  • The potential difference between two locations in an electric circuit is measured using a voltmeter.
  • If the electricity passes through the voltmeter it shows deflection.

<h3>What is the purpose of a voltmeter?</h3>
  • A voltage meter, usually referred to as a voltmeter, is a device that measures the voltage, or potential difference, between two points in an electrical or electronic circuit.
  • volts is the unit of voltmeter(volts, millivolts, kilovolts)

<h3>What is the explanation for the link between current and voltage?</h3>
  • Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant.

<h3>What is ohm's law in circuit?</h3>
  • V = IR, where V is voltage, I is current, and R is resistance, is known as Ohm's Law.
  • If you know the voltage of the battery in the circuit and how much resistance is in the circuit, you may use Ohm's Law to identify properties of a circuit, such as how much current is flowing through it.

A well hole having a diameter of 5 cm is to be cut into the earth to a depth of 75 m. Determine the total work (in joules) requi
guapka [62]

Answer:

total work is 99.138 kJ

Explanation:

given data

diameter = 5 cm

depth = 75 m

density = 1830 kg/m³

to find out

the total work

solution

we know mass of volume is

volume = \frac{\pi}{4} d^2 dx

volume = \frac{\pi}{4} d^2 1830 dx

so

work required to rise the mass to the height of x m

dw = \frac{\pi}{4} d^2 1830 gx dx

so total work is integrate it with 0 to 75

w = \int\limits^{75}_{0} {\frac{\pi}{4} d^2 1830 gx dx}

w = \frac{\pi}{4} × 0.05² × 1830× 9.81× (\frac{x^2}{2})^{75}_0

w = 99138.53 J

so total work is 99.138 kJ

sertanlavr [38]
Momentum is a protector the mass and the velocity of a moving object.
Momentum= mass*speed
For Car A: Mass:1,000 kilograms Velocity: 40 meters/second;
Momentum=1,000 kg*40 m/s
=40000kg.m/s
For Car B: Mass: 4,000 kilograms Velocity 10 meters/second;
Momentum=4000kg*10m/s
=40000kg.m/s
Both cars require the same amount of force to stop. This is because they have the same momentum.
