Explanation:
Given
Dimension of Plastic sheet is
Charge on sheet
Charge density
Sphere has mass of
If sphere is suspended motionless then its weight is balanced by repulsion force
Repulsive force
where E=Electric field due to sheet
1.Vitamin C (ascorbic acid)
Chemical formula of vitamin C is C6H8O6
Two elements found in vitamin C are Carbon and Hydrogen
2. Vitamin B12 (Cyanocobalamin)
Chemical formula of vitamin B12 is C63H88CoN14O14P
Two elements found in vitamin B12 are Phosphorous and Cobalt. Of these two elements, Cobalt is a trace element and is found right at the center of this vitamin.
3. Vitamin E (alpha-Tocopherol)
Chemical formula of vitamin E is C29H50O2
Two elements found in vitamin E are Hydrogen and Oxygen.
Answer:
One way to test the hypothesis is to create two waves, one in the air and one on the ground at the same time. One of them for the elephant to get closer and another for the elephants to move away. Observe the reaction of the animal and with this we know which sound came first.
Explanation:
This hypothesis is based on the fact that the speed of sound in air is v = 343 m / s with a small variation with temperature.
The speed of sound in solid soil is an average of the speed of its constituent media, giving values between
wood 3900 m / s
concrete 4000 m / s
fabrics 1540 m / s
earth 5000 m / s wave S
ground 7000 m / s P wave
we can see that the speed on solid earth is an order of magnitude greater than in air.
One way to test the hypothesis is to create two waves, one in the air and one on the ground at the same time. One of them for the elephant to get closer and another for the elephants to move away. Observe the reaction of the animal and with this we know which sound came first.
From the initial information, the wave going through the ground should arrive first.

Explanation:
As we know our atmosphere or air have different levels. Every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
I believe it's DNA.
Here're some sentences to explain:
Genetic material, also known as deoxyribonucleic acid<span> (</span>DNA<span>) and </span>Ribonucleic acid<span> (</span>RNA<span>), plays a fundamental role in the composition of living organisms.</span>
