On mars people would way less.
An example of this is that if I weighed 700 pounds (I don't by the way) I would then weigh 500 pounds or less.
Answer:
The separation between the charges was decreased by a factor of 0.2
Explanation:
The Coulomb's force between two charges is given by;
r₂ = 0.2r₁
Therefore, the separation between the charges was decreased by a factor of 0.2.
The time taken by the stone to hit the ground would be 5.12 seconds.
<h3>What are the three equations of motion?</h3>
There are three equations of motion given by Newton
The first equation is given as follows
v = u + at
the second equation is given as follows
S = ut + 1/2×a×t²
the third equation is given as follows
v² - u² = 2×a×s
Keep in mind that these calculations only apply to uniform acceleration.
As given in the problem, a stone is dropped from the helicopter which is ascending at the speed of 19.6 m/s
height(S) = 156.8 meters
initial velocity(u) = -19.6 m/s
acceleration(a) = 9.81 m/s²
By using the second equation of motion given by newton
S = ut + 1/2at²
S = 156.8m ,u= -19.6 m/s , a= 9.81 m/s² and t =? seconds
156.8= -19.6t + 9.81t²
t = 5.12 seconds
Thus, the time taken by the stone to hit the ground would be 5.12 seconds.

Human hox genes are in four clusters: HOXA, HOXB, HOXC, and HOXD for a total of 39 genes. besides conserving the clustering of genes, evolution has also conserved the order of genes within them.
What is a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes helps to make molecules called proteins. However, many genes do not synthesis for proteins. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different among the people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Explanation:
It is given that,
Height of the building, h = 44 m
Initial horizontal velocity, 
Initial vertical velocity, 
It can be assumed to find the maximum height of the projectile and time taken to reach the maximum height.
The formula for the maximum height is given by :
g is the acceleration due to gravity
The total maximum height, h' = h + H
The formula for the time of flight is given by :
Hence, this is the required solution.
