According to this equation

F = G × m₁*m₂ ÷ r²

other than the mass, the distance also affects the gravitational force between two objects (same mass or not).

Therefore the correct answer is B. The distance between the objects

Future note* use formulas to help you figure these sort of questions out. (if they have a formula to begin with).

A child in a boat throws a 4.5kg package out horizontally with a speed of 13 m/s. Calculate the velocity of the boat immediately
Varvara68 [4.7K]

Answer:

0.78m/s

Explanation:

Now the momentum ensued by the boy throwing the package Is

Mass of package × velocity of package =4.5×13=58.5m/s

This momentum initiated a momentum on the boy-boat system

Total mass of the boy-boat system is 24+53=75kg

Let the velocity ensued by the boat be v.

Hence from conservation of momentum

58.5 =75×v

v= 58.5/75= 0.78m/s

A process generates 250 watts of useful energy and 600 watts of waste energy. WhT is the efficiency of the process?
Cloud [144]

The efficiency of the process is 42%

From the question given above, the following data were obtained:

Useful energy = 250 watt

Wasteful energy = 600 watt

<h3>Efficiency =? </h3>

The efficiency of the process can be obtained as illustrated below:

efficiency \:  =  \frac{useful \: energy}{wasteful \: energy}  \times 100 \\  \\ efficiency \:  =  \frac{250}{600}  \times 100 \\

<h3>Efficiency = 42%</h3>

Therefore, the efficiency of the process is 42%
