Answer:

There are eight planets in the solar system. Four of them are inner and other four are outer planets.

→Outer planets lie beyond asteroid belt.

→Outer planets are gaseous planets and are referred as Jovian planets. Inner planets are terrestrial planets.

→Outer planets have many number of moons where as inner planets have zero to two moons.

→Inner planets lie closer to the Sun as compared to Outer planets.

→Outer planets are larger in size than inner planets.

→ Outer planets have larger orbital period than inner planets.

→Outer planets have ring system unlike inner planets.

Answer:

The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune.

A boy swings a ball on a string at constant speed in a circle that has a circumference equal to 6 m. What is the work done on th
Grace [21]

Answer:

0 J

Explanation:

From the diagram below; we would notice that the Force (F) = Tension (T)

Also the angle θ adjacent to the perpendicular line = 90 °

The Workdone W = F. d

W = Fd cos θ

W = Fd cos 90°

W = Fd (0)

W = 0 J

Hence the force is perpendicular to the direction of displacement and the net work done in a circular motion in one complete revolution is = 0

Using the result of the preceding problem, (a) calculate the distance between fringes for 633-nm light falling on double slits s
vekshin1

To solve this problem it is necessary to apply the concepts related to the concept of superposition and the fringe separation for double slit experiment.

The equation can be written as

\Delta y = \frac{x\lambda}{d}

Where

\Delta y = Distance between fringes

x = distance between slits and screen

d = Distance between slits

\lambda= Wavelength

Our values are given as

d= 0.08mm

x =3m

\lambda = 633nm

In this way replacing in the equation,

\Delta y = \frac{x\lambda}{d}

\Delta y = \frac{3m(633nm*(\frac{1*10^{-9}}{1nm}))}{0.08*(\frac{1*10^{-3}m}{1mm})}

\Delta y = 2.37*10^{-2}m

\Delta y = 2.37cm

Therefore the distance between the fringes is 2.37cm

PART B) For the case in which it is submerged in water it is necessary to apply the relationship of the fringes with the index of refraction therefore

\Delta Y_2 = \frac{\Delta Y_1}{n}

\Delta Y_2 = \frac{2.37}{1.33}

\Delta Y_2 = 1.78cm

Which is colder, 0°C or 20°F?
Mashutka [201]

In order to compare the two temperatures, we need to convert 20°F into Celsius. The formula we need to use is:

T(^{\circ}C)=\frac{5}{9}(T(^{\circ}F)-32)

Substituting 20°F, we find

T(^{\circ}C)=\frac{5}{9}(20^{\circ}F-32) =-6.7^{\circ}C


And this is less than 0°C, so the answer is

20°F is colder than 0°C.

A certain siren radiates sound uniformly in all directions. At a distance of 17 m from the siren, the intensity level is 49 db.
AveGali [126]

Answer:

The power is  P =  2.88*10^{-4 } \ W

Explanation:

From the question we are told that

   The distance from the siren  is  d =  17 \ m

  The intensity level is  \beta  =  49\ dB

   The threshold of hearing is   I_0 = 1.0 *10^{-12} \ W/m^2

Generally the intensity level is mathematically represented as

      \beta  =  10dB * log [\frac{I}{I_o} ]

Where I is the intensity at which the siren radiates the sound

substituting values  

       49  =  10 * log [\frac{I}{1.0 *10^{-12}} ]

=>    I  =  7.94*10^{-8} W/m^2

Now the amount of power the siren put out is mathematically evaluated as

      P= IA

Where A is the area  of the siren which is taken as a sphere  and it  is mathematically evaluated as

       A =  4 \pi d^2

So  

     P =  I  * 4 \pi d^2

substituting values

    P =  7.94 *10^{-8}  * 4  * 3.142 * (17)^2

   P =  2.88*10^{-4 } \ W
