Question

(5) To obtain a given moment of force for turning a body, the force needed can be decreased by:

1 point

Applying the force at a pivoted point

None of the above

Applying the force very close to the pivoted point

Applying the force farthest from the pivoted point

(6) The water stored in a tank on the top of the roof has_____.

1 point

Potential energy

Kinetic energy

Both potential and kinetic energy

Solar energy

​

Answer 1

Answer:

5) Moment of force = force × perpendicular distance of force – from the pivoted point. Less force is needed when applied at a farther distance from the pivoted point. For a given thrust, pressure is more on a surface of large j area. The pressure on a surface increases with an increase in the thrust on the surface.

6)As the water stored in overhead tank is not in motion, so it possesses potential energy.

Answer 2

Answer:

kinetic energy hope it helps uu
