In our solar system, terrestrial planets are separated from the gas giants by the asteroid belt. The asteroid belt is a region in the solar system between Mars and Jupiter where asteroids are located. Gas giants do not have a solid surface and possible a small rocky core. The gas giants are Jupiter, Saturn, Uranus and Neptune. The first four planets, Mercury, Venus, Earth and Mars.
32 kg m/s would be the kinetic energy.
Kinetic Energy, or K.E is equal to 1/2 times the mass of an object times the velocity squared.
Therefore K.E

which is 225
Energy is expressed in joules (J)
so the K.E of the ball is 225J
Hope this helped
Answer:Balance Forces
Explanation:
Balanced Forces are equal in magnitude and opposite in direction that acts on the same body. Whenever balanced forces act on an object the object is either still or moving in the same direction with constant velocity.
example of Balanced Forces are
- Consider a block lying on the ground and is being pulled by two forces of equal magnitude but in acting in the opposite direction. As a result, the block is at rest.
Answer:
a) Energy density of the magnetic field, u = 183.46 J/m³
b) Total energy, E = 0.167 J
Explanation:
a) Number of turns in the solenoid, N = 1410
Area, A = 13.8 cm² = 0.00138 m²
Current, I = 8.01 A
Length of the solenoid, l = 66.1 cm = 0.661 m
Energy density, u is given by the formula 
Where B is the magnetic field
The magnetic field in a solenoid is given by the formula, 

T

b) The total energy = Energy density * Volume
E = u V
Volume = Area * Length
V = Al = 0.00138 * 0.661
V = 0.00091218 m³
E = 183.46 * 0.00091218
E = 0.167 J
