An object with a mass of 70 kilograms is supported at a height 8 meters above the ground. what's the potential energy of the object with respect to the ground? a. 3,430 j b. 2,058 j c. 5,488 j d. 560 j

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
