Radio waves travel at 3.00 · 108 m/s. Calculate the wavelength of a radio wave of frequency 900 kHz. (9.00 · 105 Hz.)_____ m

2.70 x 1014
3.70 x 10-15
3.33 x 102
3.00 x 10-3

Answers

Answer 1
Answer: v: velocity of wave
f: frequency 
L: wavelenght

v = fL => L = v/f => L = (3x10^8)/(900x10^3) => L = 3.33 x 10^2m

which situation involves shear? a. convergent boundaries b. isolated rift valleys c. volcanic mountain ranges d. frequent shallow earthquakes e. new rock formations

Answers

Answer:

Frequent shallow earthquakes

Explanation:

Shear is the response of a rock to deformation usually by compressive stress and forms particular textures.

During an earthquake when the earth shakes it produces a super shear earthquake in which the propagation of the rupture along the fault surface occurs at speeds in excess of the seismic shear wave (S-wave) velocity.

The mechanisms of shearing depend on the pressure and temperature of the rock and on the rate of shear which the rock is subjected to.

During the motion of the slinky in a transverse wave, what do the particles of the slinky coil do?Question 3 options:

the slinky particles move from the hand down the wave to the block


the slinky particles move side to side


the slinky particles move up and down

Answers

The characteristics of the traveling waves we can find the correct answer for the movement of the particles in the transverse wave is:

  • The slinky particles move up and down.

The traveling wave movement is a way of transmitting energy without mass movement, it is formed by two movements united, an oscillatory movement and a displacement movement, there are two possibilities:

  • Longitudinal wave. In this case, the oscillation of the particles is in the same direction as the movement of the wave.
  • Transversal wave. The oscillation of the particle is perpendicular to the movement of the wave, see attached.

In both cases, the matter particles are oscillating around their equilibriumposition and the wave is the one that has a displacement movement.

Let's review the claims:

a) False. The particle has an oscillatory motion, it does not have a net displacement

b) False. The movement is oscillatory

c) True. As the wave is transversal, the oscillatory movement from top to bottom.

In conclusion using the characteristics of the traveling waves we can find the correct answer for the motion of the particles in the transverse wave is:

  • the slinky particles move up and down

A car climbs 10.0 kilometers up a hill that inclines 8.0 degrees. What is the car's vertical displacement?

Answers

The correct answer to the question is : 1.392\ Km

CALCULATION:

The angle of inclination of the hill with the horizontal ground \theta =\ 8^(0).

The magnitude of displacement  or the distance travelled by the car up that hill is given as -

                        distance S = 10.0 Km.

We are asked to calculate the vertical displacement.

Applying vector resolution process, we get-

(a) Scos\theta is the horizontal component

 (b) Ssin\theta is the vertical component.

Hence, the vertical displacement is calculated as -

                        Vertical displacement S_(y) =\ S\sin\theta

                                                                    =\ 10* sin8^(0)

                                                                    = 1.392 Km.

Hence, the vertical displacement of the car is  1.392\ Km


A physical science test book has a mass of 2.2 kg what is the weight on mars??? please help

Answers

Weight is defined as a body's mass multiplied by its acceleration due to gravity.

Test Book's weight on mars = 8.1 N.

What is different between mass and weight?

  • The distinction between Mass and Weight is Weight is a measure of force, while mass is a measure of inertia. Many people use these two terms interchangeably.
  • The mass of a body is the amount of matter contained within it, whereas the weight of a body is the force acting on it as a result of gravity's acceleration. In chemistry, this is the primary distinction between mass and weight.
  • Weight is defined as a body's mass multiplied by its acceleration due to gravity.

Weight = (mass) x (gravity)

            = (2.2 kg) x (3.7 m/s^2)

              = 8.1 newtons
