Answer: The depletion of the ozone layer is due to CFC (chloro fluoro carbon) which is widely used in air conditioner and refrigeration.

Explanation:

Ozone layer prevents the harmful radiation from entering the earth's surface.

Ultraviolet radiation is very harmful radiation. Exposure of this radiation can cause Skin cancer. It is the main cause of the sunburn.

The depletion of the ozone layer is due to CFC (chloro fluoro carbon) which is widely used in air conditioner and refrigeration.

CFC is broken down by ultraviolet radiation. Then, the chlorine is released. This chlorine reacts with oxygen. In this way, it destroys the ozone molecule.

Answer:

Explanation:  

When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced.

Bess [88]

Answer:

(a). The blood travel during this acceleration is 0.0231 m.

(b). The time for the blood to reach its peak speed is 0.0459 sec.

Explanation:

Given that,

Acceleration = 22.0 m/s²

Speed = 1.01 m/s

(a). We need to calculate the distance

Using equation of motion

v^2=u^2+2as

Where, v = final speed

u = initial speed

a = acceleration

s = distance

Put the value into the formula

(1.01)^2=0+2\times22.0\times s

s=\dfrac{(1.01)^2}{2\times22.0}

s=0.0231\ m

(b). We need to calculate the time

Using equation of motion

v =u+at

Put the value into the formula

1.01=0+22t

t=\dfrac{1.01}{22}

t=0.0459\ sec

Hence, (a). The blood travel during this acceleration is 0.0231 m.

(b). The time for the blood to reach its peak speed is 0.0459 sec.
