The final speed of the orange is 7.35 m/s
Explanation:
The motion of the orange is a free fall motion, since there is only the force of gravity acting on it. Therefore, it is a uniformly accelerated motion with constant acceleration towards the ground. So we can use the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time elapsed
For the orange in this problem, we have
u = 0 (it is dropped from rest)
is the acceleration
Substituting t = 0.75 s, we find the final velocity (and speed) of the orange:

a) Current for long straight wire
b) Current at the center of the circular coil
c) Current near the center of a solenoid
Explanation:
⇒ Magnetic Field due to long straight wire is given by (B),where
Plugging the values,
Conversion ,and
⇒Magnetic Field at the center due to circular coil (at center) is given by,
So
⇒Magnetic field due to the long solenoid,
Then
So the value of current are ,
and
respectively.
