A wire has a resistance of 8 Ω of 5cm^3 metal that has a resistivity of 9x10 ^-8 Ω⋅m. What should be its length and cross section?

What object a collides with object b and bounces back its final momentum is?

6–48 bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.
