If there is no friction, the roller coaster would keep moving forever but a constant velocity. The only way it would accelerate is if there was a force continually pushing on it.
4) They have non-moving magnetic fields.
Answer:
Explanation:
Stocks give you partial ownership in a corporation, while bonds are a loan from you to a company or government. The biggest difference between them is how they generate profit: stocks must appreciate in value and be sold later on the stock market, while most bonds pay fixed interest over time.
For this we need to use sinus law because there is no right angle in the observed triangle to solve it in some easier way.

where a is height of the water tower, b is length from point of view till bottom of the tower,

is the angle from point of view and

is angle opposite from b.
We use this law to calculate beta angle.



Now we observe different angle. Bottom of the hill-top of the tower-point of view. We calculate angle at point of view (notice how it is different than previous one).
180-90-47.924 = 42.076
At last, the hill inclination is:
42.076 - 8 = 34.076 = 34.1
Answer:
1. Protons
Explanation:
In a neutral atom, the number of electrons equals the number of protons within the atom.
Protons are the positively charged particles
Electrons are the negatively charged particles
Neutrons do not carry any charges.
Therefore, the number of protons and electrons in a neutral atom is the same and this leaves a net zero charge on the atom.
Ions usually have varied number of protons and electrons.
