Document Sharing Be sure to review Example 7.13 before attempting these problems. Part A A small box is released from rest at the top of a frictionless inclined plane as shown in (Figure 1). The horizontal surface at the base of the plane is rough and has a coefficient of kinetic friction $\mu_k = 0.5$. If $H = 30$ m, how far does the box slide on the rough surface before coming to rest, $d$? Express your answer with the appropriate units. Figure 1 of 1 d =

Suppose we have a 2D harmonic oscillator in the state |psi : a. What is the expectation value of the operator hat(L)_(z)=ℏ(hat(a)_(1)^(†)hat(a)_(1)-hat(a)_(2)^(†)hat(a)_(2)) ? b. What is the expectation value of the energy? Hint: Recall that hat(a)_(1)=(1)/(sqrt(2))(hat(a)_(x)-ihat(a)_(y)) hat(a)_(2)=(1)/(sqrt(2))(hat(a)_(x)+ihat(a)_(y)). 7.

n pipe is 18 in.. 7.34 What is the head loss at the outlet of the pipe that discharges water into the reservoir at a rate of 1.2 m³/s if the diameter of the pipe is 53 cm? Problems 7.33, 7.34 7.35 Fluid flowing along a pipe of diameter D accelerates around a disk of diameter d as shown in the figure. The velocity far upstream of the disk is U, and the fluid density is p. Assuming incompressible flow and that the pressure downstream of the disk is the same as that at the plane of separation, develop an expression for the force required to hold the disk in place in terms of U, D, d, and p. Using the expression you developed, determine the force when $U = 10 \text{ m/s}$, $D = 5 \text{ cm}$, $d = 4 \text{ cm}$, and $\rho = 1.2 \text{ kg/}m^3$. Assume $\alpha = 1.0$ at all locations.

Ramona is worried she won't do well on her test, so she engages in self-handicapping to manage the impressions others will have of her. There are two types of self-handicapping: behavioral self-handicapping and reported self-handicapping. Behavioral self-handicapping refers to when an individual intentionally engages in behaviors that may hinder their performance, such as procrastinating or not studying adequately. Reported self-handicapping, on the other hand, involves making excuses or providing explanations for potential poor performance in advance. An example of reported self-handicapping that Ramona might use is telling her friends that she didn't have enough time to study because she had to work late every night.
