Answer:t
Explanation:
Given that,
Power output is
P = 0.50kW = 0.5 × 1000 = 500W.
We want to find energy transfer in
t = 2minutes = 2 × 60 = 120 seconds
Also, time to hour
t = 2/60 = 1/30 hour
Power is the rate of energy.
Therefore,
Power = energy / time taken
Energy = power × time taken
Energy = 0.5kW × 1/30 hr
Energy = 0.01667 kWh
Also, energy in Joule
Energy = power × time
Energy = 500W × 120s
Energy = 60,000J
Energy = 60kJ.
Given:
A cylindrical container closed of both end has a radius of 7cm and height of 6cm.
Explanation:
A.) Find the total surface area of the container.
- A = 2πrh + 2πr²
- A = 2(3.14)(7)(6) + 2(3.14)(7 × 7)
- A = 263.76 + 307.72
- A = 571.48
B.) Find the volume of the container.
- V = πr²h
- V = (3.14)(7×7)(6)
- V = 923.16
