The melting of polar ice is one effect of the greenhouse effect, or also global warming.
The greenhouse effect, as defined by Merriam-Webster, is "the <span>warming of the surface and lower atmosphere of a planet (as Earth or Venus) that is caused by conversion of solar radiation into heat in a process involving selective transmission of short wave solar radiation by the atmosphere, its absorption by the planet's surface, and reradiation as infrared which is absorbed and partly reradiated back to the surface by atmospheric gases".
In short, "</span>the warming of the surface and lower atmosphere of a planet".
Answer:
The car exerts the same sized force on the bug as the bug exerts on the car.
Explanation:
Given that
Speed of car = 70 mph
Third law of Newton's
It state that when an object A apply force on the another object B then object B also apply the same force on the object A but in opposite direction .This is known as action reaction .In simple words every action and reaction.
By using the third law of concept,when car and a bug collides then car exerts the same sized force on the bug as the bug exerts on the car.
Answer:
<h3>The answer is 0.67 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
![a = \frac{f}{m} \\](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bf%7D%7Bm%7D%20%20%5C%5C%20)
f is the force
m is the mass
From the question we have
![a = \frac{20}{30} = \frac{2}{3} \\ = 0.6666666...](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B20%7D%7B30%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20%20%5C%5C%20%20%3D%200.6666666...)
We have the final answer as
<h3>0.67 m/s²</h3>
Hope this helps you
All are correct except
Aerobic respiration is only done by animal cells but anaerobic is done by plant and animal cells.
Hope this helps!
