As you know, plants are usually green<span>, which means that most other colors are absorbed. One of the most common pigments is called chlorophyll, and one of the varieties is responsible for the </span>green<span> color of plants; it strongly absorbs </span>blue<span> and </span>red<span>light, which leaves only the </span>green<span> light to make it to our eyes.</span>
Answer:
Given:
mass of the ball m = 0.144 kg
velocity v = 38 m/s
now, change in momentum
P = m v- ( - mv)
= 2 mv
=2 x (0.144) x (38)
= 10.944 kg-m/s
Impulse J= F. Δt
change in momentum is equal to impulse
J = 10.944 kg-m/s
we know force is equal to change in momentum per unit time
F = 13.68 x 10³ N
F = 13.68 kN

Explanation:
<u>Answer:</u>
The correct answer option is: they are equal and opposite.
<u>Explanation:</u>
A force is a push or a pull which acts upon any object as a result of its interaction with another object where the forces are called action and reaction.
And according to the Newton's third law: for every action, there is an equal and opposite reaction.
For example, if a bat hits a ball with a 1000-N force, the force exerted on the bat will also be equal to 1000 N but in opposite direction.
Answer:
rpm= 916.7436 rev/min
Explanation:
First determine the perimeter of the wheel, to know the horizontal distance it travels in a revolution:
perimeter= π×diameter= π × 22 inches × 0.0254(m/inche)= 1.7555m
Time we divide the speed of the car, which is the distance traveled horizontally over time unit, by the perimeter of the wheel that is the horizontal distance traveled in a revolution, this dates us the revolutions over the time unit:
revolutions per time= velocity/perimeter
velocity= (60 mi/hr) × (1609.34m/mi) = 96560m/h
revolutions per time= (96560.6m/h) / (1.7555m)= 55004.614 rev/hr
rpm= (55004.614 rev/hr) × (hr/60min)= 916.7436 rev/min
