Answer:
Explanation:
The radial velocity method involves watching the spectral lines of a star as a planet orbits the star. Because of the planets gravitational pull on the star, the star will wobble. This causes Doppler shifts in the spectral lines, allowing astronomers to infer the presence of the planets.
Answer:
The electron has a negative charge and is found outside of the nucleus.
Explanation:
1.) Neutrons have no charge, not a negative charge.
2.) Neutrons are found inside the nucleus, not outside.
3.) Protons have a positive charge.
Let us assume that the density of seawater is similar to
ordinary water that is:
density ρ = 1000 kg / m^3
Then we can calculate the hydraulic pressure using the
formula:
P = ρ g h
P = (1000 kg / m^3) * 9.81 m/s^2 * 9,500 m
<span>P = 93,195,000 Pascal</span>
Answer with Explanation:
We are given that
a.Length of segment,l=20 m
Magnetic force ,F=
Substitute the values
Hence, the magnetic force exert by each segment on the other=0.0119 N
b.We know that when current carrying in the wires are in same direction then the force will attract to each other.
Hence, the force will be attractive.
If your choices are the following:
<span>
A faultblock mountain
A folded mountain
A hotspot volcano
A volcanic arc
</span>
Then the answer is A folded mountain. It is formed when an earthquake happened and this was the result of the movement of the plates.
