The force will remain same if the mass of each sphere is doubled and the distance between them is doubled as well.

The force of gravitation between two spheres is given by

f=\frac{G m1 m2}{r^{2}}

m1= mass of first object

m2= mass of second object

r= distance between the masses

Now if each mass is doubled and the distance r is doubled as well

F'= \frac{G (2m1)(2m2)}{(2r)^{2}}

F'= \frac{4 G m1 m2}{4r^{2}}

F'=\frac{G m1 m2 }{r^{2}}

so F'= F

so the force remains same and is equal to 1000 N.

A car accelerates at 3 m/s*2. Assuming the car starts from rest, how much time does it need to
uranmaximum [27]
<h3><u>Given</u><u>:</u><u>-</u></h3>

Acceleration,a = 3 m/s²

Initial velocity,u = 0 m/s

Final velocity,v = 12 m/s

<h3><u>To</u><u> </u><u>be</u><u> </u><u>calculated:-</u><u> </u></h3>

Calculate the time take by a car.

<h3><u>Solution:-</u><u> </u></h3>

According to the first equation of motion:

v = u + at

★ Substituting the values in the above formula,we get:

⇒ 12 = 0 + 3 × t

⇒ 12 = 3t

⇒ 3t = 12

⇒ t = 12/3

⇒ t = 4 sec

A block and tackle is used to lift an automobile engine that weighs 1800 N. The person exerts a force of 300 N to lift the engin
Sidana [21]

Answer:

1800/300 = 6ropes

Explanation:

The engine weighs 1800N and the person exerts a force of 300N, so for him to lift the engine and exerting a force of 300N all through we divide the weight of the engine by the force exerted to know how many ropes are used. Which makes it 6 thereby each rope uses 300N to lift the engine.
