Answer:
R = 4.24 x 10⁻⁴ m
Explanation:
given,
mass of the person = 60.3-kg
mass of the bullet = 10 gram = 0.01 Kg
velocity of bullet = 389 m/s
angle made with the horizontal = 45°
using conservation of momentum.
M v + m u = ( M + m ) V
60.3 x 0 + 0.01 x 389 = (60.3 + 0.01) V
![V = \dfrac{3.89}{60.31}](https://tex.z-dn.net/?f=V%20%3D%20%5Cdfrac%7B3.89%7D%7B60.31%7D)
![V = \dfrac{3.89}{60.31}](https://tex.z-dn.net/?f=V%20%3D%20%5Cdfrac%7B3.89%7D%7B60.31%7D)
V = 0.0645 m/s
for calculation of range
![R = \dfrac{V^2sin 2 \theta}{g}](https://tex.z-dn.net/?f=R%20%3D%20%5Cdfrac%7BV%5E2sin%202%20%5Ctheta%7D%7Bg%7D)
![R = \dfrac{0.0645^2sin 2 (45^0)}{9.8}](https://tex.z-dn.net/?f=R%20%3D%20%5Cdfrac%7B0.0645%5E2sin%202%20%2845%5E0%29%7D%7B9.8%7D)
R = 4.24 x 10⁻⁴ m
the distance actor fall is R = 4.24 x 10⁻⁴ m

Answer:
Diamagnetic
Explanation:
Hunds rule states that electrons occupy each orbital singly first before pairing takes place in degenerate orbitals. This implies that the most stable arrangement of electrons in an orbital is one in which there is the greatest number of parallel spins(unpaired electrons).
For vanadium V ion, there are 18 electrons which will be arranged as follows;
1s2 2s2 2p6 3s2 3p6.
All the electrons present are spin paired hence the ion is expected to be diamagnetic.
Answer:
Explanation:
The properties of magnets are used to make electricity. Moving magnetic fields pull and push electrons. ... Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current.
