Answer:
B, B (decreases, a clockwise)
Explanation:
Finally, the switch on the electromagnet is reopened. The magnitude of the external magnetic flux through the wire loop <u>decreases</u>, and there is <u>a clockwise</u>, current induced in the loop (as seen from the left).
Answer:
B will take 1.034 times the time of A from Boston to Hartford.
Explanation:
Let the distance from Boston to Hartford be S.
Person A drives at a constant speed of 55 mph for the entire trip,
Time taken by person A
Person B drives at 65 mph for half the distance and then drives 45 mph for the second half of the distance.
Time taken by person B
Ratio of time of arrival of B to A
B will take 1.034 times the time of A from Boston to Hartford.
In order to answer this, we would need to know
the half-life of ⁴⁰K. Perhaps when you look that up,
you'll be able to answer this on your own.
When a force of 8 N applied to a mass of 1 kg will cause it then mass will accelerate at the rate of
<u>Explanation</u>:
Given:
Force=8N
Mass=1kg
To find:
Acceleration rate=?
Solution:
Accrding to Netwon's second law of motion
Force = Mass x Acceleration
On substituting the values,
Solving the equation for Acceleration
Acceleration =8
Answer: μc
have: 2μF = F
the charge on this capacitor is (μc)
