Recall this formula for a device operating in a direct current circuit:
P = IV
In this equation, P stands for the power emitted by the device, I signifies the current passing through the device, and V represents the voltage drop across it.
Using ampere for current and volt for voltage means that multiplying current by voltage gives you power measured in watts.
Answer:
Explanation:
at 23 degrees Celsius, the diameter measures 4.511 mm
GIVEN DATA:
diameter of hole = 4.500 mm
T_1 = 23.0 degrees Celsius
T_2 = - 78.0 degrees Celsius
the expansion coefficient of aluminum is 2.4*10^{-5} (degrees Celsius)^{-1}
the diameter at 23 degrees Celsius is stated as


= 4.511 mm
the diameter of the rivet after temperature change is given as



= 0.4511 cm
