Answer:
Explanation:
As we know that the ball is swinging in a circle
so here net horizontal centripetal force on the ball is due to component of the tension force
so we will have
also we know that
so we have
now we have
now we have
Answer:
The Fahrenheit scale defines the freezing point of water as 32°F and the boiling point as 212°F. The Celsius scale sets the freezing point and boiling point of water at 0°C and 100°C respectively.
No that's not true I believe only lightning is electrically charged because it can shock you.
Answer:
The average emf induced in the loop is 0.25 V
Explanation:
Given;
area of loop, A = 0.20 m²
strength of magnetic field, B = 50 mT
time, t = 40 ms
where;
Φ is magnetic flux, this is maximum when the plane of the loop is parallel to the magnetic field.
Φ = BA
induced emf = BA / t
induced emf = (50 mT x 0.20 m² ) / (40 ms)
induced emf = 0.25 V
Therefore, the average emf induced in the loop is 0.25 V
