Answer:
11.125°
Explanation:
Given:
Radius of bend, R = 100 m
Speed around the bend = 50 Km/hr = = 13.89 m/s
Now,
We have the relation
where,
θ = angle of banking
g is the acceleration due to gravity
on substituting the respective values, we get
or
or
θ = 11.125°
Answer:
c
Explanation:
A data graph has been attached to the given question which is of the year 2018.
According to it of 101.3 quad Btu total energy produced in USA, 11% is produced by renewable energy resources. that consists of 22% of from wind energy.
there amount of energy produced through wind is 22% of 11% of 101.3 quad Btu, which will be roughly about 2.5 quad Btu
Btu here is British thermal Unit.
hence option c is correct
Answer:
Explanation:
Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity. The attached diagram give an ilustsration of the photovotaic pannel mounted on a roof top.
Solution
To Determine the electric power generated for
a) A still summer day.
E = A * r * H * PR
E = Total Amount of Energy in kilowatt
A = Total Surface Area
r = efficiency Rating
H = global radiation value
PR = Performance Ratio
kwh = watt * Time/1000
kwh = 100 * 35/1000
3.5
b)
kwh = watt * Time/1000
kwh = 30 *15/1000
4.5
