As per Faraday's law of induction we know that induced EMF in a conducting closed loop is equal to rate of change in flux in that loop
So here we have
now when we move out a coil from magnetic field then in this case there will be EMF induced in that coil as here magnetic flux is changing with time linked with the coil.
Now this induced voltage will remain constant if coil is moved out uniformly
But it will not remain constant if coil is moved out with non uniform speed
So this statement is not always true
so answer must be
<u>FALSE</u>
Answer:
B. over the symbol.
Explanation:
vectors are represented with a symbol carrying an arrow head with also indicates direction
Answer:
Both balls will hit the ground at the same time
Explanation:
The factor which leads to ball falling is the gravity acting on the ball;
The motions along the path of both balls are independent and both balls will obey the following illustration
Using the third equation of motion
s = ut + ½at²
Where s = distance covered by both balls.
u = initial velocity of both balls. Since both balls start from rest, u = 0m/s
a = acceleration; and it's equal to acceleration due to gravity.
a = g
By substituton
s = 0 * t + ½gt²
s = 0 + ½gt²
s = ½gt²
Make t the subject of formula
gt² = 2s
t² = 2s/g
t = ±√(2s/g)
But time can't be less than 0 (in other words, negative)
So,
t = √(2s/g)
It'll take both balls √(2s/g) time to hit the floor
Answer:
100 newton
Explanation:
newton third law of motion says to every action there is an always an equal and opposite reaction so the magnitude will stay equal but opposite direction
Answer:
there are no provision to head it
Explanation:
because there are no oxygen
