Given
F = 55 N to ring the bell
P = 250 W
t = 0.85 s
Procedure
First let's calculate the force for 250W of power.

With 250W it is not possible to reach the bell to ring it.
Now let's calculate the value for 500W

Force is doubled when power is doubled
Distance traveled by car =14m
Total time taken =2sec
Speed =distance / time
=14m/2sec
speed=7 m/sec
Answer:
Sound waves are longitudinal waves
Explanation:
Sound waves are the longitudinal waves. In longitudinal waves, the particles of the wave move parallel to the direction of propagation of waves.
It moves in the form of compression and rarefaction. When the particles are compact in a space the compression occurs while when they far apart form each other rarefaction occurs.
Answer:
the answer is C
Explanation:
gravity forces down not up or sideways.
Answer:

Explanation:
Since the mitochondria is in charge of producing ATP the tiger would not be able to use any glucose causing it to not be able to run.
