The mass of water moving around on Earth’s surface causes the amount of gravitational force.
I think it should be 'They are balanced' if I'm not wrong
Explanation:
We have,
The initial position of an object is zero.
The starting velocity is 3 m/s and the final velocity was 10 m/s.
The object moves with constant acceleration..
The area covered under the velocity-time graph gives displacement of the object. The correct option is "the area of the rectangle plus the area of the triangle under the line".
For those seeking for the answer, its a source of electrical energy.
