An atom has eight protons.
Since each proton has a charge of +1, the whole atom
so far has a charge of +8 .
If we want an overall charge of only +2, we need to cancel
or neutralize 6 of those positive charges somehow.
We have two choices:
==> rip off 6 protons and throw them away
Well, the protons are in the nucleus. It's almost impossible to
rip particles out of a nucleus, and if you manage to do it, you
end up with a completely different substance. So the first choice
doesn't seem like the way to go. Let's look at the second one.
==> glue something onto the atom that has 6 negative charges
NOW we're getting somewhere !
ELECTRONS have negative charges ... 1 apiece.
Electrons are everywhere, they're easy to get, and easy to
work with. We could go on Amazon and order 6 electrons,
we could have them by tomorrow, and GET THIS: Opposite
charges attract each other anyway, so if we bring the electrons
anywhere near the 8 protons, they'll snap in and get glued on
automatically. THIS is the way to change our atom to +2 ...
with some electrons.
Answer:
The strength of gravity on Pluto is 0.6 m/s²
Explanation:
The given mass of the shoe = 0.5 kg
The weight of the shoe (on Pluto), W = 0.3 N
Therefore, given that weight, W = Mass × The acceleration due to gravity, We have;
The strength of gravity = The force gravity applies to each unit of mass = The acceleration due to gravity (in m/s²)
The weight of the shoe, W = The mass of the shoe × The strength of gravity on Pluto
Substituting the known values, gives;
0.3 = 0.5 × The strength of gravity on Pluto
∴ The strength of gravity on Pluto = 0.6 m/s².
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical
Answer:
Explanation:
We are given that
Distance between plates=d=2.2 cm=
Using 
We have to find the magnitude of E in the region between the plates.
We know that the electric field for parallel plates
Where 
Substitute the values
Hence, the magnitude of E in the region between the plates=
It is b i had that qustion
