The relationship between distance from the sun and orbital period is that as the distance from the sun increases, the orbital pe

riod increases.
We can see this because as we go through the planets in our solar system, the farther away they are from the Sun, the longer their orbital period becomes. For example, Mercury is about 67 million km away from the Sun and has an orbital period of 88 days, where as Neptune is about 4.5 billion km away from the Sun and has an orbital period of 165 years.

This tells us that as the distance from the sun increases, gravity _________________. Because gravity _______________, the orbital period is __________________.

You are given an unknown solid substance of mass 500 g and you want to estimate its specific heat. unfortunately, you don’t have
Julli [10]

Answer:

Option C) 2,090 J/(mol K)

Explanation:

Data:

Volume in the beaker = 429 ml

temperature  = 20° C

Density = 789 kg/m³

Equilibrium reading = 429

volume change = 29 ml

                          = 0.029 L

Energy change = mcΔT

A stone is dropped from the top a 45m hign building how fast will it moving when it reaches the ground? Ande what will its veloc
posledela

Answer:

29.7 m/s fast, velocity is 29.7 m/s

Explanation:

Applying,

v² = u²+2gs...................... Equation 1

Where v = final velocity, u = initial velocity, g = acceleration due to gravity, s = distance.

Given: u = 0 m/s (dropped from height), s = 45 m

Constant: g = 9.8 m/s²

Substitute these values into equation 1

v² = 0²+2×9.8×45

v² = 882

v = √(882)

v = 29.7 m/s.

Hence the stone will be moving 29.7 m/s fast and the velocity is also 29.7 m/s

Water waves that you might see at the beach move in circular or elliptical paths. What type of mechanical waves are water waves?
vazorg [7]

To find:

Which type of mechanical wave is a water wave?

Explanation:

The water wave is a combination of longitudinal and transverse waves. They are a type of wave called surface waves. The surface waves are the waves that transmit energy in the interface between two mediums.

Final answer:

Thus the correct answer is option C.

A tightly wound toroid of inner radius 1.2 cm and outer radius 2.4 cm has 960 turns of wire and carries a current of 2.5 A.
OLEGan [10]

Answer:

a

  B  = 0.0533 \ T

b

  B  =  0.04 \ T

Explanation:

From the question we are told that

   The inner radius is r = 1.2 \ cm = 0.012 \ m

   The  outer radius is  r_o  =  2.4 \ cm  =  \frac{2.4}{100} =  0.024 \ m

    The nu umber of turns is  N  =  960

    The current it is carrying is  I =  2. 5 A

Generally the magnetic field is mathematically represented as

      B  =  \frac{\mu_o  *  N* I  }{2 * \pi * r  }

Where  \mu_o is the permeability of free space with a constant value    

            \mu  =   4\pi * 10^{-7} N/A^2

And the given distance where the magnetic field is felt is  r =  0.9 cm  =  0.009 m

Now  substituting values

     B  =  \frac{  4\pi * 10^{-7}  *  960* 2.5  }{2 * 3.142 * 0.009  }

    B  = 0.0533 \ T

    Fro the second question the distance of the position considered from the center is  r =  1.2 cm  =  0.012 m

So the  magnetic field is  

        B  =  \frac{  4\pi * 10^{-7}  *  960* 2.5  }{2 * 3.142 * 0.012  }

        B  =  0.04 \ T
