Given a wire with a cross section of .45cm^2, a length of 3cm, and an internal resistance of 3 ohms, show your 5 steps to solve
Gre4nikov [31]
Resistance ∞ (proportional) length 
resistance ∞ 1/ area

therefore, 
(the constant that we take is known as the resistivity)

resistance =  (resistivity*length )/ area
 resistivity = (resistance * area ) / length
                  = (3 * 45) / 3 =    135/3 = 45 Ωm

in short your answer is 45 Ωm

Ramas weight is 40 kg. She is carrying a load of 20 kg up to a height of 20 m. What work does she do? What work does she do?
Taya2010 [7]

Answer:

The work done by Ramas is 3920 N.

Explanation:

Given;

mass of the load lifted by Ramas, m = 20 kg

height through which the load is lifted, h = 20 m

The work done by Ramas is equal to gravitational potential due to the height in which the load is lifted.

W = PE = mgh

where;

g is acceleration due to gravity = 9.8 m/s²

W = 20 x 9.8 x 20

W = 3920 N.

Therefore, the work done by Ramas is 3920 N.

Explain why the reflection of light off ground glass changes from diffuse to specular if you spill water on it
Basile [38]
Because when you spill water on it, the reflection comes from the surface of the water, not the ground glass.
