In the figure, a long straight wire carries a current I1 = 42.1 A and a rectangular loop carries current I2 = 16.2 A. Take a = 1.43 cm, b = 9.67 cm, and L = 40.5 cm. What is the magnitude of the net force on the loop due to i1?
in this problem we consider two charges placed on the y-axis and calculate the resulting potential for points on the
A cargo helicopter, descending steadily at a speed of 3.6 m/s, releases a small package. how long does it take for the package to reach the ground
An ideal gas with =1.4 occupies 3.0L at 300 K and 100kPa pressure and is compressed adiabatically until its volume is 2.0 L. It's then cooled at constant pressure until it reaches 300 K, then allowed to expand is thermally back to state A.
