A or c I’m pretty sure it’s c though hope it helps:)
Answer:
A meteorologist is a scientist who studies weather Explanation:
A baryon is a particle consisting of three quarks or three antiquarks.
In order to form a neutral baryon (such as the neutron, which has electric charge zero), we must have two quarks with charge
(down, strange or bottom quark), and one quark with charge
(up, charm or top quark), so that the total charge will be zero:
A second possibility is to have a neutral baryon consisting of three antiquarks, of which two of them have charges
(anti-down, anti-strange or anti-bottom), and one of them has charge
(anti-up, anti-charm or anti-top), so that the total charge is still zero:
Let's apply an equation of equilibrium to the situation: The sum of the moments about the left end of the board must equal 0.
We have three moments to add. Positive force values indicate upward direction and negative values indicate downward direction. All distances given below are measured to the right side of the left end of the board:
- The weight of the board, -125N, located at 2m (center of the board due to its uniform density)
- The tension in the right chain, +250N, located at 4m
- The weight of the person, -500N, located at a distance "x"
The sum of the moments must equal 0 and is given by:
ΣFx = 0
F is the magnitude of force, x = distance from the left end of the board
Plug in all of the force and distance values and solve for x:
ΣFx = 250(4) - 125(2) - 500x = 0
500x = 750
x = 1.5m
