Ohm's law<span> states that the </span>current<span> through a </span>conductor<span> between two points is directly </span>proportional<span> to the </span>voltage<span> across the two points. Mathematically given by, R = V/I = 120/10 = 12 ohms or </span>Ω.

The formula is V= I x R

I being the current and R being the resistance. V being the voltage. 

So 120= 10xR

120/10 = R

R= 12

Hope this helped!

PLEASE PLEASE PLEASE A mad scientist places massive amounts of charge on basketball sized aluminum balls. The charge on the ball
bazaltina [42]

Answer:

4.2 x 10⁷N

Explanation:

Given parameters:

Charge on ball:

             q₁  = 3C

              q₂ = 14C

Distance between balls  = 9000m

Unknown:

Force acting on the two balls

Solution:

The force experienced by the two charges is given by coulombs law. It is mathematically expressed as;

                      F  = \frac{k q_{1} q_{2} }{r^{2} }

where k  = 9 x 10⁹Nm²/C²

           q is the charges

             r is the distance

Input the variables and solve;

                 

        F  = \frac{9 x 10^{9} x 3 x 14 }{9000}  = 4.2 x 10⁷N

What is the relationship between air pressure and air temperature?
LenKa [72]
The relationship between the two is that air temperature changes the air pressure. For example, as the air warms up the molecules in the air become more active and they use up more individual space even though there is the same<span> number of molecules. This causes an </span>increase<span> in the air pressure.</span>
