Answer:
64 J
Explanation:
W = ΔPE
W = mgΔh
W = (130 kg) (9.8 m/s²) (0.050 m)
W = 64 J
Answer:
100J
Explanation:
When you raised the object by 14 its store potential energy If we take ground level as its potential energy is zero. When its falling all the potential energy is transferred to the kinetic energy. According to the conservation of energy then
Potential energy = Kinetic Energy
Answer:
Position of the object at t = 5 s is centimeter
Explanation:
The position of object as a function of time can be represented as
It is given that at t seconds the position of the object is centimeter.
We will substitute these values to determine the value of
Velocity at initial stage when t seconds is
Position after seconds
Answer:
A theory or hypothesis does not necessarily provide an accurate scientific explanation to any topic but predicts what can happen.
Explanation:
Answer:
The specific latent heat of a substance is the amount of energy required to change the state of one kilo of the substance without change in it temperature.The latent heat of vaporization or evaporation is the heat given to some mass to convert if from the liquid to the vapor phase.
