Aparticle is confined to the x-axis between x = 0 and x = 1 nm. the potential energy u = 0 inside this region and u is infinite outside. what is the longest possible de broglie wavelength for the particle?

a. infinite
b. 1 nm
c. 2 nm
d. zero
e. 0.5 nm

More solar radiation is absorbed by earth’s surface than by

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.

Agirl throws a ball. if the ball's acceleration is 12 m/sec/sec and its mass is 0.5 kg, how much force did the girl apply to the ball?
