Answer:
Explanation:
Using the expression for the photoelectric effect as:
Also,
Applying the equation as:
Where,
h is Plank's constant having value
c is the speed of light having value
is the wavelength of the light being bombarded
is the threshold wavelength
is the kinetic energy of the electron emitted.
Given,
Thus, applying values as:
There are no appropriate units for power on the list you provided
Voltage-gated calcium ion channels open, and calcium ions diffuse into the cell
6.5454 m
Let the distance from the wire carrying 3 A current is x
Then the distance from the the carrying current 8 A is 24-x
We know that magnetic field due to long wire is given by
It is given that magnetic field is zero at some distance so
Here
So
v = 895 m/s
Time period is given as 39 Earth Days
now the radius of the orbit is given as
so the total path length is given as
now the speed will be given as
