The value of specific heat for copper is390J/kg⋅C°,for aluminun is900J/kg⋅C°,and for water is4186J/kg⋅C° What will be the equilibrium temperature when a 215 g block of copper at 245 °C is placed in a 155 g aluminum calor ...
A light ray in air is incident on an unknown substance with an incidence angle of 39 degrees. If the light ray is refracted at an angle 20 degrees in the substance, what is the index of refraction of the substance?
Find the most probable code word in the case where the normalized likelihood is (0.2, 0.2, 0.9, 0.2, 0.2, 0.2, 0.2). Also find or estimate the marginal posterior probability for each of the seven bits, and give the bit-b ...
As shown in the figure, a small particle of charge q = -7.0 x 10 -6 C and mass m = 3.1 x 10 -12 kg has velocity vo = 11.2 x 10 3 m/s as it enters a region of uniform magnetic field. The particle is observed to travel ...
Investing $1000 at an annual interest rate of r%, compounded continuously, for 10 years gives you a balance of $B, where B = g(r). Give a financial interpretation of the statements: (a) g(5) ≈ 1649. (b) g (5) ≈ 165. What ...
SECTION ONE (a) In an Atwood Machine, suppose two objects of unequal mass are hung vertically over a frictionless pulley of negligible mass as shown below: Derive the expression for the magnitude of acceleration and Tens ...
A single-phase diode bridge is supplied by an a c source of 257 V, 60 Hz. This bridge in turn supplies a dc load of I dc = 60 A. Estimate the voltage drops due to (1) source with an inductance of 0.02 m H , (2) each dio ...
The point P moves around the circle of radius 5 shown in Figure 1.104. The angle θ, in radians, is given as a function of time, t, by the graph in Figure 1.105. (a) Estimate the coordinates of P when t = 1.5. (b) Describ ...
Two hockey pucks of equal mass approach each otherhead-onwith equal speeds of 8.7 m/s. They collide and one puck leaves the collision with a speed of 6.2 m/s. What is the speed of the other puck after the collision?
1. Why is 1=C(dV/dt) inconsistent with 1=dQ/dt If Q=CV Is used? Is C=dQ/dV consistent with 1=C(dV/dt) and 1=dQ/dt? Explain concisely, succinctly. 2. The n-channel Si MOS transistor switch In the DRAM (dynamic random acce ...
