PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! Which wave has the greatest frequency?

Physics
1 answer:
SCORPION-xisa [38]3 years ago
3 0

Answer: Option (4) is the correct answer.

Explanation:

Number of waves that pass through a given point in a per unit time is defined as frequency.

Therefore, when each crest or trough of a wave are closer then it means frequency of the wave is greatest. Whereas when each crest or trough of a wave are far away from another crest or trough of the same wave then it means frequency of wave is the smallest.

Thus, we can conclude that out of the given waves, option four displays a wave with greatest frequency.

If the pressure of gas is doubled and its absolute temperature is quadrupled, the volume is what factor times the original?
Lapatulllka [165]

Answer:

Volume will increase by factor 2

So option (A) will be correct answer  

Explanation:

Let initially the volume is V pressure is P and temperature is T

According to ideal gas equation PV=nRT, here n is number of moles and R is gas constant

So V=\frac{nRT}{P}....................eqn 1

Now pressure is doubled and temperature is quadrupled

So new volume V_{new}=\frac{nR4T}{2P}=\frac{2nRT}{P} ........eqn 2

Now comparing eqn 1 nad eqn 2

V_{new}=2V

So volume will increase by factor 2

So option (A) will be correct answer

Tcecarenko [31]

Answer:

Explanation:

Assuming that velocities remain negligible,

The work will be equal to the change in potential energy of the center of mass

mass is 30 m(5 kg/m) = 150 kg

W = 150(9.8)(30/2) = 22,050 J ≈ 22 kJ

When cs-137 decays, it emits gamma radiation. the energy of one photon is 1.06 × 10-13 j. what is the wavelength of this radiati
Kryger [21]
To find the solution to the problem, we would be using Planck's equation which is E = hv
Where:
E = energy
h = Planck's constant = 6.626 x 10-34 J·s
ν = frequency
Then, you’ll need a second equation which is c = λν
Where:
c = speed of light = 3 x 108 m/sec
λ = wavelength
ν = frequency
Reorder the equation to solve for frequency:ν = c/λ
Next, substitute frequency in the first equation with c/λ to get a formula you can use:
E = hν
E = hc/λ
But we are looking for the wavelength, so rearrange it more, then our final equation would be:
λ = hc / E 
λ = (6.625E-34)(3.0E8 m/s) / (1.06E-13) 
λ = 1.875E-12 m
