Answer:
18
Explanation:
<em>V = voltage
</em>
<em>I = current </em>
<em>R = resistance</em>
V = IR is the equation to find out the Voltage of an item so if we move around the equation so we are trying to resistance it would become R = V/I.
V = IR
R = V/I
R = 9/0.5
<u>R = </u><em><u>18</u></em>
Answer:
Explanation: work equals force times distance so 400x4=1600 joules
It is 356.5 just subtracts because it’s opposite
KE = 0.5mV^2 = 0.5 * 0.0025 * (20)^2 =
<span>0.5 Joules.</span>
You use a force meter to measure newtons
