As a tungsten light bulb ages, it gets dimmer due to a lower current in the filament. Which statement below describes a possible cause for this lower current? A. Tungsten evaporates from the filament, decreasing the cross-sectional area, thus decreasing the resistance.
B. Tungsten evaporates from the filament, decreasing the cross-sectional area, thus increasing the resistance.
C. Tungsten expands, increasing the length of the filament, thus decreasing the resistance
D. Tungsten shrinks, decreasing the length of the filament, thus increasing the resistance.

Give an example in which the electrical energy changes to light energy

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
