A gravitational force between objects depends on two things- their masses and the distance between them. So the greater the mass and the less distance there is, the more gravitational force and is the mass is less and the distance is great the gravitational force is weak
Answer:
All fraction of kinectic energy is lost to barrel of a spring gun of mass 1.8 kg
Explanation:
A ball of mass 0.50 kg is fired with velocity 160 m/s ...
The kinetic energy is given by 1/2mv²
Kinectic energy of the ball = 1/2 *0.5*160²
Kinectic energy = 1/4 *25600
Kinectic energy = 6400 joules.
If no energy is lost to fiction, and the ball sticks to a barrel of a spring gun of mass 1.8 kg with initial velocity zero, all kinetic energy is lost to the barrel of a spring gun of mass 1.8 kg.

Answer:
kinetic energy does not change
Explanation:
you can use the formula for the kinetic energy of the electron and for the radius of the trajectory of an electron in a uniform magnetic field:
me: mass of the electron
B: magnetic field
q: charge of the electron
r: radius
By doing v the subject of the formula and replace it in the expression for the kinetic energy you obtain:
as youcan see, all parameters r, q, B and me are constant.
hence, the kinetic energy does not change
Answer:
Sound travels in air as a series of compressions and rarefactions. When an object vibrates it will move back and forth. As it moves forth, it pushes adjacent air particles. ... This is a compression: an area of high pressure that moves along the direction of the sound wave.
Explanation:
adjacent is the answer
