Explanation:
Answer:
u= 187.61 ft/s
Explanation:
Given that
g= - 32 ft/s²
The maximum height ,h= 550 ft
Lets take the initial velocity = u ft/s
We know that
v²=u² + 2 g s
v=final speed ,u=initial speed ,s=height
When the object reach at the maximum height then the final speed of the object will become zero.
That is why
u²= 2 x 32 x 550
u²= 35200
u= 187.61 ft/s
That is why the initial speed will be 187.61 ft/s
Answer:
Approximately 18 volts when the magnetic field strength increases from to at a constant rate.
Explanation:
By the Faraday's Law of Induction, the EMF that a changing magnetic flux induces in a coil is:
,
where
- is the number of turns in the coil, and
- is the rate of change in magnetic flux through this coil.
However, for a coil the magnetic flux is equal to
,
where
- is the magnetic field strength at the coil, and
- is the area of the coil perpendicular to the magnetic field.
For this coil, the magnetic field is perpendicular to coil, so and . The area of this circular coil is equal to .
doesn't change, so the rate of change in the magnetic flux through the coil depends only on the rate of change in the magnetic field strength . The size of the magnetic field at the instant that will not matter as long as the rate of change in is constant.
.
As a result,
.
