i think photons with shorter wavelengths have larger speed.
I apologise if its incorrect.
Answer:
0.48 m
Explanation:
I'm assuming that this takes place in an ideal situation, where we neglect a host of factors such as friction, weight of the spring and others
If the mass is hanging from equilibrium at 0.42 m above the floor, from the question, and it is then pulled 0.06 m below that particular position. This pulling is a means of adding more energy into the spring, when it is released, the weight compresses the spring and equals its distance (i.e, 0.06 m) above the height.
0.42 m + 0.06 m = 0.48 m
At the highest point thus, the height is 0.48 m above the ground.
Answer:
B transferred.
Explanation:
The kinetic energy is simply transferred by transforming it into other forms of energy.
According to the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".
- The moving baseball posses kinetic energy
- As it hits the bat, it is converted to mechanical and thermal energy.
- The bat warms up due to the transfer of the kinetic energy.
- The mechanical energy of the bat cause work to be done on it and it breaks apart.
- This ensures that the energy in this process is conserved.
