Can anyone please describe the motion qualitatively? I cannot visualize this problem. After the blow, the spring is maximally compressed and the block on the right moves to the right, away from the wall. I know that the left mass leaves the wall the first time that the right mass has its maximum...
Homework Statement
To withstand the harsh weather of the Antarctic emperor penguins huddle in groups. Assume that a penguin is a circular cylinder with a top surface area of 0.34m2 and a height of 1.1m. If penguins huddled closely to form a huddled culinder with a top surface area of Na and...

In a problem it states that:
A 10.71 V battery is connected to a resistive strip that consists of three sections with the same cross-sectional areas but different conductivities.
In the solution to the problem it stipulates that the current density of the three sections are equal. Where in...
Homework Statement
If an uncharged parallel-plate capacitor (capacitance C) is connected to a battery, one plate becomes negatively charged as electrons move to the plate face (area A). The depth d from which the electrons come in the plate in a particular capacitor is plotted against a range...
The problem is this:
a 0.250 kg block of cheese lies on the floor of a 900 kg elevator cab that is being pulled upward by a cable through distance d1 = 2.40 m and then through distance d2 = 10.5 m. (a) Through d1, if the normal force on the block from the floor has constant magnitude FN = 3.00...
