Answer:

According to me, v=w×f is the correct formula...

Explanation:

v=w×f :-

where "v" is the waves velocity.
where "w" is the wavelength.
And where "f" is the frequency of the source.

What happens to the energy of a wave as it moves away from its source?

Eddi Din [679]

Answer:

As the particles move further away from their normal position (up towards the wave crest or down towards the trough), they slow down.

Explanation:

This means that some of their kinetic energy has been converted into potential energy – the energy of particles in a wave oscillates between kinetic and potential energy. Hope that this helps you and have a great day :)

An astronaut, whose mission is to go where no one has gone before, lands on a spherical planet in a distant galaxy.

Answer:

$M = 1.77 \times 10^{27} kg$

Explanation:

As we know that the that the Astronaut dropped a stone on the surface of the planet takes 0.420 s to fall a distance of d = 1.90 m

so we will have

$y = \frac{1}{2}g t^2$

$1.90 = \frac{1}{2}g(0.420^2)$

$g = 21.5 m/s^2$

now we know that the acceleration due to gravity is given as

$g = \frac{GM}{R^2}$

so we will have

$21.5 = \frac{(6.67 \times 10^{-11})M}{(7.40\times 10^7)^2}$

$M = 1.77 \times 10^{27} kg$

What would the single sample Cohen's d value be if the difference in sample mean and hypothesized mean was 16, and the sample st

ELEN [110]

Answer:

Explanation:

To calculate an effect size, called Cohen's d , for the one-sample t-test you need to divide the mean difference by the standard deviation of the difference, as shown below. Note that, here: sd(x-mu) = sd(x) . μ is the theoretical mean against which the mean of our sample is compared (default value is mu = 0).
