A long straight wire lying along the x-axis carries a constant 5 A current along the positive x direction. A small 5mm diameter loop lies in the x-y plane centered at y = 2m. If the loop is suddenly stretched so that its area shrinks to zero in 0.2s, find the average induced emf in the coil assuming the B field is constant over its area. Draw a sketch showing the direction of the induced current

Apparent weight-stepped on scale at equator of this planet : You are an astronaut (m = 115 kg) and travel to a planet that is the same mass and size as Earth. This new planet, however, rotates more rapidly with a period of only 4 h. Considering the centripetal acceleration caused by this rotation, what is the ..
Density of the weight-compared with the density of water : A weight is attached to one end of a lightweight spring held at other end. When the weight comes to rest, the spring is stretched 20 cm beyond its natural length. In another condition the weight is completely immersed in water.
