The fixed the the lever pivots around is called the fulcrum
The gravitational forces between two masses are inversely proportional to
the square of the distance between the centers of the masses.
So if the distance between the <u>centers</u> of the asteroids is multiplied by 1/2,
then the gravitational forces between them are multiplied by ...
1 / (1/2)² = (2)² = 4 .
The new force is (100N) x (4) = <em>400N</em>.
Answer:
10 metres
Explanation:
So, we are given the following data or parameters or information which is going to assist us in solving this particular problem or Question efficiently.
=> The speed of the space ship can be found from this relationship: ✓(1 - [v^2/c^2] ) = 1/2.
=> The length of the space ship = 20 m.
=> Assumption = '' If the length of the ship is measured by the inertial earth-bound observer".
Thus, from the speed of the space ship can be found from this relationship we can determine the value;
✓(1 - [v^2/c^2] ) = 1/2.
V = 20 × 1/2 = 10 metres.
Note that we use the contraction formula to solve for V.
In order to answer either of these, we need to know the energy content of coal ... like kwh (or joules or BTU) in each kilogram (or pound or ton) of coal.
Answer:
1.76 m/s^2
Explanation:
The formula to find the force is F = ma (reference from 2nd law of Newton's Laws of Motion). Since you need to find the acceleration of the box, you need to use the formula a = f/m
a = 9.7 n divided by 5.5 kg = 1.76 m/s^2
