The flan is elastic, but it falls apart if the height of the flan is compressed by more than 20% of its original height. If you were to decorate your flan with fruit on top, what is the maximum mass of fruit that the flan can hold before it falls apart? Area = 0.0016 m^2 L = 0.022 m The flan, after it has cooled down from the oven, has a height Lo = 0.022 m. When a weight of 0.220 kg is applied over the total area A = 0.0016 m^2, the flan deforms, and the height of the flan goes down by 4L = 0.003 m. Use g = 10 m/s^2 as the gravitational constant to calculate the force exerted over the flan.
Use the result of Ex. 5.6 to calculate the magnetic field at the center of a uniformly charged cylindrical shell, of radius R, of length L and linear charge density A, spinning at a constant angular velocity ω. What happens when L becomes infinite?
1. Consider the analog signal $x_a(t) = 3 cos 2000pi t + 5 sin 6000pi t + 10 cos 12000pi t$ (a) What is the Nyquist rate for this signal? (b) Assume now that we sample this signal using a sampling rate $F_s = 5000 frac{samples}{sec}$. What is the discrete-time signal obtained after sampling? (c) What is the analog signal $y_a(t)$ that we can reconstruct from the samples if we use ideal interpolation? 2. An Analog signal has frequency components at 1 kHz, 12 kHz, 28 kHz, and 30 kHz. The signal is sampled at a sampling rate of 20 kHz, then the resulting signal goes through an ideal reconstruction low pass filter (LPF) with a cutoff of 9 kHz. What frequencies are present in the output?
On a system using either M:1 or 1:1 mapping, user level threads reflect both the scheduling of the user thread library and this of the kernel. ? True O False Question 5 2.5 pts Assume a 2 way threaded multi-core processor with 6 cores. You are allowed to generate UP TO 80 threads in total, including hardware and software threads for applications that are heavy/intense in computations for 2 cases: Case 1) the threads get constantly their operands through an external process through pipes, Case 2) the threads have a list of the operands stored in their private stack. Answer with a number: 1-80: How Many USER threads is it best to use in case 1 ? 36 ? 18 ? 24 ? 12 ? 48 ? 6
A 1350-kg car is traveling with an initial speed of 24.5 m/s. Determine the car's speed after $-1.85 \times 10^3$ J of net work is done on the car. m/s Question 5.2b: A 14.6-kg box is sliding across a horizontal floor. It has an initial speed of 1.30 m/s and the only force acting on it is kinetic friction with magnitude $f_k = 2.95$ N. Determine the distance the box will travel before coming to rest. m
