Answer:

60.905 kg!

Explanation:

The formula is m = 2KE / v^2 (m= mass, KE= kinetic energy, v= velocity)

m = 2(955) / 5.6^2

m = 1910 / 31.36

m = 60.905 kg

An organ pipe open at both ends has a radius of 4.0 cm and a length of 6.0 m. what is the frequency (in hz) of the third harmoni
Marysya12 [62]

When air is blown into the open pipe,

L = \frac{nλ}{2}

where nis any integral number 1,2,3,4 etc. and λ is the wavelength of the oscillation

⇒λ=\frac{2L} {n}

Note here that n=1 is for fundamental, n=2 is first harmonic and so on..

⇒ third harmonic will be n=4

Given L=6m, n=4, solving for λ we get:

λ=\frac{(2)*(6)}{4} =3m

Relationship of frequency(f), velocity of sound (c) and wavelength(λ) is:

c=f.λ Or f= \frac{c}{λ}

⇒f=\frac{344}{3}

≈115 Hz

17. The Earth exerts a gravitational force of 0.750 N on an object.
n200080 [17]

Answer:

0.076 kg

Explanation:

The force created by gravity can be found using mass x (9.8 m/s^2).

mg=0.750 N

m(9.8) = 0.750

Multiply both sides by 9.8: m = 0.076 kg

Conservation of energy
ddd [48]

<u>Answer:</u>

  • It is the fundamental concept of physics.
  • It states that total amount of energy in a system remains constant in isolated system. This means energy can neither be created nor it can be destroyed but can change from  one form to another.
  • Energy can change from kinetic to potential energy, and back without reducing the total energy.

The carbon cycle is powered by which two processes?
Arada [10]

Answer:

the answer is the last one

Explanation:

here is the definition:

(i know how to explain the answer, its merely unnecessary being that there is an offical definition.)

<em>the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.</em>
