An insulating rod having linear charge density = 52.0 µC/m and linear mass density = 0.100 kg/m is released from rest in a uniform electric field E = 135 V/m directed perpendicular to the rod. A vertical rod is labeled ", ". An electric field pointing from left to right, perpendicular to the length of the rod, is labeled vector E and is present on both the left and right sides of the rod.
(a) Determine the speed of the rod after it has traveled 2.50 m.
m/s

(b) How does your answer to part (a) change if the electric field is not perpendicular to the rod?

Identify the amplitude on the diagram and give the correct description. question 3 options: a because amplitude is the distance from wave crest to wave crest. b because the wavelength shows amplitude. c because amplitude is the distance between a crest (or trough) and rest. d because wavelength show amplitude.

Thomas his older brothers, who own a junk yard, on the weekends to earn extra money. he likes to them push broken-down cars to the back of the junk yard because it makes him feel strong. last saturday, they pushed three cars with different weights, and he noticed he used different amounts of force for each one. the cars were the following weights: white car: 2,700 kg red car: 1,500 kg blue car: 2,100 kg think about how much force is needed to move each car. which correctly lists the cars in order from the most to least amount of force needed to move them? a) white, blue, red b) blue, red, white c) red, white, blue d) white, red, blue
