A ball is dropped from a height of 10 feet. Each time it strikes the ground, it bounces up to 80% of the previous height.
a.What height will the ball bounce to after it strikes the ground for the third time?
b.How high will it bounce after it strikes the ground for the nth time?
c.How many times does the ball need to strike the ground before its bounce is less than one inch?
d.What total distance does the ball travel before it stops bouncing (This may be more difficult than it appears, so be careful)?
Consider unsteady diffusion across a membrane of thickness L. Initially, the concentration of solute in the membrane is zero. At time zero, the concentration at x=0 is raised to C0 and the concentration at x=L is maintained at zero.
Is the high carrier concentration in transparent conductors due to their ideal band structure or to the presence of defects and dopants. If two different materials but with the same work function are brought into contact, does band bending result.
A recording trace r(t) is definedas r(t) = s(t) + n(t), where s(t) =10sin(20?t) (i.e., a 10 Hz sine wave, given f= 2f) is the signal and n(t) = sin(120t) (i.e., the 60 Hz electromagnetic noise) the noise.
A 13,800/480 V three-phase Wye-Delta-connected transformer bank consists of three identical 100-kVA 7967/480-V transformers. It is supplied with power directly from a large constant-voltage bus.
1. Compare a script tool such as Matlab to a block tool like Simulink and how you can use them efficiently. 2. Convert the designed prototype filter to highpass filter with cutoff frequency f_C=10,000 Hz.
Build a home security system circuit using this program. The system must include 2 door sensors, 3 window sensors, 2 smoke detectors, 2 water leak sensors, and 2 motion detectors.
A hydroelectric dam has a penstock that discharges 10^5 kg/s of water. The head of the dam is 80m. a. compute the volume of the discharged water per second (flow rate). b. compute the power of the water entering the turbine
Show the truth table for the following circuits: a. A 3 input NAND GATE (Inputs are A,B, and C and the output is Q) b. A 3 input odd parity circuit. (Inputs are A,B, and C and the output is Q) c. A two bit adder with inputs (A1,A0 and B1,B0) and outp..
An electric flux of 151 Nm2/C passes through a flat horizontal surface that has an area of 0.715 m2. The flux is due to a uniform electric field. What is the magnitude of the electric field if the field points 10.3° above the horizontal
Consider the following signal y[n]; y[n] = X1[n+3] * X2[n] The signals X1 and X2 are defined as X1[n]=((1/2)^n) u[n] X2[n]= ((1/3)^n u[n] Determine the Z transform of y[n].
Line A extends from (2,2, 0) to (-2, 2, 0) and Line B extends from (2, -2, 0) to (-2, -2, 0). Each has a linear charge density l = 1 nC / m. You want to calculate the magnitude and direction of the electric field due to the two line charges for al..
build a cicuit that must be able to operate a 3 amp load of the LED while being able to operate at voltages around 3V or 6V. It must be able to keep the LED on constantly while also being able to pulse the LED.
