Answer:
Slope in Mathematics means the inclination of a line
To solve this problem it is necessary to apply the concepts related to the centripetal Force, the Force of the weight produced by the gravity of the star and the definition of the velocity as a function of time (period)
In other words, for balance to exist, the force acting on the body (weight) must be equal to the centripetal force that attracts it in motion. That is to say
The value of the given period is 110min or 6600s.
At the same time we know that the speed of a body depending on its period (simple harmonic movement) is subject to
Finally, replacing this value in the event of gravity we have to
A mixture IS NOT a chemical combining of substances. If substances
combine chemically, then they form a compound, not a mixture.
Mass is the scalar quantity. (A)
Velocity, force, and acceleration are vectors.
