Physics
1 answer:
scoundrel [369]4 years ago
8 0

Answer:

Option A is the correct answer.

Explanation:

The instantaneous acceleration = Change in velocity in velocity/Time taken

The slope of the graph should give instantaneous acceleration.

 Slope of a graph = Change in value of Y -axis / Change in values of X -axis

 Comparing both the equations

   Change in value of Y -axis = Change in velocity in velocity

   Change in values of X -axis = Time taken

So velocity values should be on the Y axis and Time values should be on the X axis.

Option A is the correct answer.

A small planet having a radius of 1000 km exerts a gravitational force of 100 N on an object that is 500 km above its surface. I
Mars2501 [29]
<h2>Option C is the correct answer.</h2>

Explanation:

Gravitational force is given by

                  F=\frac{GMm}{r^2}

         G=6.674×10⁻¹¹ m³⋅kg⁻¹⋅s⁻²

         M = Mass of object 1

          m = mass of object 2

          r = Distance between objects.

Here only variable is r value.

In case 1

             100=\frac{GMm}{(1000+500)^2}\\\\GMm=100\times 1500^2

In case 2

            F=\frac{GMm}{(1000+500+500)^2}\\\\F=\frac{GMm}{2000^2}\\\\F=\frac{100\times 1500^2}{2000^2}\\\\F=56.25N

Option C is the correct answer.
