Gravity works on tiles.
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.

Answer:
Scenario 1 will cause the sound of the drumstick hitting the metal bar to reach your ears in the least amount of time.
Explanation:
The sound wave will travel faster in the metal bar than through the air because the speed of sound waves in solids is faster than it is in gases.

Answer: B)
A hollow double concave lens acts as a diverging lens. When it is filled with a medium of higher refractive index than the surrounding, its diverging power increases.
So if the lens is:
A) Filled with air (n=1) and immersed in water (n=1.33) - Incorrect, air has lower refractive index than water
B) Filled with water (n=1.33) and immersed in CS2 (n=1.6) - Correct, water has lower refractive index than CS2
C) Filled with air (n=1) and immersed in CS2 (n=1.6) - Incorrect, air has lower refractive index than CS2
D) Filled with CS2 (n=1.6) and immersed in water (n=1.33) - Incorrect, CS2 has higher refractive index than water
Therefore, the lens will act as a diverging lens when filled with water and immersed in CS2, which is option B.
The key is that the material inside the lens must have a lower refractive index than the surrounding medium to increase the diverging power of the concave lens.
Explanation:
b. They create large rifts in the earth.
c. They occur along the edges of the tectonic plates.
d. They alter the topography of the surface of the earth. Please help
Answer:
B) 5
Explanation:
Mechanical advantage = D/W
= 10/2
= 5.
It has no unit because the inches in the length and width will cancel out.
