Answer:
a) 2.85 kW
b) $ 432
c) $ 76.95
Explanation:
Average price of electricity = 1 $/40 MJ
Q = 20 kW
Heat energy production = 20.0 KJ/s
Coefficient of performance, K = 7
also
K=(QH)/Win
Now,
Coefficient of Performance, K = (QH)/Win = (QH)/P(in) = 20/P(in) = 7
where
P(in) is the input power
Thus,
P(in) = 20/7 = 2.85 kW
b) Cost = Energy consumed × charges
Cost = ($1/40000kWh) × (16kW × 300 × 3600s)
cost = $ 432
c) cost = (1$/40000kWh) × (2.85 kW × 200 × 3600s) = $76.95
Weight will be 9.8 N

<span>A naturally occurring force related to two bodies in motion is frictional force. Friction is a type of force which includes two bodies resisting each other –either motion of solid surfaces, fluid layers, material elements and compounds gliding against each other. They key point of this frictional force is that the two forces are in the opposite point of direction with each other. For example, when you are cold, as you rub your hands together notice that when your right hand is going upward, your left hand is downward and thus creates heat. That is one type of friction force outcome, the heat.<span>

Answer:
Explanation:
Moment of Inertia about an axis passing through its center and Perpendicular to its Plane is given by
As all the mass is at radius therefore its moment of inertia is more than the moment of inertia about a axis parallel to the Plane
According to perpendicular axis theorem
and is same due to symmetry
thus
thus Perpendicular z axis will have more moment of inertia
Answer:its 2131
