It is called Gravity. For gravity is the force that causes our feet to stay on the ground. It was Newtons first universal law of gravitation.

"What goes up ...must come down."          

Example : If I were to throw a rock up at the sky , It will come down in no time.
_____________________________________________________

Gravity is also what keeps the planets in our solar system , it's what keeps us in the suns gravitational pull.


I really hope that this helps

Gravity is the force that makes objects fall towards the Earth. All objects in the Universe exert a gravitational pull. The student will "fall" towards the ground because the Earth is exerting a gravitational pull on him.

Ned the skydiver weighs 600 N and is falling at terminal speed. That is, he has sped up until air resistance has built up so muc
natali 33 [55]

Answer:

The work done is 120000 J.

Explanation:

Given that,

Weight = 600 N

Distance = 200 m

We need to calculate the work done

Using formula of work done

W=F\times d

Where, F = force

d = distance

Put the value into the formula

W=600\times200

W=120000\ J

Hence, The work done is 120000 J.

A 20-volt relay has a coil resistance of 200 ohms. How much current does it draw? (I=0.1A)
TEA [102]

Answer:

Explanation:

a) According to ohm's law

V = IR

V is the supply voltage

R is the resistance

I is the current

Given Resistance = 200ohms

Voltage = 20V

I = V/R

I = 20/200

I = 0.1Amperes

b) Using the ohm's law formula

V= IR

Where voltage = 12volts

Current I = 3A

Resistance R = V/I

R = 12/3

R = 4ohms

c) Power generated by the battery is expressed as P = IV

I = P/V

Given Power = 2Watts

V = 1.5volts

I = 2/1.5

I = 1.33A

d) similarly, power = current I × voltage V

V = P/I

Given P = 90watts

I = 4.5A

V = 90/4.5

V = 20volts

e) Given power = 1.5kW = 1500watts

Voltage = 300volts

I = P/V

I = 1500/300

I = 5A

Answer:

Well my good friend the other person did not give U a good answer, it is actually the third one

Explanation: well it is the most logical of all the answers if you think about it and a lot of the creatures we have in the water today are thought of to have once lived on land based on the fossils we still find to this very day my friend

<span>A) The effort force is always smaller than the force needed without the machine. 

It is because some of the work (by force) is lost during the conversion

Hope this helps!</span>
