Answer:
As per faraday's law the rate of change in magnetic flux linked with a coil will induce EMF in the coil. It is given by
now here as we are closing the switch and then open it alternatively so it will change the value of current in the coil.
This change in current will change the magnetic flux in the coil due to which it will induce EMF in it.
Now by Lenz the the direction of induce current in the coil will always opposite to the causes due to which it is induced.
As we know that when switch is connected to flow the current the direction of induced current is in opposite to the current so that it will oppose the increasing value of current while when we open the switch the induced current is in direction of the current so that it will increase the value of decreasing current in the loop.
The induced emf is in the direction opposite to the direction of current.
Emf is the production of a potential difference in a coil as a result of changes in the magnetic flux passing through it.
When the flux coupling with a conductor or coil changes, electromotive Force, or EMF, is said to be induced.
The rate of change in magnetic flux linked to a coil will induce EMF in the coil, according to Faraday's law.
Now, when we alternately close and open the switch, the current in the coil will change.The magnetic flux in the coil will vary as a result of the change in current, resulting in EMF in the coil.
Now, according to Lenz, the direction of induce current in the coil will always be the polar opposite of the causes.
Hence the induced emf is in the direction opposite to the direction of current.

The best description of a grizzly bear’s habitat is:
A habitat is the natural surrounding or place where an organism lives, grows and competes with other organisms for resources. It is a physical area.
There are three major types of habitat which includes:
A grizzly bear is a subspecies of brown bear and is resident in the northern plains of America and their habitat is a physical location where they live.
Therefore, the correct answer is option D

Answer:
I found this question elsewhere on brainly and the answer was verified. Here it is!
Explanation:
Grizzly bear habitats is the habitat or the physical space where the bear lives. Grizzly bears can be found in many different habitats from dense forests to subalpine meadows, arctic tundra and open plains. We can also conclude that all of the bears live in grizzly bear's habitat in order to survive.
c. mass by area
b. volume by mass
d. area by mass
Answer:
a) 4.00 rad/s
b) 0.6 m/s, 0.3 m/s²
Explanation:
Given:
ω₀ = 0 rad/s
α = 2.00 rad/s²
t = 2.00 s
Find:
a) ω
b) v, a
a) ω = αt + ω₀
ω = (2.00 rad/s²) (2.00 s) + (0 rad/s)
ω = 4.00 rad/s
b) v = ωr
v = (4.00 rad/s) (0.15 m)
v = 0.6 m/s
a = αr
a = (2.00 rad/s²) (0.15 m)
a = 0.3 m/s²
