The initial (starting) volume of water in the graduated cylinder can easily be determined by observing the level of water on the cylinder through the water's meniscus.
The initial volume of water in the cylinder during a laboratory experiment is determined by observing the level of water on the cylinder.
A measuring cylinder can be graduated by 1 mL and can measure up 100 mL, 150 mL, 200 mL or more.
To determine the accurate measurement of initial volume of water in the graduated cylinder, this measurement should be taken as follows;
- <em>Read off the position of the water meniscus at eye level</em>
- <em>Avoid shaking the water before taking the measurement</em>
Thus, the initial (starting) volume of water in the graduated cylinder can easily be determined by observing the level of water on the cylinder through the water's meniscus.

Answer:
The correct answer is option B)
Explanation:
Considering the given question as -
The space shuttle is located exactly half way between the earth and the moon. Which statement is true regarding the gravitational pull on the shuttle? A) The moon pulls more on the shuttle. B) The earth pulls more on the shuttle. C) Both are equal due to equal distances. D) Both are equal due to the mass of the shuttle.
We know that gravitational pull (F) between any two bodies of mass and is given by -
F = where 'r' is the distance between the two bodies.
Let ,
: Mass of the earth
: Mass of the moon
m : Mass of the satellite
: Distance of satellite from earth
: Distance of satellite from moon
Given that =
Let ==r
Force on satellite by the earth is -
=
Force on satellite by the moon is -
=
∵ Mass of earth () > Mass of moon ()
∴ >
∴ The gravitational pull of earth on satellite is more than that of the moon.
