Explanation:

The mathematical expression for the kinetic energy is given by :

E_k=\dfrac{1}{2}mv^2

Where

m is the mass of the object

v is the velocity with which the object is moving

According to given condition, if the speed of an object doubles, v' = 2v. So, kinetic energy becomes :

E_k'=\dfrac{1}{2}m(2v)^2

E_k'=4\times \dfrac{1}{2}mv^2

E_k'=4\times E_k

So, if the speed of an object doubles, its kinetic energy becomes four times. Hence, this is the required solution.

A net downward force of 20 N causes a book to fall towards the ground at m/s2. What is the book’s mass? Consider air resistance
stira [4]

If we have to figure air resistance into it, then we don't have enough information to find an answer.  

If the air around it is going to have an effect on how it falls, then it'll depend on the thickness of the book, the shape of the book, whether it's a hard-cover or soft-cover, how far the covers stick out past the pages, how smooth or rough the covers are, how bumpy the binding it. and what position you hold it in before you let it go.

(THAT's why we always ignore air resistance, especially when the question is actually about gravity anyway.)

Is the sun yellow or is it orange.
LiRa [457]

Answer:

But the Sun isn't actually yellow; it's just an illusion caused by the Earth's atmosphere. The powerful processes happening inside the Sun are so robust that it emits every color of light imaginable. Together, these colors form a pure white light, which is precisely what you'd see from space.
