You have forgotten to switch off a 2000W electric hot plate in the kitchen. Estimate the temperature of the plate when you discover it next morning assuming that the plate is well isolated from the rest of the stove and it is black enough that its emissivity can be considered to be unity. (s = 5.67x 10^-8 J/(s m^2 K4)

Ameter stick is pivoted at the 0.50-m line. a 3.0-kg object is hung from the 0.15-m line. where should a 5.0-kg object be hung to achieve equilibrium (the meter stick oriented horizontal and motionless)?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
