Answer:
The wire now has less (the half resistance) than before.
Explanation:
The resistance in a wire is calculated as:
Were:
R is resistance
is the resistance coefficient
l is the length of the material
s is the area of the transversal wire, in the case of wire will be circular area (
).
So if the lenght and radius are doubled, the equation goes as follows:
So finally because the circular area is a square function, the resulting equation is half of the one before.
Energy of one photon = kinetic energy of photoelectron + work function energy of metal.
Intensity of radiation is proportional to the number of photons arriving per second
Answer:
I. Consumed energy = 4.5Kwh
II. Total cost = 3375 Dirhams
Explanation:
<u>Given the following data;</u>
Power = 1500W
Time = 3 hours
To find the energy consumption;
Energy = power * time
Substituting into the equation, we have;
Energy consumption = 1500 * 3
Energy consumption = 4500 watt-hour = 4.5Kwh (1 Kilowatts is equal to 1000 watts)
To find the total cost;
Daily cost = Energy consumption * cost
Daily cost = 4.5 * 25
Daily cost = 112.5 Dirham
Therefore, monthly cost = 112.5 * 30
Monthly cost = 3375 Dirham.
