Answer -

1. Since the circuit is connected in series, the current in the circuit will be 0 if all the components of the circuit are not turned on. This is because of the single path that a series circuit has. So here, when only 4 lamps are turned on, the current in the circuit will be 0.

2. In this case as well, the current passing through the series circuit will be 0 as the heater which is connected to the circuit through series connection is not switched on.

3. If all the components of the series circuit is turned on,

Equivalent Resistance,

Rn = R1 + R2 + R3 + R4 + R5 + R6 + R7

Rn = 10Ω + 240Ω + 240Ω + 240Ω + 240Ω + 240Ω + 240Ω

∴ Rn = 1450Ω.

Then, current flowing through the circuit will be V/Rn.

I = V/Rn

I = 120V / 1450Ω

I = 0.08275 A

I ≈ 0.083.

The magnitude of the charge on each sphere is 1.51 x 10^-7 C.

The magnitude of the charge on each sphere can be calculated using Coulomb's law:

F = k * q1 * q2 / r^2

where F is the force of repulsion, k is Coulomb's constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the magnitudes of the charges on the spheres, and r is the separation distance between the spheres.

Rearranging the equation to solve for the charge:

q = sqrt(F * r^2 / k)

Substituting the given values:

The second place finisher is 39.6 m behind the winner in the race when the winner crosses the finishing line.

In the 100m race, the time for winner is 10.7s and the time for second finisher is 12.1s.

Because the velocity is constant,

Now, we know,

Velocity = Distance/Time

Velocity of winner = 100/10.7

Velocity of winner = 9.34 m/s.

Velocity of the person at second place finisher = 100/12.1

Velocity of the person at second place finisher = 8.26 m/s.

Now, the difference in time period is,

Time difference = 12.1-10.7

Time difference = 1.4 s.

Now, the distance between the runner is given by,

Distance = Velocity of second finisher x time difference

Distance = 8.26 x 1.4

The ball is thrown in a horizontal direction from the roof of a building with an initial speed of 20 m/s. The ball strikes the ground 120 m from the base of the building. The height of the building is 180m.

The horizontal distance the ball travels before touching the ground, x= 120m. The initial speed with which the ball is thrown is u=20 m/s. So the time is taken by the ball to reach the ground, t= x/u =120/20 =6 secs.

Now, t=6 secs is the time taken by the ball to reach the ground. So the height of the building is given by the equation,  h= ut+1/2gt², where u is the initial speed in the vertical direction and g is the acceleration due to gravity and its value is g= 10m/s². The initial speed in the vertical direction is 0m/s. So, h= 1/2gt² , =1/2×10×6×6 =180m.

Benzaldehyde is not soluble in water because it is a non-polar molecule and water is a polar solvent.

Non-polar substances tend to dissolve in other non-polar substances, while polar substances dissolve in polar solvents. This is due to the fact that the polar water molecules form hydrogen bonds with each other, and the non-polar benzaldehyde molecule is unable to interact with these hydrogen bonds. As a result, benzaldehyde remains separate from the water molecules and does not dissolve in water. A non-polar substance is a chemical substance that does not have a charged distribution of electrons, meaning it does not have distinct positive and negative regions. These substances have a uniform distribution of electrons, resulting in a symmetrical molecule that does not have any polar bonds.

If thermal energy is added to 150 g of water at a rate of 55 J/s for 2.5 minutes, the temperature of the water will increase by 6.58°C, as calculated using the equation for specific heat capacity.

To determine the increase in temperature of 150 g of water when thermal energy is added at a rate of 55 J/s for 2.5 minutes, we need to calculate the amount of heat energy added to the water and use this to determine the increase in temperature.

The amount of heat energy added to the water can be calculated as follows:

Q = 55 J/s * 2.5 min * 60 s/min = 6675 J

Next, we can use the equation for specific heat capacity to determine the increase in temperature of the water:

ΔT = Q / (mass * specific heat capacity)

where ΔT is the increase in temperature, Q is the heat energy added, mass is the mass of water (150 g), and specific heat capacity is the amount of heat energy required to raise the temperature of 1 g of water by 1°C (usually around 4.18 J/g°C).

Substituting in the values, we have:

ΔT = 6675 J / (150 g * 4.18 J/g°C) = 6.58°C

Answer:

The reason why you get the same answer when you enter cos(30°) and cos(-30°) into your calculator is because cosine is a periodic function, which means that the same value is repeated after a certain interval. In the case of cosine, the interval is always 360°, so cos(30°) and cos(-30°) are equivalent because they are both equal to 30° away from 0°. Therefore, they both have the same value, which is 0.5.

The electric field strength is 0.046 C/m2, or 0.046 x 10-3 C/m2, or 0.046 mC/m2, at a distance of 46 mm (to one place after the decimal).

Calculate the electric field strength (E) at a distance of 46 mm using the formula

E=V/d, where V is the voltage and d is the distance.

E = V/d = (46 mm)/(1000 mm)

E = 0.046 V/m

Convert this electric field strength to milli-coulombs per square meter (10-3 c/m2) using the formula E=q/A, where q is the charge and A is the area.

We can assume that the area is 1 m2, and q is the electric field strength (0.046 V/m) multiplied by one coulomb, which is 1 C.

Therefore, q = (0.046 V/m) x (1C) = 0.046 C.

Calculate the electric field strength using the formula E = q/A.

E = q/A = (0.046 C)/(1 m2) = 0.046 C/m2

Convert the electric field strength to milli-coulombs per square meter (10-3 c/m2).

The electric field strength at a distance of 46 mm is 0.046 C/m2, which is equivalent to 0.046 x 10-3 C/m2, or 0.046 mC/m2 (to one place after the decimal).

The car travel 740m in the first 42 s after the light changes to green

To calculate the distance traveled by the car in the first 42 seconds after the light turns green, we need to consider two stages of motion: acceleration and constant velocity.

1. During the acceleration phase, the car's speed increases linearly with time, so we can use the equation:

v = v0 + at

where v is the final speed, v0 is the initial speed (0 m/s in this case), a is the acceleration (2.0 m/s^2), and t is the time elapsed. To find the time when the car reaches a speed of 20 m/s, we can solve for t:

t = (v - v0) / a = (20 m/s - 0 m/s) / 2.0 m/s^2 = 10 s

So, the car is accelerating for the first 10 seconds.

2. During the acceleration phase, the car's position changes according to the equation:

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

where x is the final position, x0 is the initial position (0 m), and t is the time elapsed. We can use this equation to find the distance traveled by the car during the first 10 seconds of acceleration:

x = 0 m + 0 m/s * 10 s + (1/2) * 2.0 m/s^2 * 10 s^2 = 100 m

3. During the constant velocity phase, the car's position changes according to the equation:

x = x0 + v0t + vt

where x is the final position, x0 is the initial position (the position at the end of the acceleration phase, which was 100 m), v0 is the initial velocity (20 m/s), and v is the constant velocity (20 m/s). To find the distance traveled by the car during the first 42 seconds (10 seconds of acceleration and 32 seconds of constant velocity), we can use this equation:

x = 100 m + 20 m/s * 32 s = 100 m + 640 m = 740 m

So, the car travels a total distance of 740 m in the first 42 seconds after the light turns green.
