Asquare loop of wire lies in the x, y plane with opposite corners at (0, 0) and (a, a), and is situated in a steady magnetic field b = b0(yz xˆ + xz yˆ + xy zˆ). if the loop moves with velocity v = vxˆ, calculate the motional emf e = h (v×b)· dl in terms of a, b0, and v. what is the direction of current flow in the loop?

What are the phases shown in a and d called?

Avehicle accelerates from 0 to 30 m/s in 10 seconds on a straight road

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
