Answer:
1570 V
Explanation:
N = 100
diameter = 2 m
radius = 1 m
B = 5 tesla
initailly the angle between the area vector of the coil and the magnetic field is zero and then the angle becomes 180 degree.
t = 2 s
Let Φ be the initial magnetic flux.
Φ = B A Cos 0 = 5 x 3.14 x 1 x 1 x 1 = 15.7 Wb
Let Φ' be the final magnetic flux
Φ' = B A Cos 180 = - 5 x 3,14 x 1 x 1 x 1 = - 15.7 Wb
According to the law of electromagnetic induction, the induced emf developed is equal to the rate of change of magnetic flux linked with the coil.
Answer:
1%
Explanation: A cassegrain telescope is a kind of telescope which is made up of the curved mirrors one of the mirrors is a concave mirror is called the primary mirror and the second mirror called the secondary mirror which is a convex mirror, when light Penetrate the cassegrain telescope, it first hits the primary concave mirror and it's then reflected by the secondary convex mirror.
Answer:
The angular acceleration is same at all the points in the body.
Option (D) is correct.
Explanation:
Given:
When a rigid body rotates about a fixed axis, all the points in the body have the same,
For finding which quantity is same we use pure rotational concept,
Where 
angular frequency, 
radius of rigid body
When a rigid body rotates about a fixed axis angular velocity of all the points in the body are same.
But the tangential speed, tangential acceleration, linear displacement, and centripetal acceleration depend on the position of the points and hence they are not the same.
Therefore, the angular acceleration is same at all the points in the body.
Explanation :
Takumi wears sunscreen and a hat each time he works in the yard. This is to protect himself with the strong radiation coming from the sun. UV rays that are coming from the sun are the main cause of skin cancer.
Stochastic effects are the effects that are caused by chance. Cancer is one of the main stochastic effects.
So, the correct option is (b) "the severity of stochastic effects, such as cancer".
