Answer:
The total area of rooftop solar panels is 130.61 m².
Explanation:
Given that,
Efficiency = 15%
Intensity of sunlight
Power = 19.2 kW/d
Let sun's power need be P.
We need to calculate the power
We need to calculate the total area of rooftop solar panels
Using formula of power
Where, I = intensity
A = area
P = power
Put the value into the formula
Hence, The total area of rooftop solar panels is 130.61 m².
Answer: The mass of ball is 10 grams.
Explanation:
Given : Kinetic energy = 4.5 J
Velocity = 30 m/s
The formula for Kinetic energy is as follows.
where,
K.E = Kinetic energy
m = mass
v = velocity
Substitute the values into above formula as follows.
Thus, we can conclude that the mass of ball is 10 grams.
