A capacitor is an electronic component that stores and releases electricity in a circuit.
Answer:
Part a)
Part b)
Explanation:
Diameter of the circle = 24 ft
Diameter = 731.52 cm = 7.3152 m
now the horse complete 144 trips in one hour
so time to complete one trip is given as
now the speed of the horse is given as
Part a)
Now we know that the power is defined as rate of work done
it is given as
Part b)
Work done to climb up to 3 m height is given by
now we have
now we know that 1 HP = 746 Watt
so we have
No each atom bonds in a different way according to what does it bonds with
Answer:
B.
The light waves are completely blocked.
Explanation:
The intensity of the light coming out after two polarizers is given by Malus' Law:
where
is the initial intensity of light before the polarizers
is the intensity of light after the two polarizers
is the angle between the axes of the two polarizers
In this problem, we have two polarizers with their axes placed perpendicular to each other: this means that the angle is 90 degrees
Therefore, the cosine factor is zero:
And this means that the intensity of light after the two polarizers is also zero:
So, the correct option is
B. The light waves are completely blocked.
