Solution: Expansion
Explanation:
When we put a glass bottle in the freezer, the volume of water is supposed to expand causing high surface tension leading to the glass to crack. As the volume of water increases, there is less space for the water to fit in.
Answer:
xxxxx
Explanation:
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a Volume (the same volume as 1 milliliter).
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
