Two similar waves X and Y travel through the same medium. Wave X has a frequency of 200 hertz and a

Physics
1 answer:
velikii [3]3 years ago
4 0

Answer:

The correct solution is option A "10 meters".

Explanation:

The given values are:

Wave X,

Frequency,

F_x=200 \ H_z

Wavelength

\lambda_x=35 \ m

Wave Y,

Frequency,

F_y=700 \ Hz

Let its wavelength = \lambda_y

As we know,

⇒  v=f \lambda

For both waves, medium is same then

⇒  v_x=v_y

⇒  f_x \lambda_x=f_y \lambda_y

then,

⇒  \lambda_y=\frac{f_x \lambda_x}{f_y}

On substituting the estimated values in the above equation, we get

⇒      =\frac{200\times 35}{700}

⇒      =\frac{7000}{700}

⇒      =10 \ m

Calculate the energy released by the electron-capture decay of 5727Co. Consider only the energy of the nuclei (ignore the energy
erma4kov [3.2K]

Answer:

Explanation:

⁵⁷Co₂₇  + e⁻¹  =  ²⁷Fe₂₆

mass defect = 56.936296 + .00055 - 56.935399

= .001447 u

equivalent energy

= 931.5 x .001447 MeV

= 1.3479 MeV .

= 1.35 MeV

energy of gamma ray photons = .14  + .017

= .157 MeV .

Rest of the energy goes to neutrino .

energy going to neutrino .

= 1.35 - .157

= 1.193 MeV.

Two equipotential surfaces surround a +3.10 x 10-8-c point charge. how far is the 290-v surface from the 41.0-v surface?
MrMuchimi
 T<span>he equation to be used here to determine the distance between two equipotential points is:
V = k * Q / r 

where v is the voltage of the point, k is a constant, Q is charge of the point measured in coloumbs and r is the distance. 
In this case, we can use ratio of proportions to determine the distance between the two points. in this respect, 

Point 1: 
V = k * Q / r = 290
r = k*Q/290 ; kQ = 290r

Point 2:
V = k * Q / R = 41
R = k*Q/41
from equation 10 kQ = 290r
R = 290/(41)= 7.07 m 
The distance between the two points then is equal to 7.07 m.

How do I calculate speed, velocity, and acceleration? I need the formulas too
vodomira [7]
Speed is the secular unit, which means it only measures "how fast it goes."
speed= \frac{distance}{time}
Velocity is a victory unit, which means it measures "both how fast it goes AND the direction."
velocity= displacement/time
Acceleration is the change of velocity over time. 
acceleration =  \frac{change in velocity}{time}
