What is the speed of a wave frequency of 300hz and a wavelength of 25M

Physics
1 answer:
tia_tia [17]3 years ago
8 0

Answer:

7500 m/s

Explanation:

We can use the equation velocity of a wave equals wavelength times  frequency.  Therefore, v = wavelength*f = (25 m)(300 Hz) =  m/s7,500

For a Physics course containing 10 students, the maximum point total for the quarter was 200. The point totals for the 10 studen
Talja [164]

Answer:

130.5

Explanation:

According to the stemplot attached (Which I think it is, and if not, then you only need to replace the procedure with your data and you should be fine), you need to calculate first the points of all ten students. In that plot, we can easily calculate the points.

The first number in the colum represents the centen of the point, while the numbers of the second column, represents the units of that centen, for example if you see:

16 | 8 5 6

This means that the point for the students are 168, 165 and 166. Three students, three points.

If you watch the stemplot, the points for the students are:

116, 118, 121, 124, 128, 133, 137, 142, 146 and 179.

The median can be calculated using the mean between the two values in the middle of the sequence.

In this case, half of ten is 5, so, the numbers from the middle in this sequence are 128 and 133, therefore:

Median = 128 + 133 / 2 = 130.5

SOMONE PLEASE HELP ASAP!!!!
Anna11 [10]

Answer:

from vacuum to air

Explanation:

Refraction is a property of lightwave, in which it changes speed as it passes the boundary between two media.

  • When light travels from a denser medium to a less dense medium, the light wave speeds up and bends away from the normal.
  • Also when light travels from a less dense medium to a denser medium, the light wave slows down and bends toward the normal.

The correct option must be from a less dense medium to a denser medium.

density of glass = 2500 kg/m³

density of air = 1.275 kg/m³

density of ice = 919 kg/m³

density of water = 1000 kg/m³

density of plastic = 940 kg/m³

density of vacuum = 6.5 x 10⁻²⁷ kg/m³

The two possible options are;

from ice to water

from vacuum to air

The difference in densities of ice and water is not larger compared to vacuum and air.

If you are required to choose two options, the two options are correct

But if it is only one option, then from vacuum to air is the correct answer.

Therefore, the correct option is from vacuum to air
