Answer:
<u>Box 1</u>
Explanation:
Formula we are using :
<u>Force = mass × acceleration</u>
or
<u>mass = Force / acceleration</u> (since mass needs to be found)
=============================================================
Box 1 :
⇒ mass = 5 N / 5 m/s²
⇒ mass = 1 kg
=========================================================
Box 2 :
⇒ mass = 5 N / 0.75 m/s²
⇒ mass = 5 × 4/3 = 20/3 kg
⇒ mass = 6.67 kg
===========================================================
Box 3 :
⇒ mass = 5 N / 4.3 m/s²
⇒ mass = 50/43 kg
⇒ mass = 1.16 kg
===========================================================
On comparing Box 1, Box 2, and Box 3, we understand that <u>Box 1</u> has the smallest mass
It is reflection off of something colored
Answer:
1. Astronomers noticed that the orbits of Neptune and Uranus were being affected by the gravity of an unknown object in the Solar System. Clyde Tombaugh carefully studied images of the night sky, and after a lot of hard work he finally discovered Pluto.
2. Well, Pluto was most likely difficult to find, because of its small size and great distance from Earth.

A) 17.9 cm
We have:
is the focal length of the mirror (for concave mirror, the focal length is positive)
is the distance between the object and the mirror
is the distance between the image and the mirror
We can then use the mirror equation to find q:
B) -5.0 cm
The height of the image can be determined by using the magnification equation:
where
is the heigth of the image
is the height of the object
Substituting and re-arranging the formula, we find
And the negative sign means the image is inverted.
