show that for a clósed organ pipe only odd harmonics are present wheras for an open organ pipe all the harmonics are present
Answer:
For a closed organ pipe, the point at the closed end is always a node, 'N' while the open end is always an antinode, 'A'
Therefore, for a closed organ pipe, we only have;
NA = N↔A = First harmonics = f₁
NANA = NA↔AN↔ NA = Third harmonics, = f₃ = 3·f₁
NANANA = NA↔AN ↔ NA ↔ AN ↔ NA = f₅ = 5·f₁
It can also be shown that for a closed organ pipe, only f₇, f₉, f₁₁, ... are present
Therefore, a closed organ pipe has only odd harmonics present
For an open organ pipe, we have;
ANA = First harmonics = f₁
ANANA = ANA ↔ ANA = Second harmonics = f₂ = 2·f₁
ANANANA = ANA ↔ ANA ↔ ANA = Third harmonics = f₃ = 3·f₁
Similar relationship exist for f₄, f₅, f₆...
Therefore, for an open organ pipe, all harmonics, (multiples of the fundamental, f₁) are present

What is one way that nuclear fusion differs from nuclear fission?
A. Nuclear fusion requires very high pressures and temperatures.
B. Nuclear fusion occurs spontaneously on Earth.
C. Nuclear fusion is used in power plants to produce electricity.
D. Nuclear fusion is used to power aircraft carriers.
Answer:
A. Nuclear fusion requires very high pressures and temperatures.
Explanation:
Nuclear fusion requires very high pressures and temperatures is one way that nuclear fusion differs from nuclear fission. Hence option A is correct.
What is nuclear fusion and fission ?Nuclear fission and fusion processes are the two basic types of nuclear reactions. Nuclear fusion is a process in which two or more light nuclei collide to generate a heavier nucleus. Nuclear fusion occurs in elements with a low atomic number, such as hydrogen. Nuclear fusion is the inverse process of nuclear fission, in which heavy atoms disperse and generate lighter elements. Nuclear fusion and fission both yield enormous amounts of energy.
A nuclear process in which atomic nuclei of low atomic number fuse to generate a heavier nucleus, releasing energy.
Because of nuclear fusion, every star in the cosmos, including the sun, is alive. They generate massive amounts of heat as a result of this activity.
Fission is a nuclear process that occurs when a heavy nucleus breaks spontaneously or when it collides with another particle, releasing energy. Nuclear fission occurs when the nucleus of an atom breaks into lighter nuclei as a result of a nuclear reaction. This decay can occur naturally as a result of radioactive decay, or it can be replicated in a laboratory by attaining the requisite circumstances (bombarding with neutrinos). The resultant pieces have a lower total mass than the original. In the preceding process, the missing mass is turned into nuclear energy.
Hence option A is correct. it requires high pressure and high temperature and it occurs in sun.

Answer:
The correct option is;
The assertion is correct, but reason wrong
Explanation:
The question is with regards to the relationship between work, energy, power, and velocity
The mass of each of the persons running up the staircase = Different
The time it takes each person to run up the stairs = Equal time
Let, 'm₁' and 'm₂' represent the mass of each of the persons that ran up the stairs and m₁ > m₂
Let 't' represent the equal time it takes then to run up the stairs
Let 'h' represent the height of the stairs
The energy, 'E', it takes to run up the stairs is equal to the potential energy, P.E., obtained at the top of the stairs
P.E. = m·g·h
Where;
m = The mass of the person at an elevated height
g = The acceleration due to gravity = Constant
h = The height reached above ground level
Given that the height reached is the same for both of the persons, we have
For m₁, P.E.₁ = m₁·g·h and for m₂, P.E.₂ = m₂·g·h
Therefore, where, m₁ > m₂, we have;
P.E.₁ > P.E.₂
∴ E₁ > E₂
Power, 'P', is the rate at which energy is expended
∴ Power, P = E/t
∴ P₁ = E₁/t > P₂ = E₂/t
Therefore, the person with the greater mass, 'm₁', uses more power than the person of mass 'm₂', in running up the stairs
Therefore, the assertion is correct
The average velocity, vₐ = (Total distance traveled, d)/(Total time taken, t)
Given that the distance, 'd', covered in running up the stairs by both persons is the same, and the time it takes them to complete the distance, 't', is also the same, we have;
The average velocity of the person with the greater mass m₁ is the same as the average velocity of the person with mass, m₂
Therefore, the reason is wrong
The answer is that the assertion is correct, but reason wrong

An astronaut has a mass of 70kg.
The force of gravity on the Moon is approximately 1.5N/kg.
Calculate the weight of the astronaut when they are on the Moon.
Weight = .............................................................. N
Answer:
Weight = 105 Newton
Explanation:
Given the following data;
Mass = 70kg
Force of gravity = 1.5N/kg
To find the weight;
Weight = mass * force of gravity
Substituting into the equation, we have;
Weight = 70 * 1.5
Weight = 105 Newton
Therefore, the weight of the astronaut when they are on the Moon is 105 Newton.
