You could probably expect normal plant growth, as a white light is similar to the sun in the respect that it contains all colors of the spectrum.
Explanation:
everything can be found in the picture
Answer:
a)![T = 2.9*10^{-5} N-m](https://tex.z-dn.net/?f=T%20%3D%202.9%2A10%5E%7B-5%7D%20N-m)
b) north edge will rise up
Explanation:
torque on the coil is given as
![T = NIABsin\theta](https://tex.z-dn.net/?f=T%20%3D%20NIABsin%5Ctheta)
where N is number of loop = 9 loops
i is current = 7.80 A
-B -earth magnetic field = ![5.00*10^{-5} T](https://tex.z-dn.net/?f=5.00%2A10%5E%7B-5%7D%20T)
A- area of circular coil
![A = \frac{\pi d^{2}}{4}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B%5Cpi%20d%5E%7B2%7D%7D%7B4%7D)
![A =\frac{\pi .14^{2}}{4}](https://tex.z-dn.net/?f=A%20%3D%5Cfrac%7B%5Cpi%20.14%5E%7B2%7D%7D%7B4%7D)
A =0.015 m2
PUTITNG ALL VALUE TO GET TORQUE
![T = 9*7.8*0.015*5*10^{-5} sin{90-56}](https://tex.z-dn.net/?f=T%20%3D%209%2A7.8%2A0.015%2A5%2A10%5E%7B-5%7D%20sin%7B90-56%7D)
![T = 2.9*10^{-5} N-m](https://tex.z-dn.net/?f=T%20%3D%202.9%2A10%5E%7B-5%7D%20N-m)
b) north edge will rise up
This question is personal preference... just answer with whatever YOU think, there probably isn’t s wrong answer if I’d guess.
Answer: E/4 ( one - fourth of it electric field)
Explanation:
The electric field of a point charge is given below as
E =kq/r²
E = electric field,
K = electric constant
q = magnitude of electric charge
r = distance between point charge and electric field.
It can be seen that only E and r are the only variable here and also, E is inversely proportional to r²
Which implies that
E = k/r² , k = E × r²
E1 ×(r1)² = E2 × (r2)²
Let E1 = E, r1 =1, r2 = 2 and E2 =?
Let us substitute the parameters
E × 1 = E2 × 2²
E × 1 = E2 × 4
E = E2 × 4
E2 = E/4
Which implies that the electric field at the second distance (r =4) is one fourth of the initial electric field.
