A ball thrown by Ginger is moving upward through the air. Diagram A shows a box with a downward arrow. Diagram B shows a box wit
vichka [17]

As the ball is moving in air as well as we have to neglect the friction force on it

So we can say that ball is having only one force on it that is gravitational force

So the force on the ball must have to be represented by gravitational force and that must be vertically downwards

So the correct FBD will contain only one force and that force must be vertically downwards

So here correct answer must be

<em>Diagram A shows a box with a downward arrow. </em>

The distance that a person can see to the horizon on a clear day from a point above the surface of Earth varies directly as the
lara [203]

Answer:

900 m ( 0.9 km)

Explanation:

from the question we have the following

first person's height  (h) = 100 m above the earths surface

distance to the horizon that can be seen (s)  = 15 km = 15,000 m

second person's height  (h1) = 36 m

distance to the horizon that can be seen (s1) = ?

take note that the distance (s) a person can see = square root of the person's height

s = \sqrt{h} x K

where k is a constant

from the height and the distance the first person can see we can get the value of K

15000 = \sqrt{ 100} x K

15000 = 10 x K

K = 150

now putting the value of K and the height of the second person into the equation we can get the distance into the horizon the person can see

s =  \sqrt{36} x 150

s = 900 m

therefore the second person who is 36 m above the surface can see 900 m ( 0.9 km) into the horizon

If a nucleus was as big as a nonpareil, an atom would be ____
Mamont248 [21]

Answer:

small marble  

Explanation:

A nonpareil are confectionery tiny ball items that are made up of starch and sugar. It is very small of the size of sugar crystal or sand grains. They were the miniature version of the comfits. They are generally opaque white but bow available in all colors.

In the context, if the nucleus is compared to the size of a nonpareil then its atom would be of the size of small size marble. An atom is bigger in size than that of nucleus as the nucleus is located inside the atoms.
