Answer:
Spectra type M
Explanation:
mass spectrum is simply an intensity vs. m/z (mass-to-charge ratio) plot representing a chemical analysis. Hence, the mass spectrum of a sample is a pattern representing the distribution of ions by mass (more correctly: mass-to-charge ratio) in a sample. It is usually acquired using an instrument called a mass spectrometer. Not all the mass spectra of a given substance are same.
The magnitudes of forces at F₁ and F₂ are :
F₁ = 3924 N
F₂ = 4120.2 N
We know that force is the amount of strength required to move a body. The magnitude of force is the sum of all the strengths applied on the body which is exerted by each force together on a particular body.
Given,
Length of plank = 2 m
Force on one end = F₁
Force on the other end = F₂
F₂ is applied to a point which is 0.5 m from the other end
Mass of plank = 20 kg.
Now let us calculate the magnitudes of the forces applied:-
1) Balance of angular momentum around the end where F₁ is applied.
F₂ × 0.5m - F₁ × 0 = mass × g × 1m
⇒ F₂ × 0.5 m= 20 kg × 9.81 m/s² × 1 m = 1,962 N×m
F₂ = 196.2 Nm / 0.5m = 3,924 N
2) Balance of forces
F₁ - F₂ = mg
F₁ = F₂ + mg = 3,924N + 20kg (9.81 m/s²) = 4,120.2 N
Therefore the magnitude of force F₁ is 3924 N and of force F₂ is 4120.2 N.

I believe the answer is D. Thunderstorm
Unstable air indicates that <span>the lowest layers of an </span>air<span> mass is low in temperature. Thunderstorms is more likely to happen if there is unstable air mass because it provide a situation where there is more energy for the Thunderstorms to feed off of.</span>
Answer:
The force exerted by the chain is 117N
Explanation:
We have to draw a free body diagram to visualize this problem better.
according to Newton's second law:
but the roller coaster is having a constant speed so:
So:
If molecule gains heat energy covenrts liquid to gas
