Answer:

(A) more rapidly than

Explanation:

With higher temperatures, object's molecules (and atoms) have higher kinetic energy which is due to faster "jiggling" (vibrations). On a hot day these vibrations in the material the sidewalk is made of are more rapid than on a cold day, just as their temperatures differ.

a 2,000 pound car is driving at 60 miles/hour along a straight, level road. what is the net force acting on the car?
SVETLANKA909090 [29]

Answer:

0

Explanation:

According to Newton's second law, the net force is equal to the mass times the acceleration.  Since the car is not accelerating, the net force is 0.

Jody does long distance running and also strength trains twice a week.
murzikaleks [220]

<u>Answer:</u>

<em>Jody will have strong bones and show muscle hypertrophy. </em>

<u>Explanation:</u>

Long distance running practiced regularly helps in <em>increasing the strength of bones</em>. Muscular hypertrophy is the increase in mass of skeletal muscles due to the increase in the size of myofibrils or increase in muscle glycogen storage. <em>Strength training exercises</em> performed regularly induce muscular hypertrophy.

During strength <em>training exercises muscles</em> undergo contraction and repeated contraction breaks muscle fibres. New muscle fibres are added as a means of repair and this happens at the relaxing phase of muscles. More muscle fibres are added to <em>compensate the damage and thus muscle mass increases. </em>

4. A 75 kg bobsled is pushed along a horizontal surface by two athletes. After the
vlada-n [284]

The net force on the sled is 300 N

Explanation:

First of all, we start by finding the acceleration of the bobsled, by using the suvat equation:

v^2-u^2=2as

where:

v = 6.0 m/s is the final velocity of the sled

u = 0 is the initial velocity

a is the acceleration

s = 4.5 m is the displacement of the sled

Solving for a, we find

a=\frac{v^2-u^2}{2s}=\frac{6.0^2-0}{2(4.5)}=4 m/s^2

Now we can find the net force on the sled by using Newton's second law:

F = ma

where

F is the net force

m = 75 kg is the mass of the sled

a=4 m/s^2 is the acceleration

Solving the equation, we find the net force:

F=(75)(4)=300 N
