  • Moon's Orbit <u>(C). Earth</u>
  • Tides on Earth <u>(B). Moon</u>
  • Earth's Orbit <u>(A). Sun</u>

<h3>Introduction</h3>

Hi ! I will help you to explain about gravity. Gravity is one part of the force that will pull two or more objects that interact with each other to the center of their weight. Because it is a force, and interacts with mass, the gravitational force can also cause an acceleration called gravitational acceleration.The characteristic of gravity are:

  1. Mass cannot be affected by gravitational acceleration, because mass itself has formed gravitational interactions.
  2. The weight of an object is something that can be affected by the acceleration of gravity, because weight is a derived quantity in Newtons (N)
  3. The lighter object will fall to the heavier object because the center of mass will be closer to the object with greater mass.

<h2>Explanation</h2>

Let's go into more detail about my answer!

<h3>Moon's Orbit</h3>

The moon undergoes two motions, orbiting the Earth and orbiting the sun together. So, here the gravitational force from the Earth can be said to have more effect on the Moon. Without the influence of Earth's gravity, the moon will orbit the sun itself by the interaction of its own gravitational force with the sun.

<h3>Tides on Earth</h3>

The tides are caused by the Moon's gravitational force. Remember ! The Earth's gravitational force always points downwards to make a constant (so that water does not spill when it is hit by the Moon's gravity). The Moon's gravitational force also depends on how close it is to Earth.

<h3>Earth's Orbit</h3>

Like the Moon, the Earth orbits the sun. However, the sun is now creating a gravitational field. Not only for Earth, but for all objects in the solar system.

A cyclist travels 21 km in 90 minutes. Calculate, in m s–1 , the speed of the cyclist.
sasho [114]

Answer:

35/9 m/s

Explanation:

21 km = 21000 m

90 min = 90*60 s = 5400 s

21000/5400 = 35/9 m/s

What is the minimum height of a planar mirror placed in a vertical plane 2m distant that will permit a person 2m tall to see the
Taya2010 [7]

Answer:

Height of mirror will be 1 m for complete image of person

Explanation:

We have given distance of person from plane mirror d = 2 m

And height of person = 2 m

We have to find the height of plane mirror which given full image of person

Height of mirror will be equal to half of height of person

So height of mirror =\frac{height\ of\ person}{2}=\frac{2}{2}=1m

So height of mirror will be 1 m for complete image of person

Clearly, Atwood’s machine has a lot of systematic error that would not be present if we were to simplify the experiment. What is
Sphinxa [80]

Answer:

Better Equilibrium Maintenance for better accuracy...

Explanation:

In the Galileo's experiment, there is no utilization of two equal masses at a time. However, as we can see in a Atwood Machine, there are two equal masses involved that make the whole system to be in a state of equilibrium and ultimately the better measurements of acceleration due to gravity.

RUDIKE [14]
The answer is A)100m : 0m
The pool is 50m long
so she swam from the two ends of the pool two times
so in total she swam 50x2 m which is 100m
and she she displaced no meters because she ended in the same point as where she started

Turning a corner at a typical large intersection in a city means driving your car through a circular arc with a radius of about
Naddik [55]

Answer:

9.89 m/s.

Explanation:

Given that,

The radius of the circular arc, r = 25 m

The acceleration of the vehicle is 0.40 times the free-fall acceleration i.e.,a = 0.4(9.8) = 3.92 m/s²

Let v is the maximum speed at which you should drive through this turn. It can be solved as follows :

a=\dfrac{v^2}{r}\\\\v=\sqrt{ar} \\\\v=\sqrt{3.92\times 25} \\\\=9.89 m/s

So, the maximum speed of the car should be 9.89 m/s.
