Answer:
Hans is more powerful
Explanation:
Power: This can be defined as the rate at which work is done or energy is used up.
The expression for power is given as,
P = E/t
P = mgh/t................. Equation 1
Where P = power, W = Work, t = time, m = mass, h = height, g = acceleration due to gravity.
Hans' power
P = mgh/t
Given: m = 100 kg, h = 2 m, g = 9.8 m/s², t = 3 s
Substitute into equation 1
P = 100(9.8)(2)/3
P = 653.33 W.
Frans' power
P' = mgh/t
Given; m = 200 kg, h = 5 m, t = 20 s.
P' = 200(5)(9.8)/20
P' = 9800/20
P' = 490 W
from the above,
since P>P'
Hence, Hans is more powerful

I hope it's helpful!
- The four inner plants have shorter orbits slower spin ,no rings ,and they are made up of rock and metal
- The outer plants are made up of hydrogen and helium, so they are called gas giants
Explanation:
hope it is the right answer
- 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.
