Answer:
10.028%
Explanation:
= Angle between polarizer
The polarized light after passing through first polarizer
The polarized light after passing through second polarizer
The polarized light after passing through third polarizer
The percent of the light gets through this combination of filters is 10.028%
Answer:
The magnetic field points northwards
Explanation:
This is because a radial magnetic field is generated round the wire and its direction is always in the direction of the tangent to the circle at distance R from the wire. Due east of the wire, the tangent to the circle at radius, R points northwards. So, the direction of the magnetic field at that point is north.
Time is being measured in days here so if you want to calculate the rate of increase after one day, substitute 1 for t in your rate equation:
dB/dt = 0.677598 cos(1.232(1))
dB/dt = 0.22
Answer:
Explanation:
Given that,
Initial speed of a body, u = 0
Final speed of the body, v = 20 m/s
Time, t = 5 s
We need to find the acceleration of the body. We know that the acceleration of an object is equal to the rate of change of velocity divided by time taken. So,
So, the body's acceleration is equal to .
