Answer:
ExplanProject Torque was the free North American version of Level-R. It is a multiplayer online racing game (MMORG) with partially chargeable content, or micro-transactions. It features gameplay elements such as tuning and customization. The game is titled as Level R in Europe with a slightly different game interface and menus. Europe, US, Russia, Indonesia, Thailand, China, and Japan versions, are developed by Invictus Games and are subject to Invictus copyrightation:
<span>The statement : According to the law of conservation of energy, the total amount of energy in the universe does not change, but remains constant - is TRUE. The main point which led me to decide is that our universe is the example of a closed system which means there's nothing inside. Hope you will agree with my opinion.

Answer: 210.2N
Explanation:
Assume a bucket of water with a total mass of 68kg is attached to a rope, which in turn is tied around a 0.078m radius cylinder at the top of a well. A crank with a turning radius of 0.250 m is attached to the end of the cylinder.
the minimum force directed perpendicular to the crank handle required to raise the bucket is
(Assume the rope's mass is negligible, that the cylinder turns on friction-less bearings, and that g = 9.8 m/s2
The crank handle provides a torque T=0.25F where F is the force we are looking for.
A free body diagram will show that the tension in the rope times the cylinder radius R is equal to the torque on the cylinder. But the tension in the rope is just the weight of the bucket
W=mg= 68kg
W(0.078)=T=0.25F
F=0.312W=0.312(68kg)=21.216kg= 210.2N
My answer is. Acceleration is the difference between velocities at two times divided by the difference in the times.
Hi lamy
we know ΔU=qΔV
solving for potential difference ΔV
we get ΔV=ΔU/q
ΔV= (Ub-Ua)/q
Ub is potential energy at b
Ua is potential energy at a
q is the charge of the particle
plug in and find out
