Answer:
-200°C
Explanation:
This is because at -200°C the temperature is below -196°C and above -210°C .Thus Nitrogen can be in liquid state.
Ocean levels are not greatly affected because when water is deposited or received from the ocean, at the same time water is being evaporated from the ocean to condense in the clouds and them form into precipitation.
An electron is emitted from a nucleus- State the effect this has on the charge of the nucleus
Answer:
an electron orbiting around the nucleus combines with a nuclear proton to produce a neutron, which remains in the nucleus, and a neutrino, which is emitted. As in positron emission, the nuclear positive charge and hence the atomic number decreases by one unit, and the mass number remains the same.

Answer:
3.6m/s
Explanation:
The following data were obtained from the question:
Mass (m) = 0.5Kg
Spring constant (K) = 330N/m
Energy = 3.24J
Velocity (v) =..?
The velocity of the mass can be obtained as follow:
E = ½mv²
3.24 = ½ × 0.5 × v²
3.24 = 0.25 × v²
Divide both side by 0.25
v² = 3.24/0.25
Take the square root of both side
v = √(3.24/0.25)
v = 3.6m/s
Therefore, the speed of the mass is 3.6m/s
