Answer:
<u><em>1) if they are moving away from each other it will take 1.43 secs</em></u>
<u><em>2) if they are moving towards each other then it will take 1.11 secs</em></u>
Explanation:
Distance between them is 10 m
Speed ( if they are moving towards each other)= distance/time
time = 10/8+1
time = distance / speed= 10/9= 1.11 secs
if they are moving away from each other than it will take
time = 10/8-1= 10/7= 1.43 secs
Divide the change in speed by the time for the change.
Answer:
central nervous system
peripheral nervous system
Explanation:
The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.Oct 1, 2018
if a volume of air is warmed it expands due to increased translational kinetic energy as it expands it will start to cool.
<h3>When does temperature increase volume?</h3>
We can then conclude that at constant pressure, temperature and volume are directly proportional: temperature increases, volume increases; decrease temperature, decrease volume.
In this case, the higher the temperature, the greater the kinetic energy that acts on the molecules of this gas, so when the gas expands, these molecules find more space and collide less, which will cause the gas to cool.

Answer:
d = 506.25 ft
Explanation:
As we know by kinematics that
here we know that initially the stone is dropped from rest from the edge of the roof
so here initial speed will be zero
now we have
also the acceleration of the stone is due to gravity which is given as
now we have
so from above equation
