A-3 Ω
B-6 Ω
C-9 Ω
D-13.5 Ω

As we go down the earth, we are moving towards the centre of the earth therefore the distance between us and center of the earth reduces and hence there is reduction in force acting on us by earth i.e gravity.

Explanation:

A practical machine is a simple machine that losses energy and have parts that have weights, friction and it causes some loss of work done.

The answer will be pressure.

Pressure is force per unit area.

It will be unbalanced and at terminal velocity

Explanation:

answer 689910

M x G x H

mass = 77

G= 9.8

Meter = 915 this is the height

77 x 9.8= 754.6

754.6 X 915 = 689910 J

Dean Potter is known for slacklining across a 915-metter deep ravine in Yosemite National Park with no safety gear. If his mass is 77 kg then he has the potential energy of  691163.55 Joules

As total mechanical energy is the sum of all the kinetic as well as potential energy stored in the system.

ME = KE + PE

As given in the problem Dean Potter is known for slacklining across a 915-meter deep ravine in Yosemite National Park with no safety gear. If his mass is 77 kg,

m =77 kg

h = 915 m

the total potential energy of the dean potter can be calculated withe the help of the formula of the potential energy

PE = mgh

PE = 77*9.81*915

PE = 691163.55 Joules

Thus, he would have the potential energy of  691163.55 Joules

Answer:

Here,

density (d) = 1000 kg/m^3

gravity (g) = 10 m/ s^2

height (h) = 2m

Now,

liquid pressure = hdg

=2 x 1000 x 10

=20000 N/m^2

Thus, the liquid pressure is 20000 N/m^2

Explanation:

Area=side^2=4^2=16cm^2=0.0016m^2

[tex]\\ \sf\longmapsto Pressure=\dfrac{Force}{Area}[/tex]

[tex]\\ \sf\longmapsto Pressure=\dfrac{144}{0.0016}[/tex]

[tex]\\ \sf\longmapsto Pressure=90000Pa[/tex]

This question can simply be solved by the use of the basic formula of pressure.

The magnitude of pressure applied on the surface is "90000 Pa" (OR) "90 KPa".

The pressure is defined as the force applied per unit area in the normal direction. The pressure applied on a surface can be given by the following formula:

[tex]Pressure=\frac{Force}{Area}\\\\Pressure=\frac{144\ N}{(0.04\ m)^2}[/tex]

where,

Area of Square Surface = Side² = (0.04 m)²

Therefore,

Pressure = 90000 Pa = 90 KPa

Answer: acceleration will slow down.

Explanation: Since mass is inversely proportional to acceleration, if you increase the mass at a given force the rate of acceleration slows.

Answer:

3 cm

Explanation:

I think the question have some error because if height = 2 m = 200cm.

Volume of box = l * b * h

V = 30 cm³

b = 5 cm

h = 2 cm

l = ?

V = l * b * h

30 cm³ = l * 5 * 2

l = 30 / 10

l = 3 cm

Answer:

Transverse waves

Explanation:

Light moves in waves. Light waves are different from sound waves in that light travels in transverse waves (as opposed to longitudinal, which is how sound waves travel). A light wave that travels in a direction is called a light ray.

The light waves travel as Transverse waves. Therefore, option (1) is correct.

Transverse waves can be defined as waves that usually oscillate along paths that are perpendicular to the direction in which the wave is traveling. Examples of transverse waves involve the vibration of the guitar, electromagnetic waves, water surface ripples, primary waves of the earthquake, and seismic S waves.

Particles of matter in a transverse wave, oscillate up and down about their mean location rather than follow the path of the transmission of the wave.

A transverse wave can be described as every particle of the medium traveling around its mean position in an opposite direction of the propagating direction of the wave.

Transverse waves can be produced in solids and on the surface of liquids. Transverse waves are not possible to create in liquids or gases. Therefore, electromagnetic waves or light waves travel as Transverse waves.

Answer:

use the formula of slope=(x₂-x₁)/(y₂-y₁)

Explanation:

The slope of the bicycle's position versus time graph 5 s after it starts to assume constant velocity motion would be 7 meters/second.

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.

velocity slope =change in the position of the object /change in time

As given in the problem a bicycle starts at 50 m from an intersection. ten seconds later the bicycle is 85 m from the same intersection,

change in the position of the bicycle = 85-50

                                                              = 35 meters

change in the time = 10 -5 seconds

                                = 5 seconds

slope =  35 meters/5 seconds

         = 7 meters/second

Thus, the slope of the bicycle's position versus the time graph would be 7 meters/second.

Answer:

the positive and negative signs are used to show different directions of acceleration and velocity

Explanation:

for example, if a car was moving forward, you would usually express it with a positive sign. If the car started moving backwards, you would show that backwards motion with a negative sign.

the lionfish, a longstanding showstopper in home aquariums, is a flourishing invasive species in U.S. Southeast and Caribbean coastal waters. This invasive species has the potential to harm reef ecosystems because it is a top predator that competes for food and space with overfished native stocks such as snapper and grouper. Scientists fear that lionfish will also kill off helpful species such as algae-eating parrotfish, allowing seaweed to overtake the reefs. In the U.S., the lionfish population is continuing to grow and increase its range. This is largely because lionfish have no known predators and reproduce all year long; a mature female releases roughly two million eggs a year.

Answer: y = 2.33

Explanation:

Given expression

15 - 3y = 8

Subtract 15 on both sides

15 - 3y - 15 = 8 - 15

-3y = -7

Divide -3 on both sides

-3y / -3 = -7 / -3

[tex]\boxed{y=2.33}[/tex]

"A racquet can be a maximum of 29 inches long while the hitting surface (the head) cannot be more than 15.5 inches in length and 11.5 inches wide."

Distance = 10 miles

Displacement = zero

The coach must be fired and disciplined.

Explanation:

[tex]\text{Velocity is defined as the average displacement per unit time.}[/tex]

[tex]\text{Since the car is moving at a steady velocity, the velocity does not change over time, it shows a horizontal line on the }v-t\text{ graph}[/tex]

[tex]\text{Therefore, only option 2,5,8 matches this requirement.}[/tex]

[tex]\text{Since the car is moving to the right, which is defined as the positive direction in this question, the velocity (}v\text{) is also positive.}[/tex]

[tex]\text{Therefore, only option 5 is correct.}[/tex]

The graph marked with number [5] is the correct graph.

We have a Car.

We have to select the graph which shows that the car is moving toward the right (away from the origin) at a steady (constant) velocity.

The acceleration of the body at constant velocity is 0.

According to the question -

For constant velocity, the acceleration of the car will be zero. Now, if we plot the velocity - time graph for this motion considering that the car is moving away from the origin, then the graph marked with number [5] will be the correct choice since the velocity is constant (say v) throughout the time and the motion is along right of origin.

Hence, the graph marked with number [5] is the correct graph.
