A mechanical aim rotates in the vertical plan about point O. The slider P (m = 2 kg) is drawn toward O with a constant speed (?̇) of 0.5 m/s through the rough slot (friction coefficient µ = 0.1) by pulling on the free end E of the cord. At the instant when r = 0.25 m, the arm is rotating with a constant speed (?̇) of 10 rad/s in the clockwise direction. When the slider is oriented at an...

A m = 4.10 kg block is attached to a vertical rod by means of two strings. When the system rotates about the axis of the rod, the strings are extended as shown in the figure, where L is 1.30 m and h is 1.60 m, and the tension in the upper string is 98 N. How many revolutions per minute does the system make?

10. Consider the simplified scenario for genetic determinants of height in humans, where there are three genes (A/B/C) with varying numbers of alleles (3/3/2) affecting height, and with different effects in males and females. (Assume additive contributions, thus the effect of having genotype A1A2 is +0.1” + +0.2” = +0.3”). Average height for men and women is 69” and 64”.

Can a system have negative potential energy? No, because a negative potential energy is unphysical. No, because the kinetic energy of a system must be equal to its potential energy. Yes, as long as the total energy remains positive. Yes, as long as the total energy remains negative. Yes, because the choice of the zero of potential energy is arbitrary.

Lennard–Jones potential diagrams, also called intermolecular potential energy diagrams, illustrate the relationship between the potential energy of a molecule as the distance between the two nuclei changes. Select all of the true statements regarding Lennard–Jones potential diagrams from the list below. Once the attractive forces are greater than the repulsive forces, the outer orbitals are able to overlap, thereby allowing a bond to form. Once a balance is found between the attractive and repulsive forces, the outer orbitals are able...
