A pulley system conisisting of three pulleys is used to lift a pallet
of
bricks Weighing 600N
through a height of 40m. The
force required to lift the pallet
at a
steady speed is 210N and the rope is pulled through a distance of 120m

(a) Neglecting
the mass
of the pulleys and rope, calculate the useful work
done in lifting the pallet. ​

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
