Answer:
Induced emf,
Explanation:
It is given that,
Radius of the circular loop, r = 10.9 cm = 0.109 m
Magnetic field, B = 0.797 T
When released, the radius of the loop starts to shrink at an instantaneous rate of 107 cm/s,
Due to change in loop of the loop, an emf is induced in the loop. It is given by :
= magnetic flux
So, the emf is induced in the loop at that instant is 0.584 volts. Hence, this is the required solution.
<h3>The mass of the body is 7.38 kg</h3>
Given,
- Acceleration of the object = 3.4 m/s²
- Net force = 25.1 N
We need to find,
Using Newton's first law of motion .
- Force = Mass × Acceleration
➵ 25.1 = Mass × 3.4
➵ 25.1 ÷ 3.4 = Mass
➵ Mass = 7.38 kg
Answer:
2 N/m
Explanation:
Given that
The length of a wire, l = 15 m
Force on the wire, F = 60 N
Surface tension on the liquid, S = ?
The formula to solve this problem is given as
F = S * 2 L, where
F = force on the liquid
S = surface tension of the liquid
L= length of the wire
On substituting the values of each, we have
60 = S * (2 * 15)
S = 60 / 30
S = 2 N/m
Thus, we can say then, that the surface tension of the liquid is 2 N/m
Answer: increase the amount of work that is done?
Explanation:
I’m not entirely sure to be honest but I’ll just use my logic here. Machines are made to increase efficiency and production. Machines are made to save time and energy as a pose to human work. So several machines can mass produce a lot of things and keep business booming. I’m not very good at explaining things but I hope this makes sense eventually.
