2018
✓ Answer:C625 J
W = mgh = 25 × 10 × 2.5 = 625 J.
402
Which equation relates power P to energy E and time t?
RRB Technician Grade-I

2024
✓ Answer:DP = E/t
Power is energy transferred per unit time: P = E/t.
403
A 50 kg boy climbs 40 stairs in 10 seconds. Each stair is 15 cm high. Find his power. (g = 10 m/s²)
RRB Group D
23/10/2018 / Shift-I
2018
✓ Answer:C300 W
h = 6 m. P = mgh/t = 50 × 10 × 6/10 = 300 W.
404
A 10 kg object is raised 5 m above the ground. Calculate its energy. (g = 9.8 m/s²)
RRB ALP (Stage-II)
06/05/2025 / Shift-I
2025
✓ Answer:B490 J
U = mgh = 10 × 9.8 × 5 = 490 J.
405
