Bad, it's bring more hatred to the world
Answer: 50 gram superball that strikes the wall at 1 m/s and bounces away at 0.8 m/s has greater change in kinetic energy.
Explanation:
50 gram superball that strikes the wall at 1 m/s and bounces away at 0.8 m/s has the greater change in kinetic energy because the collision is elastic in nature that is bodies separates after collision and doesn't lose any kinetic energy.
Also for an elastic collision, both the momentum and energy of the bodies are conserved compare to inelastic collision where only momentum is conserved but not the kinetic energy(this is attributed to bodies that sticks together after collision).
Answer:
Time, t = 0.57 hours
Explanation:
It is given that,
Speed of the school bus, v = 35 mi/hr
Distance covered by the bus, d = 20 miles
We need to find the time taken by the bus to get to school. Time taken by the bus is given by :
t = 0.57 hours
So, the time taken by the bus to reach school is 0.57 hours. Hence, this is the required solution.
The sodium atom, Na, contains 11 protons, 11 electrons, and 13 neutrons.
