The balls are not perfectly elastic, but the main reason is probably air.
Explanation:
When 2 adjacent balls have any distance between them, there is air in the space. When the moving neighbor comes at a stationary ball the moving ball has to push the air out of the way.
I hope this helps

If a large marshmallow has a volume of 2.00 in3 and density of 0.242 g/cm3, how much would it weigh in grams? 1 in3=16.39 cm3.
siniylev [52]

First convert the inches cubed to centimeters cubed. Looking at the rate, we can write 2 inches cubed = 2 * 16.39 cm cubed = 32.78 cm cubed.

The equation for density is D = M/V, where D is the density, M is the mass, and V is the volume. Substitute the values into the equation:

0.242 = M/32.78

Multiply by 32.78 on both sides.

The mass is about 7.93 grams.

You analyze a cell in your microscope likely effect of this cellular defect?
bezimeni [28]

Answer:

This question has no options but it can be answered based on the understanding of the function of ribosomes.

The effect is the deficiency of proteins in the cell.

Explanation:

Ribosomes are one of the most important cellular organelles found in living organisms. Infact, they are so important that they are found in both the prokaryotic and eukaryotic cell. Ribosome functions in PROTEIN SYNTHESIS as they are the site where the mRNA encoding protein building blocks (amino acids) undergo their translational process.

According to this question, an analyzed cell is found to be missing most of its ribosomes. This means that the function performed by the missing organelle, which is SYNTHESIS OF PROTEINS, will be lacking. Hence, that particular cell will be PROTEIN-DEFICIENT.

Balance each of the following redox reactions occurring in basic solution.MnO−4(aq)+Br−(aq)→MnO2(s)+BrO−3(aq)Express your answer
Ahat [919]

Answer : The balanced chemical equation is,

2MnO_4^-(aq)+Br^-(aq)+H_2O(l)\rightarrow 2MnO_2(s)+BrO_3^-(aq)+2OH^-(aq)

Explanation :

Rules for the balanced chemical equation in basic solution are :

  • First we have to write into the two half-reactions.
  • Now balance the main atoms in the reaction.
  • Now balance the hydrogen and oxygen atoms on both the sides of the reaction.
  • If the oxygen atoms are not balanced on both the sides then adding water molecules at that side where the more number of oxygen are present.
  • If the hydrogen atoms are not balanced on both the sides then adding hydroxide ion (OH^-) at that side where the less number of hydrogen are present.
  • Now balance the charge.

The half reactions in the basic solution are :

Reduction : MnO_4^-(aq)+2H_2O(l)+3e^-\rightarrow MnO_2(s)+4OH^-(aq) ......(1)

Oxidation : Br^-(aq)+6OH^-(aq)\rightarrow BrO_3^-(aq)+3H_2O(l)+6e^-  .......(2)

Now multiply the equation (1) by 2 and then added both equation, we get the balanced redox reaction.

The balanced chemical equation in a basic solution will be,

2MnO_4^-(aq)+Br^-(aq)+H_2O(l)\rightarrow 2MnO_2(s)+BrO_3^-(aq)+2OH^-(aq)
