A light source radiates 60.0 W of single-wavelength sinusoidal light uniformly in all directions. What is the average intensity of the light from this bulb at a distance of 0.400 m from the bulb

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.

An electron with a charge of -1.6 × 10^-19 coulombs experiences a field of 1.4 × 10^5 newtons/coulomb. what is the magnitude of the electric force on this electron due to this field? a. 1.6 × 10^-3 newtons b. 1.4 × 10^24 newtons c. 2.2 × 10^-14 newtons d. 7.4 × 10^-13 newtons e. 4.5 × 10^14 newtons
