Spinning a marshmallow over a fire is effective maybe if you hang it over the fire and heat it up equally on each side
Answer:
4.9 m/s
Explanation:
Since the motion of the ball is a uniformly accelerated motion (constant acceleration), we can solve the problem by using the following suvat equation:

where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
For the ball in this problem,
u = 0 (it starts from rest)
is the acceleration
s = 3 m is the distance covered
Solving for v,

Answer:
The potential energy increases and the kinetic energy decreases
Answer:
light doesn't need a medium through which to travel because the speed of light is experimentally constant
Answer: 57.79%
Explanation: 152J/263J=.577946768 or 57.79% or roundedthe nearest whole percent is 58%
