Mass of the astronaut on the moon is 61.22 because the acceleration due to gravity on the surface of the moon is about 1/6 that on the surface of earth.

Gravitational acceleration is the acceleration gained by an object due to the force of gravity.

Weight of the astronaut on the Earth = w = 600 N

Mass of the astronaut on the Earth = w/g

Mass m = 600/9.8

m = 61.22 kg

Mass of the astronaut will remain same on the Moon but the weight will change due to the change in the acceleration due to gravity on the surface of the moon.

Acceleration due to gravity on the surface of the moon is about 1/6 that on the surface of earth i.e. g' = g/ 6

g' = 9.81/6

g' = 1.63

Weight of the Astronaut on the surface of the moon = m * g'

The position versus time plot of driven harmonic motion when the driving frequency is slightly higher than the theoretical natural frequency will show a sinusoidal oscillation with a gradually increasing amplitude.

What is harmonic?
A harmonic wave, like a sinusoidal wave, has a frequency that is an integer multiple of the basic frequency, or the frequency of the initial periodic signal. The first harmonic of the original signal is also referred to as that; higher harmonics are the other harmonics. The sum of harmonics is periodic at the fundamental frequency because all harmonics are at that frequency as well. A harmonic series is formed by the group of harmonics.

The phrase is used in a variety of fields, including radio technology, physics, acoustics, power electronics transmission, and music. For instance, if indeed the frequency response is 50 Hz, which is a typical AC power supply frequency, the first three higher harmonics' frequencies are 100 Hz (second harmonic), 150 Hz, and 200 Hz (3rd harmonic).

As the driving frequency increases, the amplitude of the oscillation will become more pronounced and eventually reach a peak before decaying back to the original amplitude. The period of the oscillation will remain constant, even as the amplitude increases.

What is impurities?
Impurities seem to be chemical substances that differ from of the chemical composition of the substance or compound and are contained within a small volume of liquid, gas, or solid in chemistry as well as materials science. A pure chemical should, first and foremost, thermodynamically exist in at least each chemical step and also be distinguishable by its one-component phase diagram. Second, a pure chemical should, in practise, show to be homogeneous. All attempts as well as tests at further purification and separation will fail with the ideal pure chemical. Thirdly, it should be completely free of all traces of any other chemical species. Here, we concentrate on the common chemical definition.

Impurities can cause irregularities in the object's surface or internal structure, which can lead to inaccurate measurements. Impurities can also interfere with the accuracy of tests that measure physical or chemical properties of the object, such as its density or its electrical conductivity. Furthermore, impurities can lead to contamination of the measuring tools themselves, which can cause inaccurate results.

The speed of the satellite at perigee is 7074.27 m/s

What is satellite?
An object that has been placed into orbit in space on purpose is known as a satellite as well as artificial satellite. Most satellites, with the exception of passive satellites, have a means of generating electricity for the equipment they carry, such as solar panels as well as radioisotope thermoelectric generators (RTGs). The majority of satellites also have transponders, which are a type of ground station communication system. The most common satellites, small CubeSats, use a standardised bus to reduce costs and labour. Satellites of a similar type can cooperate with one another to form constellations. Satellites are made to be as light and durable as possible due to the high cost of space launch. Numerous transponders, with a bandwidth of dozens of megahertz, are carried by the majority of communication satellites, which are radio relay channels in orbit.

The speed of the satellite at perigee can be calculated using the equation of conservation of energy:
e = (½) mv2 - G(Mm/r)

Where e is the total energy of the satellite, m is its mass, v is its velocity, G is the gravitational constant, M is the mass of the Earth, and r is its distance from the Earth's center.

At apogee, the total energy of the satellite is:
e1 = (½) mv12 - G(Mm/r1)

At perigee, the total energy of the satellite is:
e2 = (½) mv22 - G(Mm/r2)

Equating the two expressions, we get:
(½) mv12 - G(Mm/r1) = (½) mv22 - G(Mm/r2)

Substituting the given values, we get:
(½)(6260 m/s)2 - G(Mm/2500 km) = (½) mv22 - G(Mm/500 km)

Rearranging the equation, we get:

mv22 = (½)(6260 m/s)2 - G(Mm/2500 km) + G(Mm/500 km)

Taking the square root of both sides, we get:
v2 = √[(½)(6260 m/s)2 - G(Mm/2500 km) + G(Mm/500 km)]

Finally, we get:
v = √[(½)(6260 m/s)2 - G(Mm/2500 km) + G(Mm/500 km)]

Therefore, the speed of the satellite at perigee is:
v = √[(½)(6260 m/s)2 - G(Mm/2500 km) + G(Mm/500 km)] ≈ 7074.27 m/s
