What is the same person's mass on mars, where the acceleration due to gravity is 3.7 m/s2?

1 answer:

6 0

We can answer this even though you haven't told us anything from the previous problem that this one refers to. The person's mass stays the same as it was in the earlier problem, because mass is constant no matter where you take it.

A harmonic wave is traveling along a rope. It is observed that the oscillator that generates the wave completes 43.0 vibrations

blsea [12.9K]

Answer:

0.218

Explanation:

Given that

Total vibrations completed by the wave is 43 vibrations

Time taken to complete the vibrations is 33 seconds

Length of the wave is 424 cm = 4.24 m

to solve this problem, we first find the frequency.

Frequency, F = 43 / 33 hz

Frequency, F = 1.3 hz

Also, we find the wave velocity. Which is gotten using the relation,

Wave velocity = 4.24 / 15

Wave velocity = 0.283 m/s

Now, to get our answer, we use the formula.

Frequency * Wavelength = Wave Velocity

Wavelength = Wave Velocity / Frequency

Wavelength = 0.283 / 1.3

Wavelength = 0.218

Except when necessary for takeoff and landing, what is the minimum safe altitude required for a pilot to operate an aircraft ove

MAVERICK [17]

Except when necessary for takeoff and landing, <span>the minimum safe altitude required for a pilot to operate an aircraft over other than congested area is an altitude of 1000 ft above the highest obstacle within a 2000 ft horizontal radius of the aircraft.

It is also good to know that apart from taking off and landing, the aircraft must not operate at a distance less than 500 ft from any person, vessel, structure or vehicle.</span>

WILL MARK BRAINLIEST!!! Is string a ferromagnetic material?

Contact [7]

Answer:

See, the string is made of nickel and steel (iron+carbon), materials that are ferromagnetic. That is, a magnet attracts guitar strings. When this ferromagnetic metal vibrates in the magnetic field of the pickup, that disturbs the red field lines which also cross through the coil (not shown).
