Atub containing 58 kg of water is placed in a farmer's canning cellar, initially at 15 ∘c. on a cold evening the cellar loses thermal energy through the walls at a rate of 1200j/s. without the tub of water, the fruit would freeze in 4 h (the fruit freezes at −1 ∘c because the sugar in the fruit lowers the freezing temperature).

answer; equivalent to a one(1) horsepower motor;

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

that would be because of both gravity and friction. so     c

statement #3 on andre"s list is false.
