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 equilibrium line<span> separates the ablation zone and the accumulation zone; it is the altitude where the amount of new snow gained by accumulation is equal to the amount of ice lost through ablation. The upper part of a </span>glacier<span>, where accumulation exceeds ablation, is called the accumulation zone.</span>
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 = 
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 = 
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 = 
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
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.
