Answer:

η₁ = 2.6

Explanation:

Here, we will use snell's law to calculate the refractive of the substance:

\(\frac{\eta_2}{\eta_1} = \frac{Sin\theta_1}{Sin\theta_2}\)

where,

η₁ = refractive index of first substance = ?

η₂ = refractive index of second substance = 1.5

θ₁ = angle of incidence = 30°

θ₂ = angle of refraction = 60°

Therefore,

\(\frac{1.5}{\eta_1} = \frac{Sin\ 30^0}{Sin\ 60^0}\)

η₁ = 2.6

The wall is positively charged, whereas it is negatively charged. If a woollen fabric is not used to massage it, it will not do so. When the sand was drawn inside the balloon, the same thing occurred.

Positive charges pull away from negative charges. The balloon will attract the wool fabric if it is not touched since it contains an equal balance of negative and positive charges. Both balloons will reject one another when they are brushed with the wool cloth because they both receive negative charges.

Positive and negative particles make up the water. Because positive and negative ions are attracted to one another, when you bring the balloon near the water, the positively charged water molecules will pull the water in the direction of the negatively charged balloon.

Answer: 490.5 N

Explanation:

In this case, the only two forces acting on the mass are the person's strength (i.e. the force in question) and the weight of the mass.

The sum of the forces is equal to 0. This means that Force (person) = Force (weight).

Fp = Fw = m * gravity

Fp = 50 kg * 9.81 m/s^2

Fp = 490.5 (kg*m/s^2)

Fp = 490.5 N

Answer:

96 m

Explanation:

Given,

Initial velocity ( u ) = 4 m/s

Final velocity ( v ) = 20 m/s

Time ( t ) = 8 s

Let Acceleration be " a ".

Formula : -

a = ( v - u ) / t

a = ( 20 - 4 ) / 8

= 16 / 8

a = 2 m/s²

Let displacement be " s ".

Formula : -

s = ut + at² / 2

s = ( 4 ) ( 8 ) + ( 2 ) ( 8² ) / 2

= 32 + ( 2 ) ( 64 ) / 2

= 32 + ( 2 ) ( 32 )

= 32 + 64

s = 96 m

Therefore, it travels 96 m in time 8 s.

The relationship between molar mass and delta t (Δt) is derived from the colligative properties of solutions. Colligative properties are those properties that depend on the number of solute particles in a given volume of solution, regardless of the type of solute particles.

One of the colligative properties is the freezing point depression, which is the difference between the freezing point of a pure solvent and the freezing point of a solution containing a solute. The freezing point depression is directly proportional to the molality (moles of solute per kilogram of solvent) of the solution, and inversely proportional to the molar mass of the solute. This can be mathematically expressed as Δt = Kf * m * (1/M), where Δt is the freezing point depression, Kf is the freezing point depression constant, m is the molality of the solution, and M is the molar mass of the solute. Therefore, as the molar mass of the solute increases, the freezing point depression decreases, and vice versa. This relationship can be useful in determining the molar mass of an unknown solute in a solution.

The compression in the spring will be 4.9m

What is spring force?

The force needed to compress or extend a spring attached to an object is known as the spring force. A spring exerts an equal and opposite force on a body when the object exerts a force on it. It always acts to bring mass back to its equilibrium. Spring force exerted by the spring on the body is given by = where k is the spring constant of the spring x is the compression or extension caused in the spring. To find the x we can use this formula.

Now, according to the question we have

Spring constant=2000N/m

Mass attached to the spring=1000Kg

On substituting the values in the above formula, we get the compression as

F=kx

mg=kx

1000×9.8=2000×x

x=4.9m

Therefore, the compression in the spring is 4.9m

A. Acceleration during launch = 4000 m/s²

B. Distance that the froghopper moves while its legs are pushing = 0.002 m

Kinematics is sometimes regarded as a subfield of mathematics and is sometimes referred to as the geometry of motion. But in physics, it serves as the basis for classical mechanics. Without considering the forces that propel an item, kinematics studies how an object moves. It gives a description of the spatial positions of bodies or systems of material particles as well as the velocities and rates of change of those velocities.

