a) (5 points) Calculate the energy absorbed by a stationary wall when a car weighting 100 kg impacts at 100 km/hr. b) (5 points) A weight of 100 kg is dropped from a height of 3m. Estimate the heat released upon impact.
Calculate the amount of water that must be fed into an heat exchanger that cools 100 kg/h of tomato sauce from 90 to 20°C. The tomato sauce contains 40% solids. The temperature of the water leaving the heat exchanger must not exceed the entering water temperature by 10°C. mw = 531.82 kg/h
Use the work-energy theorem to calculate the minimum speed v
that you must give the box at the bottom
of the incline so that it will reach the skier.
Constants Part A You are a member of an alpine rescue team and must get a box of supplies, with mass 2.00 kg, up an incline of constant slope angle 30.0 ° so that it reaches a stranded skier who is a vertical distance 2.50 m above the bottom of the...
Example 1 Calculate the energy transferred by photon (Eph or E) for a monochromatic radiation with wavelength of: Photon Energy hc E = a h is planck constant, C velocity of light in vaccum (m/s) and is wavelength of radiation (m) 0.4 um 1.08 um 1.8 um a) b) c) [Assume that h = 4.1358 x 10-15 eV and C = 3 x 108 m/s] Example 2 Consider a 100 cm2 photovoltaic cell with reverse saturation current lo= 10-12 A/cm2....
I was wondering if i could get help with these three quesions, i
missed the day they went through this
0/4 points Ask Your Teacher My Notes 7. Previous Answers Use the Rydberg equation to calculate the wavelength (in Ä) of the photon absorbed when a hydrogen atom undergoes a transition from n = 1 to n = 2. (Report your answer to at least 3 significant figures.) Your response is off by a multiple of ten. Å + -/4...

4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...
Midwestern Hardware must decide how many snow shovels to order for the coming snow season. Each shovel costs $15.00 and is sold for $29.95. No inventory is carried from one snow season to the next. Shovels unsold after February are sold at a discount price of $10.00. Past data indicate that sales are highly dependent on the severity of the winter season. Past seasons have been classified as mild or harsh, and the following distribution of regular price demand has...
7. Two light bulbs with ratings of 40 W and 100 W are plugged into sockets supplying 110 V. A) Calculate the resistance of each. Which has more resistance? The more resistance. (Notice that voltage is fixed) W bulb has B) If the 100 W bulb is operated continuously for 2 full days and electric energy costs $0.12 per kWh, how much does it cost? Convert W to kW multiply by the number of hours to get kW.h multiply by...
Assignment 9 If you run around a half-mile track twice in 20 minutes a. What is the total distance traveled? b. What is the speed in mi/hr (show work)? c. What is the total displacement? d. What is the velocity in mi/hr? You travel east 2 miles and then turn to the north and walk another 3 miles. What is your displacement (show work, make sure to show the direction as well)? You travel 6 miles at 40 degrees. How...
