The incline is frictionless, this means we can use the conservation of energy: the initial kinetic energy of the block
is converted into gravitational potential energy
where h is the height reached by the block as it stops. By equalizing the two formulas, we get
However, this is the maximum height reached by the block. The distance along the surface of the plane is given by:
MgCl2
Mg = magnesium
Cl = chlorine
Magnesium + chlorine = magnesium chloride.
This is because compounds are always written with the METAL FIRST and the NON METAL SECOND. the non metal ends in - ide when it reacts with a metal.
So ur answer would be magnesium chloride. :)
The charge on the conductor is +24 μC, since the charge is positive, same amount of charge but it will be negative.
That is - 24 μC.
To know the number of electrons, we know that the charge of an electron =
-1.6 * 10^-19 C.
= - 24 μC / (-1.6 * 10^-19 C)
= (-24 * 10^-6) / (-1.6 * 10^-19 C) Use your calculator
= 15 * 10^13
= 1.5 * 10 ^14 Electrons.
