<h3><u>Answer;</u></h3>
<em>The voltage is zero</em>
<h3><u>Explanation;</u></h3>
- <em><u>Voltage is the potential difference between two points in a circuit or the electromotive force in a given circuit and is expressed in volts (V). </u></em>
- Voltage is measured by a device called voltmeter that is always connected in parallel with the current source.
- <em><u>When voltage is measured between two points on a wire in a circuit with zero or no resistance in between the two points then the voltage will be zero</u></em><em>. </em>From the ohm's Law, voltage is given the product of resistance and current and thus if the resistance is zero then the voltage will be zero.
The pressure is 5000 Pa
Explanation:
The pressure exerted by a force on a surface is given by the equation:
where
p is the pressure (measured in Pascal, Pa)
F is the magnitude of the force
A is the area of the surface on which the force is exerted
In this problem, we have:
F = 2 N
Substituting into the equation, we find the pressure:

Answer:
273 Kelvin
Explanation:
If -273 Celsius is 0 Kelvin, then 273 Kelvin will be 0 Celsius.
a.) Relative velocity = velocity of car B - velocity of car A
= 19 - 14
= 5 m/s
