Speed = distance / time = 55 / 0.75 = 73.3 miles per hour.
The kinetic energy of an object is directly proportional to its mass, and to the square of its velocity.
Answer:
B) an electron to move from ground state to an excited state.
Explanation:
Chlorophyll is a pigment that absorbs electromagnetic radiation of the visible spectrum that is used in process of photosynthesis. Chlorophyll's function is to absorb electromagnetic radiation of the visible spectrum and it absorbs blue color radiation the best and green the worst as it reflects it. It absorbs electromagnetic radiation by absorbing the energy of the photon of light by a process called charge separation.
Charge separation is the process by which an electron gets to a higher energy state by absorbing the energy of a photon.
Answer:
<h3>The answer is 6 m/s²</h3>
Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula

where
v is the velocity
t is the time
We have

We have the final answer as
<h3>6 m/s²</h3>
Hope this helps you
