Answer:
Explanation:
It is given that,
Mass of the loop, m = 10 g = 0.01 kg
Resistance of the loop, R = 0.02 ohms
Dimension of square loop, 7 cm × 7 cm
Area of the loop,
At time t = 0 s, the magnetic field increases from 0 to 1 T in 0.01 s
(a) Due to change in magnetic field, an emf is induced in the loop. Using the formula for induced emf as :
Now using Ohm's law to find the induced current in the loop. It is given by :
I =24.5 A
(b) A magnetic force acting on the loop is given by :
F = 0.8575
Since,
v = 0.8575 m/s
Hence, this is the require solution.
It’s definitely the 3rd one
Answer:
Time = 801.802 secs.
Explanation:
Speed can be defined as the rate of change in the magnitude of distance with respect to time. It is a scalar quantity because it only has magnitude but no direction.
Given the following data;
Average speed = 11.1m/s
Time =?
Distance = 8900m
Making time (t) the subject of formula, we have;
Time = 801.802 secs.
<em>Hence, the time the biker takes to cover the segment is 801.802 seconds. </em>

Just because there is more mass in a certain substance doesn’t mean it’s density will change. In this case, water, will not change density simply because there is more of it. I.e the ocean. The bottom of the ocean may have more pressure to it because of the weight of the water above it but if you were to take a cup of it and take it to the surface it wouldn’t sink.
