What is the thermoelectric difference of chromel at 400°C relative to platinum?
The contract size for platinum futures is 50 troy ounces. Suppose you need 400 troy ounces of platinum and the current futures price is $1,255 per ounce. How many contracts do you need to purchase? How much will you pay for your platinum? What is your dollar profit if platinum sells for $1,295 a troy ounce when the futures contract expires? What if the price is $1,200 at expiration? (A negative value should be indicated by a minus sign. Do...
The difference between platinum and gold pricing of tickets for Buffalo Sabres games was mainly based on: Wednesday games were all platinum games Sabres win percentage was the key determinant with platinum games occuring after Sabres wins. Gold games were for divisional games and platinum games were for inter-conference games Platinum games were reserved for rivals like the Maple Leafs when the game was played on the weekend
A 400-pF capacitor carries a charge of 2.5*10-8 C. What is the potential difference across the plates of the capacitor?
What is the difference between an absolute and a relative link? What are the advantages and disadvantages of using each type? Can you give an example of how you would use an absolute link and a relative link on a website? I look forward to your reply.
Explain the difference between accuracy and precision. What is the difference between absolute vs. relative uncertainty? What are the equations commonly used to calculate these terms?
both questions 21. What is the relative change in intensities if the difference in the signals - is (a) 10 dB (b) -3 dB (c) 5 dB 22. A wave's intensity is 50 W/cn. There is a change of +10 dB. What is the final intensity?
What is the relative growth difference in rooms revenue for a 205-room hotel that experienced an occupancy in 2006 of 80.4% and 82.7% in 2005? The hotel achieved an average room rate in 2006 of $198.36 and $179.55 in 2005. Round your answer (%) to one decimal point. Relative growth difference = ___ %
A 12.88-g block of solid platinum at 61.54 °C is immersed in a 21.78-g pool of liquid ethanol with a temperature of 13.43 °C. When thermal equilibrium is reached, what is the temperature of the platinum and ethanol? Specific heat capacities: platinum = 0.133 J/g °C; ethanol = 2.44 J/g °C
A platinum resistance thermometer has a re- sistance of 200 ohms. A platinum resistance thermometer has a resistance of 200 ohm when placed in an ice 0 degree C bath and 290.8 Ohm when immersed in a crucible containing a melting substance. What is the melting point of the substance? The temperature coefficient of the platinum is 0.00392 (degreeC)^-1 . The resistor was calibrated at a temperature of 20 degree C. Answer in units of degree C. A platinum resistance...
Please explain what "percentage difference" and "relative standard error" values show in regard the collected data in lab? If they are equal, or if one value is higher than the other, what that means? (percentage difference is the difference divide by average times 100 and relative standard error is standard error divide by mean times 100.) Thanks.
