Answer:
e. none of these
Explanation:
An object in FREE-FALL on the MOON would experience only acceleration
Answer:
The fusion reaction in the Sun is as follows
₁¹H+ ₁¹H ---> ₁²H + ₊₁°e⁺+ ν
₁²H+ ₁¹H ---> ₂³He + γ
₂³He + ₂³He ---> ₂⁴He + ₁¹H+ ₁¹H
So comparing these equations with options given.
We will get option A is the correct answer that
₁¹H+ ₁¹H ---> ₁²H + ₊₁°e⁺+ ν
Slope is actually speed but the best answer from the choices would be velocity.
The velocity of the rollercoaster going down the hill is equal to 5.270 m/s.
<u>Given the following data:</u>
- Mass of rollercoaster = 1,800 kilograms.
- Kinetic energy =25,000 Joules.
To calculate the velocity of the rollercoaster going down the hill:
<h3>
Formula for kinetic energy.</h3>
Mathematically, kinetic energy is calculated by using the formula;

<u>Where:</u>
- K.E is the kinetic energy.
- M is the mass of an object.
- V is the velocity of an object.
Making V the subject of formula, we have:

Substituting the given parameters into the formula, we have;

Velocity, V = 5.270 m/s

Answer:
b .at the outer edge of the Galactic Disk
Explanation:
The sun is located on the outeredge of the galaxy. So it has an orbit within our Milky Way galaxy that is also located arround the <u>outer edge of the galactic disk</u>, and goes around in about 30 million years.
In reallity, allong its trayectory, the sun goes above and below the gallactic disk, but it stays in the outer edge of the galaxy, <u>far away from the galactic bulge and the galactic center</u>, but closer to it than the galactic halo.
