Four weightlifters a through d enter a competition. their mass and distance that each lifts are shown in the table.

weighlifter mass(kg) distance(m)
a 100.0 2.25
b 150.0 1.76
c 200 1.50
d 275 1.25

which weightlifter does 3 x 10^3 j of work?

Multiply the weight by gravity ( 9.81) and then by the distance:

A) 100 * 9.81 * 2.25 = 2207.25 = 2.2 x 10^3

B) 150 * 9.81 * 1.76 = 2589.84 = 2.6 x 10^3

C) 200 * 9.81 * 1.50 = 2943 =  = 2.9 x 10^3 ( Can round to 3.0 x 10^3

D) = 275 * 9.81 * 1.25 = 3372.18 = 3.4 x 10^3

The answer should be C.

the results is a decrease in air temperature with an increase of altitude.

explanation:

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
