Two similar objects are moved by two bulldozers. If the work accomplished by bulldozer #2 was three times greater than bulldozer #1 then: Both bulldozers did equal work because the objects are similar. Bulldozer #2 had to move 3 times greater distance. Bulldozer # 1 had to move 3 times greater distance. Bulldozer #2 had to require 3 times greater power.

Which two objects have the greatest gravitational force acting between them

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force
