What is the horsepower of a 1400kg car that can go to the top of a 350.0 m- hill hill in exactly 1.00 minute?

109.4hp

Explanation:

107.24hp

Explanation:

From the question given, we obtained the following:

m = 1400kg

h = 350m

g = 9.8m/s2

t = 1min = 60secs

Power = mgh/t

Power = (1400 x 9.8 x 350)/60

Power = 8 x 10^4watts

Recall

746watts = 1hp

8 x 10^4watts = 8 x 10^4/746

Power = 107.24hp

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

this means that the temperature of both substances will be equal
