What is the magnetic flux through the coil in the direction of the +x+x-axis (Hint: The identity sin(A+B)+sin(A−B)=2sinAcosBsin⁡(A+B )+sin⁡(A−B)=2sin⁡Acos⁡B may prove helpful.)

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg. how much energy e must be supplied to the device? express your answer in joules.

What is a subatomic particle with a negative charge and very little mass?
