Why is the objective lens of a refracting telescope so much larger than the eyepiece lens?

Because the eyepiece lens just needs to refract off of the objective lens and so the objective lens needs to be bigger so you can see something from a distance I hope this helps

Antimony is like a nonmetal in that it is a brittle, crystalline solid, has poor electrical and heat conductivity, and has a low
Reil [10]

Answer is B. It is a metalloid.

Metalloid is a chemical element that has characteristics of both metals and non- metals.

Antimony is brittle,is a poor conductor of heat and electricity,has a low boiling point and is a crystalline solid. These are some of the characteristics which a non-mechanical has.

It can also be classified as a metal due to its ability to form alloys easily and due to it's shiny silver appearance.Antimony alloys are used in batteries.

Hey there!
Alright, it looks like you've got the second question on the top right, but I can't figure out the answer you've got for the first.
Using Newton's Second Law Of Motion, we have:
F = ma
We plug in our values:
F = 5(1)
That would give us 5 Newtons of force.
For the last one:
Even if two balls are given the same acceleration, the determining factor is <em>weight.</em> If a ball is lighter, it needs less acceleration to go faster. If it's larger, it needs more to make it go at that same speed. That's why that 5 newtons makes sense because it's 5 kilograms as opposed to 0.6 kilograms. It's heavier, and needs more force.
Hope this helped!

NeTakaya

Magnitude of acceleration

Explanation:

We know that acceleration can increase depending in the force applied on an object, any object with a greater mass will apply a greater force. F = M(a).
