Why is the use of carbon-14 limited
Luden [163]

Carbon-14 is naturally created with the interaction of high-energy cosmic rays with atmospheric nitrogen. As part of the atmosphere, living organisms take in the carbon and incorporate this into living tissues. As long as the organism is alive and breathing, it keeps adding new carbon-14. When the organism dies, it stops gaining carbon-14 - or anything else, of course.


Carbon-14 is slightly radioactive, with a half-life of about 5700 years. If we assume that the atmospheric production of carbon-14 has been steady for the last 100,000 years, we can calculate the approximate age of when the organism died by determining what percentage of carbon-14 still exists in the dead material.


Paleo-archaeologists and anthropologists use this information when studying old cultures and civilizations.

A string is stretched to a length of 308 cm and both ends are fixed. If the density of the string is 0.023 g/cm, and its tension
soldi70 [24.7K]

Answer:

Frquency=3,994Hz

Explanation:

Tension =967N

Density of string (μ)=0.023g/cm

Length of the stretched spring=308cm

Fundamental frequency for nth harmonic :

Fn=n/2L(√T/μ)

Substituting the given values to find the frequency :

f1=1/2(308cm) *(0.01m/1cm)[(√967N)/(0.023g/cm)(0.1kg)/(0.1kg/m)/(1g/cm)]

=6.16m[(√967N)/0.0023kg/m)]

=3,994.20Hz

Approximately,

The frequency will be =3,994Hz

nexus9112 [7]

Answer:

See the explanation below.

Explanation:

53) Yes, this process is called latent heat transfer, it happens when heat is transferred to a body or a substance, an increase in its energy is observed without presenting an increase in temperature. An example of this can be seen in the evaporation of water.

54) It absorbs energy since heat transfer always occurs from a space of higher temperature to another with lower temperature so as the wax freezes the heat is transferred from the environment to the wax.

55) The water vapor and wet air will be absorbed by the canvas, the heat contained in this water vapor will be absorbed by the canvas in this way decreases the temperature of the water inside the canteen.

56) The process is vaporization. The refrigerant of the air conditioning equipment enters the coil, in the form of liquid, this liquid is at low temperature, so that the room air at a higher temperature, exchanges heat with the refrigerant liquid, the refrigerant liquid changes the phase of liquid to vapor, for when it is completely vaporized this can be sucked by the compressor equipment.
