How would increased chlorofluorocarbons (CFCs) in the atmosphere affect the growth of vegetation throughout the world?

Ultraviolet light will increase on earth's surface. It will "raise" temperatures and decrease plant populations.
Actually UV rays do not increase temperature, that's wrong.
They cause mutations in several organisms as they modify their DNA. They also cause skin cancer in humans and also cataracts and sunburns.
But they don't increase temperature.
That's carbon dioxide accumulation.

The net force on an object is 80 N. The mass of the object is 40 kg.
Art [367]

Answer:

The acceleration of object is 2 m.s⁻².

Explanation:

Given data:

Force on object = 80N

Mass of object = 40 kg

Acceleration = ?

Definition:

The acceleration is rate of change of velocity of an object with respect to time.

Formula:

a = Δv/Δt

a = acceleration

Δv = change in velocity

Δt = change in time

Units:

The unit of acceleration is m.s⁻².

Acceleration can also be determine through following formula,

F = m × a

a = F/m

Now we will put the values in formula.

a = 80 N/40 kg

a = 2 m.s⁻²  (N = Kgm.s⁻² )
