The following table shows the duration of a year on some unknown planets of equal mass. Duration of Year Planet Duration of Year

Y 224 days Z 320 days Which of the following best explains which planet is closer to the sun? Planet Y, because gravity is directly proportional to square of distance Planet Z, because gravity is directly proportional to the square of distance Planet Z, because the sun exerts a greater gravitational force on it than on planet Y Planet Y, because the sun exerts a greater gravitational force on it than on planet Z

Gravitational force between sun and planet is given by,

F=\frac{GMm}{r^{2}}

Thus, The force of gravitation is inversely proportional to the distance.

Kepler's law states that the square of period of planet is proportional to cube of semi major axis of its orbit.

The time period of planet is more when the gravitational force is less.

Thus, planet Y is closer to earth because sun exert greater gravitational force than planet Z.

The density of a material is constant and it is given by the ratio of the mass to the volume of the material

The mass of the liquid and the full bottle ae

The mass of the liquid is <u>450 g</u>

The mass of the filled bottle is <u>530 grams</u>

<u></u>

The reason the above values are correct are as follows:

The given parameters are;

Volume of the bottle, V = Half litre

Mass of the bottle, m_b = 80 g

The volume of liquid in the bottle when filled, V = 500 cm³

The density of the olive oil with which the bottle is filled, ρ = 0.9 g/cm³

a. Required:

To calculate the mass of oil in the bottle

Solution:

The volume of oil in the bottle when the bottle is filled, V = 500 cm³

Density, \ \rho = \dfrac{Mass}{Volume}  = \dfrac{m}{V}

The mass of the liquid, m = ρ × V

∴ m = 0.9 g/cm³ × 500 cm³ = 450 g

The mass of the liquid, m = <u>450 g</u>

<u></u>

b. The mass of the oil in the bottle, m = grams

The mass of the full bottle, m_{filled} = m + m_b

∴ m_{filled} = 450 g + 80 g = 530 g

The mass of the full bottle, m_{filled} = <u>530 grams</u>

What’s the mathematical relation between them
Gekata [30.6K]

Explanation:

there is no relationship between small mass and the bigger mass, but it can be related with the acceleration. Since Force is constant, acceleration is inversely proportional to the mass. Greater the mass, lesser is the acceleration and vise versa

What is the state of y when y = k/x, x is halved.
tangare [24]

Answer:

y becomes doubled.

Explanation:

If;

       y  = \frac{k}{x}  

what is the state of y when x is halved;

  the given expression is an inverse relationship. When y increases, x is supposed to decrease and vice versa.

 

 if x is halved; x  = \frac{x}{2}

           \frac{k}{\frac{x}{2} }   = \frac{2k}{x}  

Now compare :

      \frac{k}{x}  :  \frac{2k}{x}

we see that y becomes doubled

You are given two infinite, parallel wires each carrying current I. The wires are separated by a distance d, and the current in
Zarrin [17]

Answer:

a) The force between the two wires is attractive.

b) (F/L) = (μ₀I²)/(2πd)

Explanation:

a) According to Ampere's law, current in the same direction attract, while current in opposite directions repel. So, for this case of two wires carrying curremt in the same direction, the force between the wires is attractive.

b) The force of attraction between two current carrying wires carrying currents of magnitude I₁ and I₂ respectively, at some distance d, apart is given as

F = (μ₀ I₁ I₂ L)/(2πd)

(F/L) = (μ₀ I₁ I₂)/(2πd)

I₁ = I₂ = I

(F/L) = (μ₀I²)/(2πd)

Hope this Helps!!

The instrument includes a light source, which is passed through a Choose... , which isolates a single wavelength to pass through
zloy xaker [14]

Answer:

Following are the response to the given question:

Explanation:

It's being used to measure the amount of light absorbed after traveling through a test tube (the amount of solar radiation received). For several quantitative estimations, this technique is widely employed. Spectrometer and Spectrometer were two devices that are used together to light intensity and light intensity.

It creates and diffuses phosphorescent light into the selected frequency, while the Spectrometer measures the strength of attenuation by the sample solution.

Diffraction beams or prisms are being used to convert polychromatic illumination into monochrome light.

Afterward, the sunlight has a certain hue. Once it reaches the specimen cuvette, it begins absorption. It falls on a sensor that transforms its intensity into such an electronic current.

Here are some ways to fill in such gaps:

In order to reach the specimen cuvette, the light from the light source must be routed via an aperture in order to be isolated by either a diffraction pattern. Light travels to the detector, which detects its intensity.
