The density of an object is the ratio of its mass over the volume. This translates to the amount of substance present in a certain space and can mathematically be expressed as,
density = mass / volume
In this item, we are given that the object of mass 1.41 kg is able to displace 0.314 L of liquid. The volume of water displaced is also the volume of the object. Hence,
density = 1.41 kg / 0.314 L = 4.49 kg/L
Then, we convert the calculated volume of g/mL.
density = (4.49 kg/L)(1 L / 1000 mL)(1000 g/1 kg)
<em> density = 4.49 g/mL</em>
Answer:
this is it
Explanation:
For every 9 turns of the driver the follower will make 4 complete rotations!
Since they are both positively charged, then the force would in fact be repulsion, because they are both the same. If you were to have one positively charged, and one negatively charged, then they would go towards eachother.

1. At the end of asexual reproduction the resulting cell is an exact genetic copy of the original cell.
2. During inter phase the cell copies its DNA, and grows to an appropriate size where it is safe for the cell to split.
3. After meiosis, the resulting daughter cells are 4 genetically different haploid daughter cells.
4. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. The two haploid gamete bring different traits together, they also shares some DNA. This makes each daughter cell unique.
Answer:
So speed of electron will be 
Explanation:
We have given potential difference V = 9.9 KV
Charge on electron 
So energy of electron 
This energy of electron will be equal to kinetic energy of electron
So 
So speed of electron will be
