To solve this problem we need to use the emf equation, that is,
Where E is the induced emf
I the current in the first coil
M the mutual inductance
Solving for a)
Solving for b) we need the FLux through each turn, that is
Where N is the number of turns in the second coil
Answer:
6 month interval
Explanation:
The distance to a nearby star in theory is more simple than
one might think! First we must learn about the parallax effect. This is the mechanism our eyes use to perceive things at a distance! When we look at the star from the earth we see it at different angles throughout the earth's movement around the sun similar to how we see when we cover on eye at a time. Modern telescopes and technology can help calculate the angle of the star to the earth with just two measurements (attached photo!) Since we know the distance of the earth from the sun we can use a simple trigonometric function to calculate the distance to the star. The two measurements needed to calculate the angle of the star to the earth caused by parallax (in short angle θ) are shown in the second attached photo.
So using a simple trigonometric function we can solve for d which is the distance of the earth to the star:
In the first attached photo a picture where r is the distance to the star and the base of the triangle is the diameter of the earth.

f) The speed when the particle is located 38.1 % of the amplitude away from the equilibrium position is:
This is difficult to explain, but it's hypotonic. HypERtonic is where there is where the cells shrivel up because there is more solute (salt is an example of a solute) on the outside, so the water rushes outward towards it and shrivels the cell. Plants like lots of water so they like to be hypotonic, and since you're adding pure H2O, there is no solute being added, so the solute is in the cell, causing the water to rush in. Isotonic is equal throughout the solution.
Answer:
D. move independently.
Explanation:
To be considered a living thing, an organism must be able to move independently.
