A room has a volume of 160 m3. An air-conditioning system is to replace the air in this room every 21.3 minutes, using ducts tha
serious [3.7K]

Answer:

A. 0.204203928 m

b. 0.1443939822

Explanation:

Givens:

Volume (V) = 160 m^3

velocity 1 (v1) = 3.00 m/s

velocity 2 (v2) = 6.00 m/s

Time (t) = 21.3 minutes = 1278 seconds

Side length = ?

V = A*v*t

A = s^2

V = s^2*v*t

s= \sqrt{\frac{V}{v*t} }

A.

s = \sqrt{\frac{V}{v*t} } = \sqrt{\frac{160}{3.00*1278} } = 0.204203928 m

B.

s = \sqrt{\frac{V}{v*t} } = \sqrt{\frac{160}{6.00*1278} } = 0.1443939822 m

I hope this helped!! Have a good day.

Radio waves are<br> waves.<br> O longitudinal<br> O transverse<br> O mechanical
EleoNora [17]

Answer:

Transverse

Explanation:

Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves

An ice skater is spinning at 6.00 rev/s with his moment of inertia being 0.400 kg/m2. Calculate his new moment of inertia if he
labwork [276]

Answer:

New moment of inertia will be I=1.92kgm^2

Explanation:

It is given initially angular velocity \omega =6rev/sec=6\times 2\pi =37.68rad/sec

Moment of inertia I=0.4kgm^2

Angular momentum is equal to L=I\omega =37.68\times 0.4=15.072kgm^2/sec

Now angular velocity is decreases to \omega =1.25rev/sec=1.25\times 2\times 3.14=7.85rad/sec

As we know that angular momentum is conserved

So 15.072=I\times 7.85

I=1.92kgm^2

So new moment of inertia will be I=1.92kgm^2

Thickness of the filmThe UC Davis physicist measures the thickness of a layer of a benzene with nb= 1.50 by shiningmonochromatic
ANEK [815]

Answer:

Explanation:

  • Given λ = wavelength of light reflected = 635 nm
  • Using the equation ; 2 nb t = (m - (1/2)λ
  • nb= 1.50

Plugging the values in the equation ;

  • 2 (1.50) t = (1 - (1/2) (635)
  • t = 105.83 nm = the minimum thickness of the film

b) To calculate the wavelength of the most reflected visible light ;

  • From the equation 2 nb t = mλ
  • λ' =  2 nb t/m

Plugging the values into the equation

  • 2 (1.50) (105.83) = λ'
  • λ' = wavelength = 317.5 nm
