B. the object's speed and mass
Looking at the kinetic energy formula:
1/2mv^2 = Ek
It can be seen that the only two factors that affect the magnitude of the kinetic energy are mass and the object speed. Kinetic energy is also a scalar quantity so the direction is unnecessary.
Answer: energy
Explanation: So the input and output of the power grid system is energy.
Answer:
Momentum of object A = Momentum of object C < momentum of B.
Explanation:
The momentum of an object is equal to the product of mass and velocity.
Object A has a mass m and a speed v. Its momentum is :
p = mv
Object B has a mass m/2 and a speed 4v. Its momentum is :
p = (m/2)×4v = 2mv
Object C has a mass 3m and a speed v/3. Its momentum is :
p = (3m)×(v/3) = mv
So,
Momentum of object A = Momentum of object C < momentum of B.
