Ali was playing with his new U-shaped magnets which he attached with two trolleys and moved both of the trolleys in the same dir
jolli1 [7]

Answer:

The "trolleys" did not collide with each other because <em>their poles repelled. </em>

Explanation:

Magnets have poles located at their ends and these are the "north pole" and the "south pole."

If the north pole of one magnet will be faced to the south pole of another magnet, <em>they will attract each other</em> or <u>pull towards each other.</u> The opposite will happen when the south pole of one magnet will be faced with the same pole from another magnet. <em>They will repel each other</em> or<u> pull away from each other.</u>

Since the magnets attached to the trolleys were U-shaped, this means that the north and south poles are located at the<u> end of the magnets, which face the same direction. </u>So, once the magnets of the two trolleys move towards each other, their poles will repel because same poles will face each other.

So, this explains the answer.

What is Hydroelectric energy used for? Use in your own words.
evablogger [386]
Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia. Over two thousand years ago, people in Greece used flowing water to turn the wheel of their mill to ground wheat into flour.

What it means to say that energy is conserved as a ball fall towards ground
stiv31 [10]
Mechanical energy = Potential Energy + Kinetic Energy

if there is no friction, M.E. is conserved
as a ball falls, it is losing height. (P.E.=mgh , therefore P.E. will decrease)

the potential energy is transformed into kinetic energy which equals 1/2MV^2.

the increase in K.E. equals the decrease in P.E.

and the sum of both equals M.E.

thus mechanical energy is conserved.

hope this helps you.

What is the pressure exerted by 0.801 mol of co2 in a 12 l container?
Svetlanka [38]
We assume that the gas is an ideal gas so we can use the relation PV=nRT. Assuming that the temperature of the system is at ambient temperature, T = 298 K. We can calculate as follows:

PV = nRT
P = nRT / V
P = (0.801 mol ) (0.08205 L-atm / mol-K) (298.15 K) / 12 L
P = 1.633 atm
