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 :)

Determine whether the statement is true or false. If f '(c) = 0, then f has a local maximum or minimum at c.
ankoles [38]

It is False that, If f '(c) = 0, then f has a local maximum or minimum at c.

Local maximum and minimum points are very distinctive on the graph of a function and are thus, helpful in grasping the shape of the graph. Either a local minimum or a local maximum can be considered a local extremum.

A counterexample can be used for:

f(x) = x³

f'(x) = 2 × x²

and,

f'(0) = 2×0² = 0

However, the assertion is false because x = 0 is actually an inflection point rather than a maximum or minimum in f(x) = x³.

Sever21 [200]

Answer:

v = 20\pi sec^2\theta

Explanation:

As we know that the angle made with the vertical is given so we have

tan\theta = \frac{x}{10}

so we have

x = 10 tan\theta

now differentiate both sides with time

v = \frac{dx}{dt} = 10 sec^2\theta \frac{d\theta}{dt}

v = 10 \omega sec^2\theta

now we know that

\omega = 2\pi f

\omega = 2\pi (\frac{60}{60})

\omega = 2\pi

now we have

v = 10(2\pi) sec^2\theta

v = 20\pi sec^2\theta
