Answer:
1. A long crack in the oceanic crust forms at a mid ocean ridge
Explanation:
(a) The speed of light in the unknown substance is determined 1.82 x 10⁸ m/s.
(b) The light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.
<h3>What is the speed of light?</h3>
The speed of light passing from air into the substance is calculated as follows;
refractive index = speed of light in air / speed of light in the substance
speed of light in the substance = speed of light in air/refractive index
speed of light in the substance = (3 x 10⁸) / (1.65)
speed of light in the substance = 1.82 x 10⁸ m/s
Thus, the light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.

What’s the full question? Imma say the depth of the wells are different and therefore some have oxygen all the way to the bottom!
Energy is transferred from the Al (solid) to water and the temperature of the water increases while the temperature of the Al (solid) decreases.
<h3>Heat energy</h3>
Heat energy is a form of energy transferred from one body to another due to a temperature difference between the bodies.
Heat energy is also known as thermal energy.
In heat transfer, heat is transferred from a body at higher temperature to a body at lower temperature.
In the heat transfer between the heated aluminium and the water, the solid aluminium is at a higher temperature than the water, hence, heat energy is transferred from the aluminium to water.
Therefore heat energy is transferred from the Al (solid) to water and the temperature of the water increases while the temperature of the Al (solid) decreases.

is the nuclear equation for the beta decay Ni-60.
<h3>What is beta decay?</h3>
Beta-decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.
The nuclear equation for the beta decay Ni-60
In beta minus (β−) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino; while in beta plus (β+) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β+ decay is also known as positron emission.
Hence, is the nuclear equation for the beta decay Ni-60.
