5. An effort of 9.2 N was applied to a differential wheel and axle operating at 52 % efficiency to raise a load. If the machine has the following
measurements: radii of axles are 9.8 m and 12.2 m , radius of wheel, 30 m,
calculate the value of the load lifted.

What is the measurement of how fast an object moves relative to a reference point?

What would be the result of an alpha particle coming into a magnetic field? a) the alpha particle will stop moving. b) the alpha particle will reverse its direction. c) the alpha particle will be deflected in a curve path. d) the alpha particle will continue to travel in a straight line.

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.
