An object gains 10 joules of potential energy as it is lifted vertically 2.0 m. If a second object with one-half the mass is lifted vertically 2.0m, the potential energy gained by the second object will be a. 10j
b. 20j
c. 5.0j
d. 2.5j

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

i believe the answer is true.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4
