Answer:
Due to the chemical versatility of carbon atoms
Explanation:
Carbon is a very important element and it is commonly found in many varieties of chemical compounds. They are also found to be present in space in various amount. It is often considered to be versatile because they are capable of forming single, double, as well as triple bonds. This enables them to make single and branched chains. They also form ring chains when combined with other atoms of carbon.
It is because of this versatility of carbon atoms, there forms complex variety of organic molecules.
Answer:
Approximately
(assuming that the acceleration due to gravity is
.)
Explanation:
Let
denote the first piston's contact area with the fluid. Let
denote the second piston's contact area with the fluid.
Similarly, let
and
denote the size of the force on the two pistons. Since the person is placing all her weight on the first piston:
.
Since both pistons fit into cylinders, the two contact surfaces must be circles. Keep in mind that the area of a square is equal to
times its radius, squared:
.
.
By Pascal's Law, the pressure on the two pistons should be the same. Pressure is the size of normal force per unit area:
.
For the pressures on the two pistons to match:
.
,
, and
have all been found. The question is asking for
. Rearrange this equation to obtain:
.
Evaluate this expression to obtain the value of
, which represents the force on the piston with the larger diameter:
.
Answer:

Explanation:
Given data
λ=680nm
L=5.5m
ω=7.9cm=0.079m
To find
Width of slit a
Solution
As the single slit of width a has a bright central maximum of width:
ω=2λL/a
a=2λL/ω
Substitute the given values
So

Answer: B Genes make up chromosomes
