attempt on #4 a. yes matter is not transferable b. no matter is transferred c. yes, no interaction d. yes adiabatic does not conduct heat

i really need help with my homework if people can help lead me to the answer it would be really helpful. so far i was only able to do number 1 1) If 2.00 mol of an ideal gas, initially at 1.53 atm and 280 K, is allowed to expand isothermally under a constant external pressure of 0.920 atm...

Homework Statement A prescription for a corrective lens calls for +1.50 diopters. The lensmaker grinds the lens from a "blank" with n = 1.46 and a preformed convex front surface of radius of curvature of 19.0 cm. What should be the radius of curvature of the other surface? Homework...

anyone?

nope just basic energy and voltage equations

Homework Statement A lightning flash transfers 2.5 C of charge and 3.3 MJ of energy to the Earth. (a) Across what potential difference did it travel? 1.32 MV (b) How much water could this boil and vaporize, starting from room temperature? Homework Equations need...

so the energy of the capacitor should be (35000000 * 18.585) 650475000 J??

i will. to find energy you do w =Vq right?

thanks. i don't know why put my teacher has it like that on his equation sheetCalculate the charge stored in the "capacitor" = 18.585 Calculate the energy stored in the "capacitor" = should be 35000000 * 18.585 right?

Homework Statement In lightning storms, the potential difference between the Earth and the bottom of the thunderclouds can be as high as 35,000,000 V. The bottoms of the thunderclouds are typically 1500 m above the Earth, and can have an area of 90 km^2. For the purposes of this problem...

i guess so

((8*9.8)/2)+(6.5*.28)

An 8.0-kg hanging block is connected by a string over a pulley to a 6.5-kg block sliding on a flat table. If the coefficient of sliding friction is 0.28, find the tension in the string. is the answer 41.02 N ?

thz i figured it out it sid make up a functions but thanks anyway
