The SI unit of force is the<em> Newton</em> .
1 Newton is the force that accelerates 1 kilogram of mass at the rate of 1 meter per second-squared.
1 pound of force is roughly 4.45 Newtons of force.
So 1 Newton of force is roughly 3.6 ounces of force.
1 kilogram of mass weighs about 9.81 Newtons on Earth. That's the same as 2.205 pounds.
Explanation:
1.) Work = Force*Distance
2.) The direction of motion lies in the same direction as the tension in the cable. So the work done by tension would be positive.
3.) The direction of the weight (due to gravity) would act opposite to the direction of motion of the elevator, so work done by gravity becomes negative.

Venus. The atmosphere of Venus, in fact, is full of carbon dioxides, the main contributor to the dramatic greenhouse effect on the planet, which causes the surface temperature of Venus to reach 460 degrees Celsius. Without this effect, the surface temperature of Venus will be more similar to Earth's one (still a bit higher, given the smaller distance from the Sun).
