Electric Automobile Lifts
Physics/Chemistry questions?
1. If you exert a force of 11 N to lift a box a
distance of 1.56 m, how much work do you
do?
Answer in units of J.
2. In a gaseous mixture of massive molecules
and light molecules with the same average
KE, which have the greater speed?
a. Cannot be determined
b. They have the same speed.
c. the light molecules
d. the massive molecules
3.An example of stored chemical energy is
a. gasoline in an automobile.
b. an electric motor.
c. light.
D. the sun’s energy.
If I could get some help on these questions than that would be a real help. 
1. Formula for work done:
W=F*d (1 J= 1 N.m)
2.Definition of KE: The energy of motion.
So you've got to think through this question:
what is the energy of motion relative to the weights of the molecules??
3. self explanatory!

The Gasoline Automobile $24.66 Henry Ford introduced his Model T in 1908, and changed the face of America. The arrival of the Tin Lizzie on city streets also signaled the beginning of the end for a debate that had raged since the beginning of the motor car era.

Originally published in 1915 as an engineering text, The Gasoline Automobile is a classic book that provides rare insights into the early days of the automobile revolution. Within its pages you will find descriptive text supported by numerous rare photos and illustrations. Chapters include: general construction, engines, power plant groups and transmission systems, fuels and carburetor systems, lubrication and cooling, batteries and ignition, magnetos, starting and lighting systems, troubles and remedies, and operation and care. This softcover reprint of the first edition has been slightly reformatted for readability, but care has been taken to preserve the integrity of the text.

Electric Hatch Lifts Hatch Lift 12V Extended 65 $504.94 Electric Hatch Lifts Hatch Lift 12V Extended 65" 750 Pounds of 12V Electrical Power LiftThe function of the Lenco hatch lift system is simple. Since the hatch lift is based around a ballscrew, it is able to push or pull a heavy load and remain at a constant position. To raise a load, extend the hatch lift by pressing on the upper part of the switch. To lower a load, retract the hatch lift by pressing the lower part of the switch.In case of power failure, Lenco hatch lifts are supplied with two clevis pins at the mounting brackets. To pull this pin out while the hatch is closed you must rig it to a point outside of the hatch.The actuator is most powerful when it is installed vertically at 90°Lifting capabilities decrease the closer the upper or lower mount is located to the hingeThe further it is from a vertical position the less lifting capabilityWhen retracted, do not position hatch lift at an angle less than 30°Dual actuator systems are recommended for hatches over 500 lbs.For installation, it is important that the hatch lift is able to disengage itself at the fully retracted position. Failure to make accurate measure could cause damage to hatch lift or the hatch itselfLenco hatch lifts are fully submersible and will not driftLenco hatch lifts are offered in both 12 and 24 volts |
