Mass of Derrick at a height 4.3 m having 2730 joule of energy is 65 Kg.

<h3>What is the expression of gravitational potential energy near the earth surface?</h3>
  • Mathematically, gravitational potential energy near the earth surface= m×g×h
  • m= mass of Derrick, g= acceleration due to gravity, h= height at which Derrick present
  • Then, mass (m) of Derrick = potential energy/ (g×h)

<h3>What is the mass of Derrick, if he gains 2730 joule of energy at 4.3m above the ground?</h3>

Mass of Derrick= 2730/(9.8×4.3)

= 65 kg

Thus, we can conclude that the mass of Derrick is 65 Kg.

What is the resistance (R) when voltage is 179V and current is 5 Amps?
Evgesh-ka [11]

Answer:

R = 35.8 Ω

Explanation:

Recall Ohm's Law:

V = I * R

then R = V / I

in our case:

R = 179 V / 5 A = 35.8 Ω
