The resolution limit of an optical system depends on both (a) The wavelength of light and (b) The diameter of the aperture. These two factors determine the diffraction limit, which is the smallest distance between two points that can be resolved by the optical system.

The wavelength of light affects the resolution limit because shorter wavelengths are able to resolve smaller details than longer wavelengths. The diameter of the aperture also affects the resolution limit because a larger aperture allows for more light to enter the system, which can improve the resolution.

The distance to the object being viewed (option c) and the distance from the aperture to the light detectors (option d) do not affect the resolution limit of an optical system. These factors may affect the overall image quality, but they do not determine the smallest distance between two points that can be resolved by the system.

The electrical energy consumed by the dryer in 1.5 minutes is 237,600 joules.

Electrical energy is a form of energy that results from the movement of electric charge. It is the energy that is transferred or converted when electric current flows through a conductor or a circuit.

Electricity is generated at power plants using various sources of energy such as fossil fuels, nuclear power, or renewable energy sources like wind, solar, or hydroelectric power. This electrical energy is then transmitted through high-voltage power lines and distributed to homes.

First we should calculate the power:

power = voltage x current

power = 220 V x 12 A = 2640 W

Now we can calculate the electrical energy consumed by the dryer in 1.5 minutes:

Electrical energy = power x time

= 2640 W x 90 s

= 237,600 joules (J)

Answer:

118,000 J

Explanation:

The law of conservation of energy states that the total energy in a system remains constant, it can be transformed from one form to another, but the total energy remains the same.

Given that the total energy of the object is 210,000 J, and its potential energy at a certain point along the track is 92,000 J, we can use the law of conservation of energy to find the kinetic energy of the object at that point.

The total energy of the object is equal to the sum of its kinetic energy (KE) and its potential energy (PE):

E_total = KE + PE

Substituting the given values:

210,000 J = KE + 92,000 J

Solving for KE:

KE = 210,000 J - 92,000 J = 118,000 J

So, the object has a kinetic energy of 118,000 J at the same point where its potential energy is 92,000 J.

This follows the law of conservation of energy because the total energy of the object remains constant, and the change in potential energy is equal to the change in kinetic energy.

Explanation:

a) The fisherman sees the cage at a different location than where it actually is because of the refraction of light in water. When light travels from air into water, its speed decreases, causing the light to bend or refract. This means that the light entering the fisherman's eyes is coming from a slightly different direction than the actual position of the cage, making it appear as if the cage is in a different location.

b) To calculate the angle of the refracted ray in the camera lens, we can use Snell's law, which states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two materials.

Using this formula, we can calculate the angle of refraction in the lens:

sin(θ2) / sin(θ1) = n2 / n1

where n1 is the refractive index of water (1.40), n2 is the refractive index of the lens (1.49), and θ1 and θ2 are the angles of incidence and refraction, respectively.

Solving for θ2, we find:

θ2 = sin^-1(sin(θ1) * n1 / n2) = sin^-1(sin(37.2°) * 1.40 / 1.49) = 35.0°.

So, the refracted ray in the camera lens will be at an angle of 35.0° to the normal.

From the information provided,  each christmas tree bulb has a resistance of approximately 257.4 Ω.

To determine the resistance of each bulb, we first need to find the total resistance of the circuit. We can use Ohm's law to do this:

V = IR

where V is the voltage (120 V), I is the current, and R is the total resistance. Since the lights are connected in series, the current is the same through each bulb. We can use the power of each bulb (7 W) and the voltage to find the current:

P = IV

I = P/V = 7 W / 120 V = 0.0583 A

Now we can use Ohm's law to find the total resistance:

R = V/I = 120 V / 0.0583 A = 2059.5 Ω

Since there are eight bulbs, each bulb has the same resistance. We can find the resistance of each bulb by dividing the total resistance by the number of bulbs:

R_each = R_total / number of bulbs = 2059.5 Ω / 8 = 257.4 Ω

-4.97t^2 + 38.5t + 5.6 = 0

We can use the quadratic formula to solve for t:

t = (-b ± √(b^2 - 4ac)) / 2a

where

a = -4.97,

b = 38.5, and

When producing modest swings, the amplitude frequently has no impact at all on the pendulum's period. There is a tiny but insignificant rise in the period when the pendulum's amplitude is greater.

The distance to travel increases as the amplitude rises, but when the restoring force rises as well, the acceleration rises correspondingly.

This implies that the mass can move faster and cover a bigger distance. Since these qualities cancel one another, amplitude has no bearing on period.

[tex]2\; {\rm \Omega}[/tex].

Explanation:

The lower case "[tex]r = 1\; {\rm \Omega}[/tex]" in the circuit diagram indicates that the internal resistance of this [tex]12\; {\rm V}[/tex]-battery is [tex]1\; {\rm \Omega}[/tex].

In practice, the rated [tex]12\; {\rm V}[/tex] voltage drop across this battery is split across not just the resistors in the external circuit, but also across the internal resistance of the battery.

The voltameter in this circuit measures the voltage drop across the [tex]3\; {\rm \Omega}[/tex] resistor and the unknown resistor [tex]R[/tex]. The voltage drop across the internal resistance and the other resistor (a total of [tex]1\; {\rm \Omega} + 4\; {\rm \Omega} = 5\; {\rm \Omega}[/tex]) would be [tex]12\; {\rm V} - 6\; {\rm V} = 6\; {\rm V}[/tex].

Divide the voltage drop by the resistance to find the current:

[tex]\begin{aligned}I &= \frac{V}{R} \\ &= \frac{6\; {\rm V}}{5\; {\rm \Omega}} = 1.2\; {\rm A}\end{aligned}[/tex].

Since this circuit is serial, current would be the same everywhere in the circuit. Given that voltage drop across the [tex]3\; {\rm \Omega}[/tex] resistor and the unknown resistor is [tex]6\; {\rm V}[/tex], the resistance of that part of the circuit would be:

[tex]\begin{aligned}\frac{6\; {\rm V}}{1.2\; {\rm A}} = 5\; {\rm \Omega}\end{aligned}[/tex].

Subtract the [tex]3\; {\rm \Omega}[/tex] from the resistance to find the value of [tex]R[/tex]:

[tex]R = (5\; {\rm \Omega} - 3\; {\rm \Omega}) = 2\; {\rm \Omega}[/tex].

The required acceleration of the car compared to g is 0.36 times the value of g.

The distance covered = 0.25 miles = 0.25× 1609 m/ 1 mile = 402.336 m

Initial velocity u = 0

Let us find the acceleration of the car using the equation of motion.

v² - u² = 2 a s

where,

v is final velocity

u is initial velocity

a is acceleration

s is distance

Entering values in the above equation, we have,

a = 3.57 m/s²

Let us compare it with the value of 'g',
