Its wintertime and you are in need of portable electrical heater for your room and you are comparing two different products. The first heater has metal grills made of aluminum and has dimensions of 0.75 [m] x 0.05 [m] x 0.01 [m] while the second heater has metal grills made of iron and has dimensions of 1.00 [m] x 0.03 [m] x 0.01 [m]. You wish to heat your room from 10 degrees Celsius to a nice toasty 28 degrees Celsius and your wall outlet provides 120 [V].
A)What is the resistance of the aluminum and iron heater at 28 degrees Celsius?
B)What is the current for the aluminum and iron heater operating at 28 degrees Celsius?
C)If you wish to operate your heater for 4 hours and the cost of electricity is $0.12 per kilowatt-hour, which heater has cheaper operational costs?
Computer chips are etched on circular silicon wafers of thickness 0.60 mm that are sliced
from a solid cylindrical silicon crystal of length 30 cm. If each wafer can hold 100 chips,
what is the maximum number of chips that can be produced from one entire cylinder?
Collectible coins are sometimes plated with gold to enhance their beauty and value. Consider a commemorative quarter-dollar advertised for sale at $4.98. It has a diameter of 24.3 mm, a thickness of 1.78 mm, and is completely covered with a layer of pure gold 0.214 µm thick. The volume of the plating is equal to the thickness of the layer multiplied by the area to which it is applied. The patterns on the faces of the coin and the grooves on its edge have a negligible effect on its area. Assume the price of gold is $14.1 per gram.
(a) Find the cost of the gold added to the coin.
(b) Does the cost of the gold significantly enhance the value of the coin?
Yes or No
Explain your answer.

- A quality assurance engineer at a frying pan company is asked to qualify a new line of nonstick-coated frying pans. The coating needs to be 1.00 mm thick. One method to test the thickness is for the engineer to pick a percentage of the pans manufactured, strip off the coating, and measure the thickness using a micrometer. This method is a destructive testing method. Instead, the engineer decides that every frying pan will be tested using a nondestructive method. An ultrasonic transducer is used that produces sound waves with a frequency of f = 25 kHz. The sound waves are sent through the coating and are reflected by the interface between the coating and the metal pan, and the time is recorded. The wavelength of the ultrasonic waves in the coating is 0.076 m. What should be the time recorded if the coating is the correct thickness (1.00 mm)?arrow_forwardGrains of fine California beach sand are approximately spheres with an average radius of 50 pm and are made of silicon dioxide, which has a density of 2.6 x 103 kg/m3 What mass of sand grains would have a total surface area (the total area of all the individual spheres) equal to the surface area of a cube 0.8 m on an edge?arrow_forwardA deep-sea diver is suspended beneath the surface of Loch Ness by a cable of length h= 100 mthat is attached to a boat on the surface (Figure 1).
