An engine moves a motorboat through water at a constant velocity of 22 meters/second. if the force exerted by the motor on the boat is 5.75 × 103 newtons, what is the power of the motor? a. 7.9 × 104 watts b. 1.3 × 105 watts c. 2.5 × 105 watts d. 3.7 × 105 watts e. 5.0 × 105 watts

Option B: 1.3×10⁵ W

Explanation:

Work Done,

Where s is displacement in the direction of force and F is force.

where, v is the velocity.

It is given that, F = 5.75 × 10³N

v = 22 m/s

P = 5.75 × 10³N×22 m/s = 126.5 × 10³ W ≈1.3×10⁵W

Thus, the correct option is B

explanation:

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
