Answer:
Explanation:
Given that
Temperature of warm water ,T₁ = 25 °C
Temperature of cold water ,T₂ = 5 °C
The maximum possible efficiency of any heat is will be same as the efficiency of the Carnot heat engine.Therefore the maximum efficiency of OTEC system is given as follows
T should be Kelvin scale
Now by putting the values
Therefore the maximum efficiency will be 0.067 or 6.7%.
Answer:
Explanation:
initial angular velocity, ωo = 0
angular acceleration = α
time = t
let the angular velocity after time t is ω.
Use first equation of motion for rotational motion
ω = o + α t
ω = αt
The angular momentum is given by
Angular momentum = moment of inertia x angular velocity
L = I x ω
L = I x αt
L = I α t

Weight is essentially just a measurement of the force of gravity, so you can use this equation.
F = mg
Force = Mass × Acceleration due to Gravity
F = 19kg × 9.8m/s^2. (Acceleration due to Gravity on Earth.)
F = 186.02N
