces are acting in opposite directions along the same line, we can simply subtract them to find the net force:

F_net = F1 - F2 = kq^2 - kq^2

F_net = 0

Therefore, the net force on the top charge due to the other two charges is zero, and the charge will remain in equilibrium.

Answer:

a) - 8 m/s₂

b) 100 meters

Explanation:

The equation relating final velocity, initial velocity, acceleration and time to reach final velocity from initial velocity is given by

v = u + at

where
v = final velocity
u = initial velocity
a = acceleration
t = time taken

Here the dragster starts at 40m/s and comes to a total stop after 5 seconds

Therefore v = 0, u = 40 m/s and t = 5 seconds

Plugging this in:
0 = 40 - a · 5

0 = 40 + 5a

5a = - 40

a = -40/5 = -8 m/s²

The negative sign indicates it is deceleration rather than acceleration

The distance traveled is given by the formula
d = vₐ x t
where
d = distance traveled
vₐ = average velocity
t = time taken

Since acceleration(or, in this case deceleration) is uniform
average velocity

vₐ = 1/2 x (u + v) = 1/2 x (0 + 40) = 20 m/s

d = 20 x 5 = 100 meters

Answer:

Explanation:

v=u+at

v= final velocity

u= initial velocity

a=acceleration

t= time

the final velocity=0 as it became to rest

v=u+at

0= 40 +(-a)*5

-40=-a*5

a=8

∴ the negative acceleration (deceleration) of the car is 8ms^-2

s=ut + 1/2at^2

s= 40*5 - 1/2*8*25

s= 200- 100

s=100m

Therefore, the car travels 100m after the acceleration.

Answer:

Blue

Explanation:

The frequency of light can be calculated using the formula:

frequency = speed of light / wavelength

The speed of light is a constant, approximately 3.00 x 10^8 m/s.

Converting the wavelength of light from nanometers (nm) to meters:

480 nm = 480 x 10^-9 m

Now we can calculate the frequency:

frequency = (3.00 x 10^8 m/s) / (480 x 10^-9 m) = 6.25 x 10^14 Hz

The color of light with a wavelength of 480 nm is blue.

Since the wavelength of the light in this question is 480 nm, Blue color falls within the range of the blue color. Therefore, light with a wavelength of 480 nm appears blue to the human eye.

The acceleration of Procyon A will be greater than the acceleration of Procyon B because it is the more massive object in the binary system.

Acceleration is the rate of change of an object's velocity over time. It is often represented as a vector and is measured in meters per second squared (m/s2). Acceleration is the result of a physical force, such as gravity, friction, or a push or pull.  In physics, acceleration is a fundamental concept, as it is used to calculate the motion of objects. It can also be used to calculate forces, such as the force of a spring or the force of a car’s brakes.

Since the two stars are orbiting each other, the more massive object will experience a greater gravitational pull from the other, resulting in a greater acceleration. This is due to Newton's law of universal gravitation, which states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Therefore, Procyon A will experience a greater acceleration due to its greater mass.

The required number of turns in the secondary coil is 800 and the currents in the primary and secondary coils are 2.5 A and 5 A respectively.

Electric current is the flow of electric charge through a material. It is typically expressed in units of amperes (A), which represent the rate at which charge flows through a conductor.

First, let's calculate the power in the secondary coil

Power in secondary coil = Power in primary coil x Efficiency

= 1.1 kW x 1.0

= 1.1 kW

Since the voltage is doubled in the secondary coil, the current must be halved to maintain the same power,

Current in secondary coil = Power in secondary coil / Voltage in the secondary coil

= 1.1 kW / 220 V

= 5 A

The voltage ratio formula to find the number of turns in the secondary coil,

Voltage ratio = Voltage in the secondary coil / Voltage in the primary coil

= 220 V / 110 V

= 2

(number of turns in the secondary coil) / 400 = 2

Number of turns in secondary coil = 800

The current ratio formula to find the current in the primary coil,

Current ratio = (number of turns in the primary coil) / (number of turns in the secondary coil)

(Current in the primary coil) / 5 A = 400 / 800

Current in primary coil = 2.5 A

So the number of turns in the secondary coil is 800 and the currents in the primary and secondary coils are 2.5 A and 5 A respectively.

Explanation:

Let's first find out how much time it takes for Harry and Kate to meet each other:

We can use the formula: distance = speed × time

Let's assume they meet after t minutes.

Distance covered by Harry in t minutes = 40t

Distance covered by Kate in t minutes = 60t

Total distance covered = 40t + 60t = 100t

Since they started from a distance of 2500 meters, the total distance covered is also equal to 2500 meters.

Therefore, we have the equation: 100t = 2500

Solving for t, we get t = 25 minutes.

Now, let's find the distance covered by the dog in 25 minutes.

The dog covers a distance of 120 meters per minute, so in 25 minutes, the dog would cover a distance of:

120 × 25 = 3000 meters

Therefore, the dog would have travelled a distance of 3000 meters when Harry and Kate meet each other.

The requried width of the lake is 500 meters.

If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.

Here,
Let's call the width of the lake "x". We can see from the diagram that the length of the line connecting the two ends of the lake is the hypotenuse of a right triangle with one leg equal to x/2 (half of the width of the lake) and the other leg equal to 50 meters. The angle between the two legs of the triangle is 30 degrees.