t = 0.001 s

u = 4 m/s

PART A :

a = Δv / t

a = \(\frac{4m/s}{0.001s}\)

a = 4000 m/s²

Therefore, Acceleration during launch = 4000 m/s²

PART B :

S = ut +  \(\frac{1}{2}\)at²

S = 0(0.001s) + \(\frac{1}{2}\)  x 4000 m/s² (0.001)²

S = 0.002 m

Therefore, the Distance that the froghopper moves while its legs are pushing = 0.002 m

We can calculate the focal length of the lens as follows:1/f = 1/d₀ - 1/d₁ = 1/2940 + 1/215910 = 0.00052So,f = 1/0.00052 = 1923.08 mm . Therefore, the focal length of the projection lens is approximately 1923.08 mm.

In order to find out the focal length of the projection lens for the given LCD projector, we can use the thin lens equation which is given as follows:1/f = 1/d₀ + 1/d₁ where f = focal length of the projection lensd₀ = distance of the object from the lensd₁ = distance of the image from the lens .

Given data: Object height, h₀ = 24.2 mm Image height, h₁ = 1.78 m = 1780 mm .

Distance of the object from the lens, d₀ = 2.94 m = 2940 mm . Now, we need to calculate the distance of the image from the lens, d₁. For that, we can use the magnification formula which is given as:m = - h₁/h₀ = d₁/d₀So, we can rearrange the above formula as:d₁ = - (h₁/h₀) × d₀ = - (1780/24.2) × 2940 = - 215910 mm .

We can see that the value of d₁ comes out to be negative which means that the image is formed on the opposite side of the lens. This shows that the lens is a diverging lens. Therefore, we can calculate the focal length of the lens as follows:1/f = 1/d₀ - 1/d₁ = 1/2940 + 1/215910 = 0.00052So,f = 1/0.00052 = 1923.08 mm . Therefore, the focal length of the projection lens is approximately 1923.08 mm.

Explanation:

In these semicircular sections the skaters slide from one side to the other, in the downward path their kinetic energy increases and their potential energy decreases; When it leaves the ramp and is in the air, the kinetic energy decreases rapidly, up to the point of maximum height where the kinetic energy is zero.

Consequently, the kinetic energy increases on the descent, being maximum at the lowest point of the trajectory.

The designed Ka-Band receiving earth station is made of an antenna of 2.5 meters in diameter.

The Ka-Band (26–40 GHz) receiving earth station is designed as follows:

First, consider the carrier to noise ratio equation:

C/N = EIRP – Losses – Atten + G/T – NTo obtain the total air C/N ratio, use the following formula:

C/N = EIRP – Losses + G/T – NTEIRP (Effective Isotropic Radiated Power) is calculated as follows:

EIRP = Pt + Gtx – Ltx + Ga - La + Gr - LrPt

        = 2 W (the 2 dB output back off is already accounted for)Gtx and Ltx are gain and loss of the transmitting antenna, respectively.

Ga and La are gain and loss of the waveguide, respectively.Gr and Lr are gain and loss of the receiving antenna, respectively.

G/T is calculated as follows:

G/T = G – TaG and Ta are the gain and noise temperature of the antenna, respectively.

For Ka-band, Ta = 30 K, Tn = 65 K, and Bn = 37 MHz.

Using the Boltzmann equation, N is calculated as:

N = kTBnWhere k = Boltzmann's constant and Bn is the bandwidth of the noise signal.

For Ka-band, losses can be calculated as follows:

Losses = Atten + Other lossesAtten is the clear air atmospheric attenuation, which is 0.7 dB for Ka-band.

The diameter of the receiving antenna, considering the aperture efficiency of 75%, is determined using the following formula:

D = 1.2 * λ / θWhere θ = 1.22 * λ / Daperture (in radians) and Daperture = D * Aperture efficiency.λ = c / f (where c is the speed of light and f is the frequency in Hz).

Therefore, the designed Ka-Band receiving earth station is made of an antenna of 2.5 meters in diameter. The C/N ratio can be calculated using the above equations.
