Answer:
Part a)
ZERO
Part b)
N = 10 turns
Explanation:
Part a)
As we know that transformer is used to change the input voltage into required output voltage
Here this input and output is considered only when it will change with time as the whole concept is based upon Faraday's law where we need to change the flux with time.
So if we have input Source is DC source then output voltage will be zero as there is no flux change
Part b)
As we know by the principle of transformer
so total number of turns in secondary coil must be 10
Answer:
The correct option is: begins the hydrolysis of proteins in the stomach
Explanation:
Pepsin is a protease enzyme that is <u>synthesized by the stomach</u>. It is the main gastric enzyme that helps in the <u>digestion of proteins molecules </u>present in the food.
The pepsin enzyme catalyzes the<u> acid hydrolysis of the peptide bond in the proteins</u> at a very<u> low acidic pH of 1.5-2.0.</u>
This enzyme becomes <u>inactive at pH 6.0</u> and gets <u>fully denatured or irreversibly inactivated as the pH increases to 8.0</u>.
Complete question:
Driving in your car with a constant speed of v= 22 m/s, you encounter a bump in the road that has a circular cross-section, as indicated in the figure.
If the radius of curvature of the bump is 52 m, find the apparent weight of a 68-kg person in your car as you pass over the top of the bump.
Answer:
the apparent weight is 34 N
Explanation:
Given:
radius of curvature of the bump = 52 m
mass of the person = 68 kg
Apparent weight of the person due to centripetal acceleration which acts inward, is calculated as follows;
From Newton's second law of motion, apparent weight =
Therefore, the apparent weight is 34 N
Option C is correct. Frequency can be found by counting the number of troughs per second in a wave diagram.
<h3>What is the frequency?</h3>
Frequency is defined as the number of repetitions of waves occurring in 1 second. It can also be said that Frequency is defined as the number of cycles completed in 1 second.
Frequency is given by the formula as,
Hz.
Hence option C is correct. Frequency can be found by counting the number of troughs per second in a wave diagram.

At its maximum height <em>y</em>, the ball has zero vertical velocity. So we have
0² - (23 m/s)² = 2 * (-<em>g</em>) * <em>y</em>
where <em>g</em> = 9.80 m/s² is the acceleration due to gravity. Solve for <em>y</em> :
<em>y</em> = (23 m/s)² / (2 * (9.80 m/s²))
<em>y</em> ≈ 27 m
