If the object with 10x stamped on the casing is aligned, the specimen's total magnification is 100x.

We all understand that 10X refers to the objective lens's effective magnification, which is ten times life size. When paired with a 10X ocular lens in a compound, this results in a final magnification of 100X. (10 X 10).

The sum of the magnifications from the two lens systems is the overall magnification. As a result, the 10X objective and 10X ocular lenses on the microscope would magnify the object by 10 x 10 or 100 times.

Explanation:

Adding bulbs into a series will make them dimmer because the current is decreased, adding bulbs to a parallel will not affect the brightness because the current through each individual bulb remains the same.

Therefore, Option (C) is correct.

A series circuit is one where the same current flows through all the components in the circuit. The current has only one path in series circuits. A parallel circuit is one where the electric current has multiple paths to flow through. The components of the parallel circuits will have the same voltage across all ends.

When we connect bulbs in the circuit where all are connected in series then the net resistance of the circuit will increase and the voltage across each bulb will decrease.

Since voltage decreases across each bulb then the current across each bulb will decrease and the bulb gets dimmer because the current is reduced.

When we connect bulbs in parallel the voltage and current across each bulb will remain the same and then adding bulbs to a parallel will not affect the brightness.

Answer:What' the question?

Explanation:

Answer:

Explanation:

Your answer is correct

In thermodynamics, heat and work are two ways in which energy can be transferred into or out of a system. The sign convention for heat and work is crucial in thermodynamics calculations.

When supplied to the system, heat is represented by the letter Q, which has a positive sign, and when released, a negative sign.

W stands for work, and it has a positive sign when the system performs work on the environment, and a negative sign when the environment performs work on the system.

Expansion work is the effort put forth by a system when it expands under a continuous external pressure.

A system's work when it grows is beneficial because energy is transmitted from the system to the surrounds and the system is working on its surroundings.

Contrarily, when the system is compressed, the environment works on it and energy is transferred from the environment to the system.

Entropy is the measure of how much useful energy is left in a system according to the Second Law of Thermodynamics.

Entropy is a measure of the amount of energy that is unavailable for use, and it increases as energy is used for work and some of the energy is lost as heat.

Entropy is an important concept in thermodynamics, as it is directly related to the efficiency of energy transfer or conversion processes. It is a measure of the amount of energy that is lost or wasted during a process, and it increases when energy is transferred from a hotter body to a cooler body.

The higher the entropy of a system, the lower the efficiency of any conversion of energy from one form to another. Therefore, it is important to understand entropy in order to design efficient energy-conversion systems.

Explanation:

To measure the speed of the wave on the string, the wavelength, and frequency are required. So by calculating the wavelength, the speed can be calculated.

The distance between two adjacent crests can be used to calculate a transverse wave's wavelength. The distance between two adjacent compressions can be used to calculate the wavelength of a longitudinal wave.

The wave speed can be determined using this equation if the wavelength and frequency are known. The quantity of waves that move in a wave's frequency is measured in waves per second.

Speed = Wavelength x Frequency).

Therefore, the wavelength and frequency of the wave on the string must be determined in order to calculate its speed. Consequently, the speed can be estimated by determining the wavelength.

Explanation:

The altitude of the satellite is 883.89 km

Generally, The Rayleigh criterion for resolution states that the minimum angle, θ, between two point sources that can be resolved is given by:

θ = 1.22 * λ / D

where

λ is the wavelength of light and

D is the diameter of the lens.

The minimum distance, d, between two point sources that can be resolved is given by:

d = θ * L

where

L is the distance from the lens to the image.

Given the green lights have a wavelength of 508 nm, we can convert it to meters:

λ = 508 * 10^-9 m

Given the diameter of the lens is 49.8 cm, we can convert it to meters:

D = 49.8 cm * (1 m / 100 cm)

= 0.498 m

Using the Rayleigh criterion, we can find the minimum resolvable angle:

θ = 1.22 * λ / D

= 1.22 * 508 * 10^-9 / 0.498

= 1.24449799*10^{-6} radians

We know the lights on the satellite are spaced 1.1 m apart, so:

d = 1.1 m

Solving for the distance from the lens to the image, L:

L = d / θ

= 1.1 m / 1.24449799*10^{-6} radians

=883890.53 m

Finally, converting the distance to kilometers:

L = 883890.53 m * (1 km / 1000 m)

= 883.89 km

Explanation:

The complete question is

A dog runs 300 m North and sees the dog catcher and runs 120 m south Whats the dogs displacement.

A jogger runs north for 3.0 miles. If this took 2.0 hours, what is the jogger’s average velocity in miles per hour?

The same jogger runs 3.0 miles on the track, starting and finishing his run after completing exactly 12 laps around the track. What is his average velocity?

1. Displacement is how far the dog moves from the original starting point.

If the dog runs 300 m north, and then 120 m south, then the displacement from the starting point will be

displacement = 300 - 120 = 180 m

2. Displacement of the jogger = 3 miles

Time taken by the jogger = 2 hours

velocity of the jogger = ?

Velocity is = displacement/time

velocity = 3/2 = 1.5 miles/hour

3. velocity = displacement/time

if the jogger completes exactly 12 laps around the track, then the jogger will return to the starting point. This means that the jogger's displacement from the starting point is 0 miles

A body starts from rest and travels for t seconds with uniform acceleration of 2m/s². If the displacement made by it is 16m the time of travel t will be 4 seconds.

If an object is traveling in a straight line path and its velocity increases or decreases by the equal amounts in equal intervals of time, then the acceleration of the object will be said to be uniform.

The time can be calculated through 2nd equation of motion.

s = ut + ½ at²

Given,

s = 16m      

a = 2m/s²

u = 0 (since the body starts from rest)

So,

16 = (0)t + 1/2(2) (t)²

After solving it,

16 = t²

t = 4

The value to be computed is:

\(a\cdot b\times c\)

Compute the value of (b × c) as follows:

\(b\times c=\left|\begin{array}{ccc}i&j&k\\1&0&2\\0&1&-1\end{array}\right|\)

As the temperature increases, the volume of the material also increases. This is known as thermal expansion. It can also be explained as the fractional change in the length or volume per unit change in the temperature.

The relation between alpha, beta, and gamma is given in the form of a ratio and the ratio is 1:2:3 and can be expressed as:

alpha=fracbeta2=fracgamma3

Following is the relation between the three:

L = L (1 + α.ΔT)

Where, α is the coefficient of linear expansion  

A = A (1 + β.ΔT)

Where, β is the coefficient of aerial expansion

V = V (1 + γ.ΔT)

Where, γ is the coefficient of cubical expansion  

V = V + γV.ΔT

V = V (1 + γ.ΔT)  

L3 = L3 (1 + α.ΔT)3

L3 = L3 (1 + 3α.ΔT + 3α2.ΔT2 + α3.ΔT3)

L3 = L3 (1 + 3α.ΔT)

Alpha, beta, and gamma are related to one another in the form of a ratio, and that ratio is 1:2:3, and yes they are universal constants.

A substance's volume expands while its mass stays constant. Heating is typically the cause of expansion. When a substance is heated, the molecular bonds separating its particles weaken, the particles move more quickly, and the substance expands as a result.

Determine the relation as shown below,

L = L (1 + α × Δ T)

here, α is the coefficient of linear expansion  

A = A (1 + β × Δ T)

here, β is the coefficient of aerial expansion

V = V (1 + γ × Δ T)

here, γ is the coefficient of cubical expansion  

V = V + γ × V × Δ T

V = V (1 + γ × ΔT)  

L3 = L3 (1 + α × Δ T)3
