Suppose that a ball is tossed at a wall; what is the probability that it will tunnel through the other side? the mass of the ball is 0.14 kg, the width of the wall is a = 0.2 m, and the who tossed the ball was deadly tired, that the ball is tossed only weakly at 1.0 m/s hint: before attempting this problem, make you considered problem 7. so problem 7 suppose that two operators p and q satisfy the commutation relation [p, q suppose that is an eigenfunction of the operator p with eigenvalue p. show that qw is also an eigenfunction of p, and find its eigenvalue

Eddy whose mass is 55kg climbs up the 1.50 meter high stairs in 2s.calculate eddy’s power rating

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

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