Using the trigonometric function cosine, we can write:

cos(30°) = adjacent/hypotenuse

cos(30°) = (x/2)/√(x^2/4 + 50^2)

x = 500 meters

The deceleration of the body is -2 [tex]m/s^2[/tex] (note the negative sign indicating that it is decelerating or slowing down).

Acceleration is the rate at which velocity changes over time, both in terms of speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down.

a) To find the deceleration of the body, we can use the formula:

Acceleration = (final velocity - initial velocity) / time

Since the body comes to rest after decelerating uniformly, the final velocity is 0.

The initial velocity is the speed at which the body was moving before it started decelerating, which is 10 m/s. The time taken to decelerate is 5 seconds.

Substituting these values in the above formula, we get:

Acceleration = (0 - 10) / 5

Acceleration = -2 m/s^2

Therefore, the deceleration of the body is 2 m/s^2 (note the negative sign indicating that it is decelerating or slowing down).

b) The total distance travelled by the body can be calculated as the sum of the distance covered during the constant speed phase and the distance covered during the deceleration phase.

During the constant speed phase, the distance covered is:

Distance = speed x time

Distance = 10 m/s x 10 s

Distance = 100 m

During the deceleration phase, the average speed can be calculated as the average of the initial and final speeds:

Average speed = (initial velocity + final velocity) / 2

Average speed = (10 m/s + 0) / 2

Average speed = 5 m/s

The distance covered during deceleration can be calculated using the formula:

Distance = average speed x time - (1/2) x acceleration x time^2

Substituting the values, we get:

Distance = 5 m/s x 5 s - (1/2) x [tex](-2 m/s^2)[/tex] x [tex](5 s)^2[/tex]

Distance = 25 m + 25 m

Distance = 50 m

Therefore, the total distance travelled by the body is:

Total distance = distance during constant speed + distance during deceleration

Total distance = 100 m + 50 m

Total distance = 150 m

Hence, the body travels a total distance of 150 meters.

Thus, this is the answer of the given scenario.

Explanation:

The work done by the first person in lifting the weight to a height H is given by:

W = F × d = 200 × H

The power output P of the first person is then given by:

P = W / T = (200 × H) / T

To lift the same weight to a height of 2H in time T/2, the second person would have to do twice the work done by the first person, since work done is equal to force times distance. Therefore, the work done by the second person is given by:

W = 2 × (200 × 2H) = 800H

The power output of the second person is then given by:

P' = W / (T/2) = (800H) / (T/2) = (800H × 2) / T = 1600H / T

Comparing the power output of the first person (P) and the second person (P'), we have:

P' / P = (1600H / T) / (200H / T) = 8

Therefore, the power output of the second person is 8 times the power output of the first person. So, the correct option is (3) 2P.

Explanation:

The period of a wave is the time it takes for one complete cycle of the wave to occur, and is usually measured in seconds.

The particle's maximum position coordinate is 787.5 m.

Given that the acceleration is constant, we can use the following kinematic equations:

where

We are given that the particle starts from the origin with an initial velocity of v0 = -14 m/s and accelerates uniformly, as shown in Fig. 2.

We can use the acceleration-time graph to find the acceleration value. Looking at Fig. 2, we can see that the acceleration is 7 m/s^2.

a = 7 m/s^2

v0 = -14 m/s

Using Equation 1, we can find the particle's velocity at any time t.

v = v0 + at

For 0 < t < 15 s, the particle's velocity will be:

v = -14 + 7t

Using Equation 2, we can find the particle's position at any time t.

x = x0 + v0t + 1/2at^2

Since the particle starts from the origin (x0 = 0), we can simplify Equation 2 to:

x = v0t + 1/2at^2

For 0 < t < 15 s, the particle's position will be:

x = -14t + 1/2(7)t^2

Now, let's plot the v-t and x-t curves.

v-t Curve:

Therefore, the particle's maximum velocity is 91 m/s.

The ice can be kept from melting by applying either more or less pressure, and sprinkles of salt will have no effect , none of these things will make any difference.

Option D is correct.

When the temperature on one wall is lowered below the freezing temperature or fusion point, a cooling effect is thereby initiated, resulting in the formation.

If the temperature is above 0°C, then increased pressure is required to keep the ice from melting. A freezing or solidification process may occur in a liquid at a uniform temperature, either above or at the freezing temperature or fusion point. This is because the temperature at which water molecules begin to move more quickly in order to melt decreases as pressure increases. The ice can remain frozen at temperatures above 0°C because the melting temperature is decreased when the pressure is raised.

On the other hand, ice can be frozen at lower temperatures with reduced pressure. This is because lower pressure causes the temperature at which water molecules begin to move faster, which is necessary for them to melt, to rise. The ice can remain frozen at temperatures below 0°C because the melting temperature is raised when the pressure is reduced.

Adding salt to ice will not affect its ability to remain frozen at higher temperatures. Instead, salt is utilized to lower water's freezing point, causing the ice to melt at lower temperatures. This is due to the fact that salt dissolves in water, resulting in a solution with a lower freezing point than just water.
