Ablock is suspended from the ceiling by a long, thin strip of tungsten metal. the strip behaves as a spring. to produce a 0.25m horizontal deflection of the block, a force of 6.5 n is required. calculate the spring constant for the tungsten strip.

Which type of wave can travel without a medium

=force × distance a. work b. velocity c. pressure d. momentum

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v
