Explanation:
In vector geometry, the resultant vector is defined as: “A resultant vector is a combination or, in simpler words, can be defined as the sum of two or more vectors which has its own magnitude and direction.”

The statement the mechanical advantage of the lever is 16 is False.
<h3>Mechanical Advantage</h3>
Mechanical advantage MA = d/D where
- d = distance moved by effort and
- D = distance moved by load
Given that the effort arm is 8 meters long, d = distance moved by effort = 8 m.
Also, given that the resistance arm is 2 meters long, D = distance moved by load = 2 m.
<h3>Calculating the mechanical advantage</h3>
So, substituting the values of the variables into the equation, we have
MA = d/D
MA = 8 m/2 m
MA = 4
Since MA = 4, so, the stament is False.
So, the statement the mechanical advantage of the lever is 16 is False.

a Without the atmosphere, average temperature on Earth would be freezing! Below zero to be exact!
b The atmosphere protects us and animals from dangerous radiation from the Sun. Ultraviolet radiation is basically invisible rays of energy created by the sun.
cAlso, the atmosphere provides oxygen for humans and animals to breathe and C02 (Carbon dioxide) for plants.
4 warmth
5 yes it is The water on our Earth today is the same water that’s been here for nearly 5 billion years. Only a tiny bit of it has escaped out into space. As far as we know, new water hasn’t formed either.
That means there’s a very high chance the water in your glass is what thirsty dinosaurs were gulping about 65 million years ago.
Answer:
1, 2, 4, 5 are correct
Explanation:
1) This is true because In a neutral atom, the number of positive charges (protons) is equal to the number of negative charges (electrons).
2) This is true because the mass of the atom which is made up of the protons and neutrons, is located in the tiny nucleus.
3) This is not true because the positively charged particles in the nucleus are called protons.
4) This is true because electrons move around the nucleus in diffuse areas known as orbitals.
5) This is true because opposite charges attract each other. And electron is a negative charge.
6) This is not true because the radius of the electron cloud is normally 10,000 times larger than the radius of the nucleus.
