A uniform electric field has magnitude E and is directed in the negative x direction. The potential difference between point a (at x = 0.60 m) and point b (at x = 0.90 m) is 240 V. a. Which point, a or b, is at the higher potential?
b. Calculate the value of E.
c. A negative point charge q=−0.200μC is moved from b to a. Calculate the work done on the point charge by the electric field.

Tungsten-filament lightbulb emits light based on the temperature of the filament. which phenomenon does this demonstrate?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied. true or false
