An induced emf is produced inA. a closed loop of wire when it remains at rest in a nonuniform static magnetic field.B. a closed

Kazeer [188]

Answer:

C. a closed loop of wire moving at constant velocity in a nonuniform static magnetic field.

Explanation:

As we know by Faraday's law that rate of change in magnetic flux will induce EMF

so mathematically we can say that

$EMF = \frac{d\phi}{dt}$

so we will have

$\phi = B.A$

so EMF will be induced if the flux linked with the closed loop will change with time.

So here correct answer will be

C. a closed loop of wire moving at constant velocity in a nonuniform static magnetic field.

5.57 • Stay Dry! You tie a cord to a pail of water and swing the pail in a vertical circle of radius 0.600 m. What minimum speed

Stella [2.4K]

Answer:

The minimum speed of pail is 2.42 m/s.

Explanation:

Given that,

Radius = 0.600 m

We need to calculate the minimum speed of pail

Using centripetal force

$F=\dfrac{mv^2}{r}$

$mg=\dfrac{mv^2}{r}$

$v=\sqrt{gr}$

Where, v = speed

r = radius

g = acceleration due to gravity

Put the value into the formula

$v =\sqrt{0.600\times9.8}$

$v=2.42\ m/s$

Hence, The minimum speed of pail is 2.42 m/s.

Question 4 of 5

san4es73 [151]

B. Can be hurried up once you have it memorized.

Explanation:

A good stretching routine should not be hurried because it has been memorized. This is a bad stretching habit and should not be encouraged in daily routines.

Stretching helps to flex the muscle gently after a period of inactivity or over activity.
It ensures that our muscles are well straightened out and perfectly in shape.
A full body stretch should last a minimum of about five minutes.
Stretching helps to improve tissue elasticity and their flexibility
