What is the wave speed of a wave that has a frequency of 25 Hz and a wavelength of 0.80 m?
tatuchka [14]

Answer:

Speed = 20 m/s

Step-by-step explanation:

The formula to find the speed of a wave is found by

Speed = Wavelength x Frequency  where the frequency is in HZ and the wavelength is in meters

Speed =  .80*25

Speed = 20 m/s

Afina-wow [57]

Answer:

major arc CEB = 320°

Step-by-step explanation:

arc BF = 140°

arc CE = 140°

arc CB = arc EF

arc CB + arc EF = 360-280 = 80

arc CB = 40°

major arc CEB = 360 - 40= 320°

Pyramid A and Pyramid B are similar. Pyramid A has a volume of 648 m and Pyramid B has a
ryzh [129]

Answer:

the ratio of the surface area of Pyramid A to Pyramid B is: \frac{36}{49}

Step-by-step explanation:

Given the information:

  • Pyramid A :  648 m^{3}
  • Pyramid B : 1,029 m^{3}
  • Pyramid A and Pyramid B are similar

As we know that:

If two solids are similar, then the ratio  of their volumes is equal to the cube

of the ratio of their corresponding  linear measures.

<=> \frac{Volume of A }{Volume of B} =(\frac{a}{b}) ^{3} =  \frac{684}{1029} = \frac{216}{343}

<=> \frac{a}{b} =\frac{6}{7}

Howver, If two solids are similar, then the n ratio of their surface areas is equal  to the square of the ratio of their  corresponding linear measures

<=> \frac{surface area of A}{surface area of B}  =( \frac{a}{b}) ^{2}

= \frac{36}{49}

So  the ratio of the surface area of Pyramid A to Pyramid B is: \frac{36}{49}
