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.
The correct answer for this question is this one: "b. increased prices." <span>The small increase in global oil production coupled with an increased demand for those resources leads to increase in prices.
</span>
Here are the following choices.
<span>a.
lack of modern energy sources
b.
increased prices
c.
decreased competition
d.
decreased prices</span>
Your weight will be less than on Earth because in space there is no or very less gravitational pull. There are no planets forming any magnetic fields for other objects to be attracted to.
Work done by gravity = 23,520 J = mgh. Therefore m= 23520/ 30 x 9.8 = 80 kg.
The kinetic energy of the car is
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion.
Mathematically, the kinetic energy is
where
m is the mass of the object
v is its speed
For the car in this problem,
m = 740 kg
v = 33.5 m/s
Therefore, the kinetic energy of the car is
