Assume that you have a meter stick balanced on a pivot, and pile of additional masses that you can hang on the meter stick.

Physics

Viefleur [7K]3 years ago
5 0

Answer:

You will not need any mass to determine the mass of the stick.

Explanation:

The mass of an object, like the stick, can only be determined according to Newton's second law, which states that the mass of an object is equal to the force of that object, divided by the mass of the object. It is obvious that we do not know what is the force and acceleration value of the stick shown in the question above, however, it is impossible to know what is the mass of it, adding external masses to the stick.

Sergio [31]

Answer:

* Larger mirrors collect more light and therefore fainter and more distant objects can have enough intensity to be detected

* arger mirrors decreases the angle of dispersion giving a better resolution of the bodies

Explanation:

Refracting telescopes get bigger every day for two main reasons.

* Larger mirrors collect more light and therefore fainter and more distant objects can have enough intensity to be detected

* the diffraction process for circular apertures is given by

               θ = 1.22 λ / D

where d is the diameter of the mirror, therefore having larger mirrors decreases the angle of dispersion giving a better resolution of the bodies
