Calculate the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.​
vredina [299]

Answer: The rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.

Explanation:

  • The rate of energy transfer from one point to another is known as power.
  • Its SI. unit is <em>Watt.</em>

Formula to compute power:

Power = I^2 R, I = cureent, R = resistance.

Given R = 5 ohm , Current = 0.5 A.

Then, power = (0.5)^2\times 5=0.25\times5=1.25\ watt

Hence, the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.

A rock is dropped from the top of a tower. When it is 40 meters above the ground velocity of 17 m/s. When its velocity is 24 m/s
eimsori [14]

Answer:

Option B is the correct answer.

Explanation:

Let us consider 40 meter above ground as origin.

Initial velocity = 17 m/s

Final velocity = 24 m/s

Acceleration = 9.81 m/s

We have equation of motion v² = u² + 2as

Substituting

         24² = 17² + 2 x 9.81 x s

           s = 14.63 m

Distance traveled by rock = 14.63 m down.

Height of rock from ground = 40 - 14.63 = 25.37 m = 25.4 m

Option B is the correct answer.
