Gravity works on tiles.

<h2>Further Explanation </h2>

Gravity or gravity is the attraction that occurs between all particles that have mass in the universe. Sun's gravity causes celestial bodies to be in their respective orbits around the sun. Modern physics describes gravity using Einstein's Theory of General Relativity, but Newton's simpler universal law of gravity is a fairly accurate estimate in many cases.

For example, the earth which has a very large mass produces a very large gravitational force to attract objects around it, including living things, and objects that exist on earth. This gravitational force also attracts objects in space, such as the moon, meteors, and other celestial bodies, including man-made satellites.

Kinetic energy or motion energy (also called kinetic energy) is the energy possessed by an object because of its motion.

The kinetic energy of an object is defined as the effort needed to move an object with a certain mass from rest to a certain speed.

The kinetic energy of an object is equal to the amount of effort required to express its speed and rotation, starting from the others.

Modern research in the theory of gravity began with the work of Galileo Galilei in the late 16th century and early 17th century. With the results of his experiments dropping the ball from the Tower of Pisa, and then also measuring the ball sliding through the slope, Galileo showed that the magnitude of gravitational acceleration was the same for all objects. This is a big advance from Aristotle's earlier belief that heavier objects have greater gravitational acceleration.

Readme [11.4K]

Answer:

4.7 x 10³ rad / s

Explanation:

During the time light goes and comes back , one slot is replaced by next slot while rotating  before the light source

Time taken by light to travel a distance of 2 x 500 m is

= (2 x 500) / 3 x 10⁸

= 3.333 x 10⁻⁶ s .

In this time period, two consecutive slots come before the source of light one after another by rotation. There are 400 slots so time taken to make one rotation

= 3.333 x 10⁻⁶ x 400

= 13.33 x 10⁻⁴ s

This is the time period so

T = 13.33 X 10⁻⁴

Angular speed

= 2π / T

= \frac{2\times3.14}{13.33\times10^{-4}}

4.7 x 10³ rad / s

GalinKa [24]

Answer:N=0

Explanation:

Given

m_1=9.6 kg

m_2=0.8 kg

both blocks experiencing free fall so net weight of block during free fall is zero thus there is no normal reaction between them.

State the condition under which a satellite would move with escape velocity
elixir [45]
When the launch velocity is a bit less than the escape velocity, the satellite with time will find itself back to earth and when the speed is far beyond the escape velocity, the satellite with time, be lost in space.

The velocity of escape from the less massive Moon is about 2.4 km per second at its surface. ... A planet (or satellite) cannot long retain an atmosphere if the planet's escape velocity is low enough to be near the average velocity of the gas molecules making up the atmosphere.
