The rotational speeds of four generators are listed in RPM (revolutions per minute). Arrange the generators in order based on th

The equation that connects the various variables is:

distance between lines * sin(angle of diffraction) = order of band * wavelength

dsin(∅) = nλ

To calculate the spacing between the lines, we can use the information that there are 425 lines per mm, and since 1 mm is equivalent to 0.001 m, we find

d = 0.001 / 425 = 2.35 x 10⁻⁶ m
The wavelength is λ = 475 x 10⁻⁹ m

By substituting these values,

2.35 x 10⁻⁶ * sin(∅) = 1 * 475 x 10⁻⁹
∅ = 11.7°


Thus, the angle for the first-order bright band, or maxima, is 11.7°

Answer:

The books are displaced to the left due to inertia and ultimately halt when impacted by the car door.

Explanation:

The movement of the books can be understood through Newton's first two laws:

- The first law (Law of Inertia): an object will remain at rest or continue moving in a straight line unless an unbalanced force acts upon it.

- The second law: if unbalanced forces act on an object, it experiences an acceleration that can be described by the formula

where F is the object's net force, m its mass, and a its acceleration.

Now let's relate this to the scenario:

- When Argelia makes a sharp right turn, the books, which are not secured in the car, maintain their straight-line motion due to inertia so they appear to move left as the car shifts right.

- Upon contacting the car door, the books cease moving due to the second law: the door exerts an unbalanced force, causing the books to decelerate and ultimately come to rest.

Answer:

The wire length is 32 inches.

Explanation:

According to the question,

The pipe's length = 60 inches

The pipe's circumference = 4 inches

Now,

The wire wraps around the pipe for 8 complete turns.

Now, with 2πr = 4, we find that

r = 2/π

Thus,

The radius, r = 2/π

The wire's length can be calculated as,

Length = Number of turns x Circumference of the pipe

So, length of wire = 8 x 4 = 32 inches.

Consequently, the wire length is 32 inches.

Response:

I am completely unsure

Clarification:

Answer: The frequency is 1714.3 Hz

Explanation: The calculation is derived from the Doppler effect formula.

Since the source is approaching the observer, the observer's velocity is considered positive.
