Problem 3-2: Multipacting Consider a parallel plate arrangement with electric field between the plates $\vec{E} = E_0 \sin(\omega t) \hat{z}$. Calculate the necessary gap voltage between the plates for a possibility of the 2<sup>nd</sup>-order multipacting to occur if the distance between the plates $d = 1$ cm, and the frequency of the oscillating field $f = 650$ MHz. USPAS 2025-RF Superconductivity: Homework #3 1/31/2025 $E_z = E_0 \sin(\omega t)$

As shown in the figure below, a water jet with diameter $D_1$ and velocity $u_1$ impacts on a plate with a hole with diameter $D_2$. Part of the jet passes through the hole with velocity $u_1$, while the remaining part of the jet is deflected in vertical direction (see figure below). Given $D_1 = 7cm$, $D_2 = 3cm$, $u_1 = 28m/s$, $u_2 = 22m/s$, and $\rho_w = 1000kg/m^3$, determine the horizontal force $F$ required to hold the plate. (Note: When reporting your answer, consider that the force towards right is positive and left is negative.) F = N

A person invested $6700 for 1 year, part at 4%, part at 9%, and the remainder at 12%. The total annual income from these investments was $659. The amount of money invested at 12% was $700 more than the amounts invested at 4% and 9% combined. Find the amount invested at each rate. The person invested $ \boxed{} at 4%, $ \boxed{} at 9%, and $ \boxed{} at 12%.

A funnel full of sand is placed at height $h = 10$ m above a scale. At $t = 0$ a hole is at the funnel and the sand begins to fall out on the scale at a rate of $\alpha = 25$ kg/s. The initial velocity of the sand grains when they leave the funnel is $v_0 = 14$ m/s and is directed downward. At a certain moment, the scale reading shows that the weight of the sand on it is $W = 780$ N. What is the real weight of the sand that is on the scale at his moment? Enter answer in units of Newton. (Remember that the reading on the scale is the normal force). Assume that each sand grain immediately loses all of its energy the moment it hits the scale, there is no situation when a grain of sand hits the scale and jumps up.
