The voltage drop across an electrical resistor is 10 volts and the current through it is 1 ampere. Heat is dissipated from the resistor to the surrounding air according to the relation Q =-h(T-T amb) is the ambient air temperature,25C; T is the temperature of the resistor, and h, the heat transfer coefficient, is equal to 0.2 J/Ks. Compute the steady-state temperature of the resistor, that is, the temperature of the resistor when the energy loss from the resistor is just equal to the electrical energy input.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
