My guess would be choice D
Acceleration = force / mass.
A = 100/50 = 2 m/s^2 .
Answer:
In an elastic collision, the momentum is conserved and the mechanical energy is conserved too.
Explanation:
There are two types of collisions:
- Elastic collision: in an elastic collision, the total momentum before and after the collision is conserved; also, the total mechanical energy before and after the collision is conserved.
- Inelastic collision: in an inelastic collision, the total momentum before and after the colllision is conserved, while the total mechanical energy is not conserved (in fact, part of the energy is converted into other forms of energy such that thermal energy, due to the presence of frictional forces)
Explanation:
Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum.
Answer:
I think it is the 3 option
