Answer:
<u>The flux decreases because the angle between B⃗ and the coil's axis changes.</u>
<u />
Explanation:
The flux through the coil is given by a dot product, between the magnetic field and the vector representing the area of the coil.
The latter vector has direction perpendicular to the plane in which the area of the coil is, and magnitude equal to the area of the coil. As in the attached image, the vector S is the vector respresenting the area of the coil.
Therefore, the flux will be maximum when the vector S is in the same direction as B, and will be zero when they are perpendicular.
Now, if <em>the coil is rotated so that the magnetic field is in the plane of the coil </em>then, the vectors S and B are perpendicualr, and there will not be net magnetic flux, that is, the flux will decrease.
Answer:
halve the slit separation
Explanation:
As we know that
In YDS experiment, the equation of fringe width is as follows
where,
D denotes the separation in the middle of screen and slits
d denotes the distance in the middle of two slits
And to increase the Δx we have to decrease the d i.e, the distance between the two slits
Hence, the first option is correct
Answer:
The total work done is 5997.6 J
Solution:
As per the question:
Mass of the bag, m = 60 kg
Vertical distance, h = 9 m
Mass lost, m' = 12 kg
To calculate the amount of work done:
Lost mass is proportional to the square root of the distance covered while lifting:
m' ∝
m' =
where
K = proportionality constant
12 = 3K
K = 4
Mass of the floor containing bag at a height h:
Work done is given by:
