light of wavelength λ = 630 nm and intensity i0 = 250 w/m2 passes through a slit of width w = 3.6 μm before hitting a screen l = 1.7 meters away
Use the small angle approximation to write an equation for the phase difference, β, between rays that pass through the very top and very bottom of the slit when the rays hit a point y - 79 mm above the central maximunm.

Answers

Answer 1

Light of wavelength λ = 630 nm and intensity i0 = 250 W/m2 passes through a slit of width w = 3.6 μm before hitting a screen l = 1.7 meters away. The diffraction pattern of the light is observed on the screen.

When light passes through a slit, it diffracts, causing the light to spread out. The diffraction pattern of the light is observed on the screen. The pattern consists of a bright central maximum surrounded by a series of alternating bright and dark fringes. The distance between adjacent bright fringes is given by:

Dλ/w = (l/y)m

where D is the distance between the slit and the screen, λ is the wavelength of the light, w is the width of the slit, l is the distance from the slit to the screen, y is the distance from the center of the pattern to a bright fringe, and m is an integer representing the order of the bright fringe.

Using the given values, we can calculate the distance between adjacent bright fringes as:

y = (Dλ/w)(m*l)

For m = 1, the distance between adjacent bright fringes is y ≈ 0.0029 m.

If your maximum braking force is 7.0 N, will you stop before you hit the oil spill? What is your braking distance?

Answers

You will not stop before you hit the spill.

Your braking distance is 10.8 m.

What is the minimum distance you can travel?

The minimum distance you can travel at the maximum braking force is calculated as follows;

Apply the principle of work energy theorem as follows;

K.E = W

¹/₂mv² = Fd

where;

m is the mass of the Kartv is the speed of the KartF is the maximum braking forced is the minimum distance travelled

What are the factors required for the choice of electric propulsion systems for EVs and HEVs?

Answers

When it comes to choosing the right electric propulsion system for electric vehicles (EVs) and hybrid electric vehicles (HEVs), there are several factors to consider. These include power needs, cost, efficiency, environmental impact, and safety.

Power needs are important to consider as the right system will be able to provide enough power for the vehicle’s needs without overpowering it. Cost is also an important factor when selecting a propulsion system as some systems can be expensive.

Efficiency is also key to consider as some systems can be more efficient than others. Environmental impact is also important as some propulsion systems are more efficient and have lower emissions than others. Finally, safety is an important consideration, as some systems may be safer than others.

By considering all of these factors when selecting an electric propulsion system for an EV or HEV, vehicle owners can ensure they are making the best choice for their needs.

lydia picks up oranges each of which is 1kg from a basket on the ground and puts them on a table that is 1.5 meter high. how much work is she doing on each orange

Answers

Explanationnswer:



Answer:find out ;/

Explanation:

To calculate the amount of work Lydia is doing on each orange, you need to use the formula for work, which is Work = Force x Distance x Cos(theta). In this case, the force is the weight of the orange (1 kg), the distance is the height of the table (1.5 meters), and theta is the angle between the force and the distance (which is assumed to be 90 degrees, since she is lifting the orange straight up).

So the work done on each orange is 1 kg x 1.5 meters x cos(90) = 1.5 Joules.

The speed of the two-cart system’s center of mass during the collision in Trial 1: Does not change, and in Trial 2: Decreases.

In Trial 1 of the experiment, the carts collide elastically and the speed of the two-cart system's center of mass does not change during the collision. In Trial 2, the carts stick together and the collision is inelastic. Some of the kinetic energy is converted into internal energy, resulting in a decrease in kinetic energy and the speed of the center of mass. In conclusion, the speed of the center of mass does not change during the collision in Trial 1, but, decreases in Trial 2 as a result of a decrease in the kinetic energy.

Answers

An inductor and a resistor are connected in a simple series circuit. If the inductance increases, the current in the circuit decreases. The correct answer is b.

An inductor is a passive component that stores energy in a magnetic field when electric current flows through it. In a series circuit, the current flows through both the inductor and the resistor. When the inductance of the inductor increases, the opposition to the current flowing through it also increases, known as inductive reactance. This results in a decrease in the current flowing through the circuit, as more energy is being stored in the magnetic field of the inductor and less is available to flow through the resistor.

How do astronomers find asteroids heading toward Earth?

Answers

Astronomers use a variety of techniques to find asteroids that may be on a collision course with Earth. Some of them are by using optical telescopes and infrared telescopes, and radio telescopes. Once an asteroid is detected, astronomers use its position and velocity data to calculate its orbit and determine if it poses a threat to Earth.

Optical telescopes are equipped with cameras that can take images of a large area of the sky at once. The images are then compared over time to identify asteroids that are moving in relation to the stars.

Infrared telescopes are useful for finding asteroids that are in the inner solar system, where they are closer to the sun and therefore warmer. This is particularly useful for finding asteroids that are difficult to detect using traditional optical telescopes, as many asteroids are dark and therefore do not reflect much light.

Radio telescopes involve bouncing radar waves off asteroids and measuring the time it takes for the waves to return. By analyzing the radar data, astronomers can determine the asteroid's distance and speed, as well as its size and shape.
