  • T1=40°C=313K
  • T_2=-10°C=263K

Applying Charles law

\\ \sf\Rrightarrow \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

\\ \sf\Rrightarrow \dfrac{100}{313}=\dfrac{V_2}{263}

\\ \sf\Rrightarrow V_2=\dfrac{26300}{313}

\\ \sf\Rrightarrow V_2=84.02ml

A golf ball is hit with a golf club. While the ball flies through the air, which forces act on the ball? Neglect air resistance.
34kurt

To solve this problem it is necessary to apply the equation related to the Gravitational Force, the equation describes that

F = \frac{GMm}{r^2}

Where,

G = Gravitational Universal Constant

M = Mass of Earth (or Bigger star)

m = Mass of Object  (or smallest star)

r = Radius

From the statement we know that once the impact is made, the golf ball is subjected to the forces that are exerted in nature. Since the air resistance, which would represent the drag force, is ignored. Only the forces related to gravity remain.

The gravitational force carries 'pushes' or 'attracts' the body towards the earth, while the speed decreases as it reaches its maximum height.

When the ball has reached its maximum height only the force of gravity begins to act on it, generating the attraction to the earth in parabolic motion.

Therefore the correct answer is B.

The mass of the water in the system is one parameter that can be taken into consideration that is kept constant.

Describe a constant.

A constant in science is a kind of unaltered variable that stays constant together with the experimental process.

It is important to take into account a system's constants, which cannot be altered by experiments or observations.

In conclusion, the mass of the water can be taken into consideration as a continuous system parameter.
