Answer:
The resistance of the heater is 44 ohms.
Step-by-step explanation:
Given that,
Voltage of electric heater, V = 440 volts
Current drawn by the heater, I = 10 A
We need to find the resistance of the heater. It is a case of Ohm's law. Its mathematical form is given by :
R is resistance of the heater
So, the resistance of the heater is 44 ohms. Hence, this is the required solution.
The car can travel 1120 miles because 20 times 56 equals 1120
Answer:
2827.4
Step-by-step explanation:
V = πr2h this is the equation that can be used for these problems.
V= π(10)2(9)
the radius is 10 because the diameter is 20. Divide the given diameter by 2 to find the radius.
