What is the weight of the object? an object pulled to the right by two forces has an acceleration of 2.5 m/s2. the free-body diagram shows the forces acting on the object. o 50 n o 98 n o 313 n o 490 n f = 50 n f = 75 n

Atomic nuclei of almost all elements consist of

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

Does heating a metal wire increase or decrease its electrical resistance? why?
