Explanation:
If the intensity of the yellow light increased, meaning more photons will strike the Potassium metal per unit area. This will cause more ejection of electrons from the metal and hence, the strength of current will also increase as we know that
I = Q/t, as the charge increase , the current will also increase.
Answer:
8 mm
Explanation:
From the information given:
The Ampere circuital law can be used to estimate the magnetic field strength at two points when the distance is less than the radius and when the distance is greater than the radius.
when the distance is less than the radius ; we have:
when the distance is greater than the radius; we have:
Equating both equations together ; we have :
where; d = radius of the wire and r = distance;
R = 8 mm
We know, x+y = 180
A.T.Q, x = 3y, y= x/3
substitute the value of y,
x+x/3 = 180
4x = 540
x = 540/4
x=135
The answer is 1.01 x 10^(-11) N. I arrived to this answer through calculating the GPEs of both balls. Bjorn's ball has a GPE of 1.402 x 10^(-11) N. Billie Jean's ball has a GPE of <span>2.503 x 10^(-11) N. I subtracted the two and I found that Billie Jean's tennis ball has a GPE of 1.01 x 10^(-11) more than Bjorn's tennis ball.</span>
Both the <span>telescope and the microscope are used to aid the naked eye to see things that a it normally cannot. Both also use lenses to magnify objects.
