Answer:
a
The magnetic field strength is 
Explanation:
From the question we are told that
The length line above the ground is 
The current of the line is 
The voltage of the line is 
Generally magnetic field strength is mathematically represented as
Where 
is the permeability of free space 
![= (2.0*10^{-7})[\frac{200}{20} ]](https://tex.z-dn.net/?f=%3D%20%282.0%2A10%5E%7B-7%7D%29%5B%5Cfrac%7B200%7D%7B20%7D%20%5D)
Earths magnetic field is approximately given as 
So the percentage would be
%
a. reflect (I found this using prior knowledge and process of illumination it can't be absorb cuz you wouldn't see anything it can't be refract because it doesn't reverse the image and it isn't transmit )
Answer:
The mass goes down
Explanation:
Because mass is the quantity of matter contained in a substance And Volume is the space occupied by a substance. So when the volume is less the mass decreases
Answer:
126.99115 g
Explanation:
50 g at 90 cm
Stick balances at 61.3 cm
x = Distance of the third 0.6 kg mass
Meter stick hanging at 50 cm
Torque about the support point is given by (torque is conserved)
The mass of the meter stick is 126.99115 g
Answer:
New moon
Explanation:
A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth's surface.
