The voltage provided by the power supply = 20 V
<h3>Resistors in series </h3>
The Voltage across resistors in series in a circuit is equal to the sum of the voltage drops across each resistor.
Therefore for two resistors in series the total voltage provided by the power supply is equivalent to the summation of the voltage drops acroos each resistor ( i.e 10 V + 10 V = 20 V )
Hence we can conclude that the voltage provided by the power supply is 20 V

Answer:
about 0.8 times
Explanation: MARS is a planet named after a Roman God of War, it is the fourth planet from the sun and the Second smallest planet following Mercury.
The orbital Speed of a planet is the speed with which the planet uses to completely go round the Sun.
The orbital Speed of the Earth is 29.78kilmeters per Second.
The orbital Speed of Mar is 0.8*29.78kilometers per second/1
=23.824kilmeters per second.
Answer:
A- The ball has both kinetic and potential energy,
Explanation:
kinetic energy by virtue of its motion.
potential energy by virtue of its position. (It could roll off the edge of the tabel and convert gravity potential energy to kinetic energy)
Answer:
42.4m/s
Explanation:
To develop the problem it is necessary to apply the concepts related to thermodynamic work and Bernoulli's principle in which the behavior is described of a liquid moving along a stream.
The work of an incomprehensible liquid is given by the equation,
Where,
= Mass flow
= Specific Volumen
P = Pressure
Our values are given by,
= 2kW
Table 1 for saturated water in 10°C
We need to find the mass flow, then re-arrange for
To find the Spray velocity, we apply Bernoulli equation, because at the Nozzle there is not Work or Heat transfer related. Then,
Therefore the spray velocity is 42.4m/s
