Answer:
Explanation:
As we know that system of two gliders are moving on frictionless track
so momentum conservation is applied on it
So we will have
so we will have
now we know that collision is elastic so we have
so by solving above equations we have
Answer:
Explanation:
As with all atoms known, electrons moves in discrete energy levels round a well defined orbit.
Protons are restricted to the nucleus of an atom. They occupy this small and massive position along with the neutrons.
Metals, have a large dense cloud of electrons.
- Every atom is made up of three fundamental particles.
- Protons, neutrons and electrons are these particles.
- Protons are positively charged and they occupy the tiny nucleus. Neutrons are found in the nucleus with them. They do not carry any charge.
- It is correct to infer their position as being fixed.
- Electrons occupies the bulk of the volume of the atom.
- They orbit round the tiny nucleus.
Therefore, it is safe to conclude that in metal conductors, electrons move but protons do not just like in every other atom.
Hydrogen .When acids touches all metal hydrogen gas is emitted .Strong acids is one that can produce a high concentration of hydrogen ions.Hope this helped!
Answer with Explanation:
We are given that
Force=F=112 N
Distance,
Time, t=3.33 minutes
We have to find the work done by Johnson on the bag and the power generated by Johnson.
Work done, W=
Using the formula
Work done, W=
Power, P=
Using 1 minute=60 s
Hence, the power generated by Johnson=33.3 watt
