Answer is: <span>Distance between the sun and Earth

Explanation:
</span><span>Distance between Earth and Saturn is not correct answer because this distance varies greatly. When comparing distance we need some distance that is pretty much the same all the times. This is why distance between the sun and Earth is chosen to meassure distances in solar system.
Answers "</span>Speed of rotation of Saturn" and "<span>Speed of rotation of Earth" are not correct because they represent speed which can not measure distance.</span>

Answer:

Distance between earth and sun.

Explanation:

The distance between earth and sun is used to compare the distance between the objects in our solar system. It is because the distance between earth and sun is called as one Astronomical unit.

1 Astronomical unit (AU) is equal to 149,597,870.7 Km.

It is the mean distance between earth and sun.

The time taken by light to cover 1 Astronomical Unit is 499 seconds.

This is a big unit of distance.

A traveling wave on a string can be described by the equation : y = (5.26 ~\text{m}) \cdot \sin \big( (1.65 ~\frac{\text{rad}}{\
zloy xaker [14]

Answer:

  t = 1.77 s

Explanation:

The equation of a traveling wave is

       y = A sin [2π (x /λ -t /T)]

where A is the oscillation amplitude, λ the wavelength and T the period

the speed of the wave is constant and is given by

      v = λ f

Where the frequency and period are related

     f = 1 / T

we substitute

      v = λ / T

let's develop the initial equation

    y = A sin [(2π / λ) x - (2π / T) t +Ф]

where Ф is a phase constant given by the initial conditions

the equation given in the problem is

    y = 5.26 sin (1.65 x - 4.64 t + 1.33)

if we compare the terms of the two equations

 

         2π /λ = 1.65

          λ = 2π / 1.65

          λ = 3.81 m

         2π / T = 4.64

          T = 2π / 4.64

          T = 1.35 s

we seek the speed of the wave

           v = 3.81 / 1.35

           v = 2.82 m / s

           

Since this speed is constant, we use the uniformly moving ratios

          v = d / t

           t = d / v

           t = 5 / 2.82

           t = 1.77 s

PLEASEEE HELPPP!!!!
Zigmanuir [339]

Answer: The work is 1863 N*m

Explanation:

We can define work as:

W = F*d

Where F is the force that the mover needs to apply to the refrigerator, and d is the distance that the refrigerator is moved.

To move the refrigerator, the minimal force that the mover needs to do is exactly the friction force (In this case, the refrigerator will move with constant speed).

Then we will have:

F = 230 N

and the distance is 8.1 meters, then the work will be:

W = 230N*8.1 m = 1863 N*m
