Nata [24]
Hello!

Answer:

2000 J

Explanation

Work equation is expressed as:

W=F.d.Cos \alpha

Where:

F: Applied force
d: traveled distance
α: Angle between the direction of the force and the direction of the movement. (in this case, both of the direction are the same, so the angle is 0°)

By substituting:

F=1000N.2m.Cos(0)=2000N.m=2000 J

Have a nice day!

What happens when you throw a basketball up toward the hoop? If you are lucky, the ball sinks into the net. You score two points
Ray Of Light [21]

Answer:

What happens when you throw a basketball up

toward the hoop? If you are lucky, the ball sinks

into the net, scoring two points before dropping

back down to the ground. The basketball isn’t

that heavy, so why doesn’t it stay up in the air

<h2>when you throw it? Have you ever heard the</h2>

saying, “What comes up must come down”?

This saying is a simple explanation for what

causes the basketball to fall back to the ground.

It is being acted on by an invisible force called

gravity, which is the basic force in the universe

that attracts all objects to each other.

1 Gravity has existed since the beginning of the universe. It is hard to understand how or why it

works, but we know it is always there because it holds everything in the universe in place. First,

you need to understand that there is a gravitational attraction between you and Earth, between

Earth and the Moon, and between Earth and the Sun. Even though you can’t feel it, the

gravitational attraction between you and Earth is what keeps your feet planted firmly on the

ground. Imagine spinning around and around on a merry-go-round. As long as you are holding

on, then you stay on the merry-go-round, but if you ever let go, you will fly off and land on the

ground. This is a useful analogy in visualizing the gravitational attraction between Earth and

you. Earth is spinning on its axis and thanks to gravity, you are held to your position on Eart

rather than flying out into space. Explanation: this is what i can do!:)

Why does a paper clip sink and a big ocean liner float? explain your answer.
slamgirl [31]

<span>Because of the density of the paperclip it sinks, but even though a boat is normally made of steal it contains an opposite force of gravity known as buoyancy. Buoyancy is the reason that a boat will float.  Boat density is less weight than the water they are in so this is one reason that they are floaters.</span>
