What is the wavelength of radar waves with the frequency of 6.0 x 10 ^10 Hz?

Which effect is created when two sound waves that are close in pitch

Temka [501]

Answer:

C. Beats

Explanation:

When waves are interfering with each other, the sound is louder in some places and softer in others. As a result, we hear pulses or beats in the sound.

Rocks within Earth both expand and contract as P waves pass

Explanation:

Rocks within the earth both expands and contracts as P-waves passes through them. P-waves are elastic waves.

Elastic waves behaves in such a way that they do not cause permanent deformation of rocks.
They can be said to cause elastic deformation when they travel through rocks.
They simply temporarily expand and contract the rock within a short period by causing the vibration of particles of the medium.
After a short while, the rock returns back to its original position as if nothing has happened to it.
These elastic waves are better called seismic waves.
P-waves are primary waves that can travel through any medium.

A particle moves along the x axis from the origin. The magnitude of the position vector at time t is

Maurinko [17]

1) The average velocity is $-2.1\cdot 10^5 m/s$

2) The instantaneous velocity is $64t-260t^3$

Explanation:

1)

The average velocity of an object is given by

$v=\frac{d}{t}$

where

d is the displacement

t is the time elapsed

In this problem, the position of the particle is given by the function

$x(t) = 32t^2 - 65t^4$

where t is the time.

The position of the particle at time t = 6 sec is

$x(6) = 32(6)^2 - 65(6)^4=-83,088 m$

While the position at time t = 12 sec is

$x(12)=32(12)^2-65(12)^4=-1,343,232 m$

So, the displacement is

$d=x(12)-x(6)=-1,343,232-(-83,088)=-1,260,144 m$

And therefore the average velocity is

$v=\frac{-1,260,144 m}{12 s- 6 s}=-2.1\cdot 10^5 m/s$

2)

The instantaneous velocity of a particle is given by the derivative of the position vector.

The position vector is

$x(t) = 32t^2 - 65t^4$

By differentiating with respect to t, we find the velocity vector:

$v(t) = x'(t) = 2\cdot 32 t - 4\cdot 65 t^3 = 64t - 260 t^3$

Therefore, the instantaaneous velocity at any time t can be found by substituting the value of t in this expression.

Select all that apply. Which of the following are characteristics of acids? contain hydroxide ion or produce it in a solution ta

julia-pushkina [17]

These are the characteristics that apply:

- In a solution taste sour: which is consequence of the H+ concentration.

- Corrode metals: the H+ ion reacts with the metal producing a salt and water

-Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+. This proton will react with H2O to form H3O+ (hydronium), as per this scheme:

HA + H2O --> A(-) + H3O(+)
