If we took our laboratory spring to the moon, how accurately would it measure the mass? Why?

Physics

Accurately

Explanation:

If we took our laboratory spring to the moon, we can accurately measure the mass because mass of any substance is the same every where in the universe.

Mass is the amount of substance in a matter. Since the same substance on earth is made up of same matter on moon, the mass will remain the same.

  • The only difference between the measurement would be the weight.
  • Weight is the vertical force on an object.
  • It is function of mass and acceleration due to gravity.

Weight  = mass x acceleration due to gravity.

  • Acceleration due to gravity on earth and moon are different.
  • The gravity on moon is about one-sixth that on earth.
  • The weight using the same mass will be one-sixth
  • But the mass will be the same.

A phonograph record 0.15 m in its radius rotates 18 times per 90 seconds what is the frequency?
ioda

Answer:

The frequency of the phonograph record is 0.2 Hz

Explanation:

The frequency of an object moving in uniform circular motion is the number of completed cycles the object makes in a specified time period

The given parameters of the phonograph record are;

The radius of the record = 0.15 m

The number of times the phonograph record rotates, n = 18 times

The time it takes the phonograph record to rotate the 18 times, t = 90 seconds

The frequency of the phonograph record, f = (The number of times the phonograph record rotates) ÷ (The time it takes the phonograph record to rotate the 18 times)

∴ The frequency of the phonograph record, f = n/t = 18/(90 s) = 0.2 Hz

The frequency of the phonograph record = 0.2 Hz.

2.5 gram sample of a radioactive element was formed in a 1960 explosion of an atomic bomb at Johnson Island in the Pacific Test
kow [346]

Answer:

0.15625 grams

Explanation:

Half life: It is related to the decay of radioactive material. The duration in which  half of the material will be degraded/decayed. That means after half life 50% of the radioactive material will be left. Here the half life is 28 years.

Initial quantity of the sample: 2.5 grams.

After 28 years, the leftover quantity = 1.25 grams

After 56 years, the leftover quantity = 0.625 grams

After 84 Years, the leftover quantity = 0.3125 grams

After 112 years, the leftover quantity = 0.15625 grams

If an ideal gas does not exist then why laws were stated?
mihalych1998 [28]
That is because it is impossible to create a law for the behavior of every single different gas, so creating laws for an ideal gas helps us understand the basic nature of gasses which might or might not differ slightly or a lot. By understanding how an ideal gas works, we can understand how a normal gas works.
