Find the total amount of heat Q lost through a wall 10' by 18', with R value from q. 1. Inside temperature is 70°F while outside is 45°F.

Two resistors, with resistances R1 and R2, are connected in series. R1 is normally distributed with mean 65 and standard deviation 10, and R2 is normally distributed with mean 75 and standard deviation 5. a. What is the probability that R2 > R1?

When a gas in a piston cylinder device is compressed, and as a result temperature rises. This process is a work interaction. a) True b) False

Consider a 1000-W iron whose base plate is made of 0.5-cm-thick aluminum alloy 2024-T6 (rho = 2770 kg/m3 and cp = 875 J/kg·°C). The base plate has a surface area of 0.03 m2. Initially, the iron is in thermal equilibrium with the ambient air at 22°C.

Madison and Oxford are the same distance from the equator and they are both near the ocean. Use the information on the map to answer these questions: How does the air temperature of Madison compare to the air temperature of Oxford? Why?

Write the definition of a method named add that receives a reference to a Scanner object associated with a stream of input consisting of integers only. The method reads all the integers remaining to be read from the stream and returns their sum.

How are fluids distributed and transported in a fluid power system?

The sliders A and B are connected by a light rigid bar of length l = 20 in. and move with negligible friction in the slots, both of which lie in a horizontal plane. For the position where xA = 16 in., the velocity of A is vA = 3 ft/sec to the right.

Two parallel Rivers (A and B) are separated by confined and unconfined aquifer estimate the RATE of seepage of river A to River B per unit length of the rivers
