This object is located 13.0 cm to the left of the lens and the image forms at 20.8 cm to the right of the lens.

What is the focal length of the lens?

Answers

Answer:

0.125 cm

Explanation:

1/f = 1/d¡ + 1/d。

Find the focal point

(13.0^-1 + 20.8^-1) = 0.125 m

Focal point = 0.125 m  

The object placed in front of mirror forms an image on the opposite side of the mirror. The focal length of the lens is 0.125 m.

What is focal length?

Focal length is the distance between the lens and the image sensor when the object is in focus.

The focal length can be find out by using lens maker formula.

1/f = 1/d¡ + 1/d。

1 / 13.0 + 1 / 20.8

f = 0.125 m

Thus, the focal length of the lens is 0.125 m.

What is the gamma factor for an object moving at 0.5c?
A. 0.866
B. 0.707
C. 1.15
D. 1.41​

Answers

Answer:1.15

Explanation:

Answer:

C. 1.15

Explanation:

We can calculate the gamma factor for an object moving at 0.5c, using the formula:  

γ = 1/√(1 - v^2/c^2)

--------

where v is the velocity of the object and c is the speed of light.

Substituting v = 0.5c, we get:

γ = 1/√(1 - 0.5^2) = 1/√(1 - 0.25) = 1/√0.75 ≈ 1.155

--------

Therefore, the gamma factor for an object moving at 0.5c is approximately 1.155.

Answers

Answer:

At infinity the image is formed

When a lens produces light rays that are parallel, the image is: C. non-existent.

A ray diagram can be defined as the graphical representation of the possible paths light takes from one point (source) to another.

Hence, a ray diagram is a graphical representation of how light interacts with a boundary, so as to help us view a point on the image of an object.

Basically, the characteristics of an image produced from a lens or mirror can be determined by drawing a ray diagram of the possible paths taken by light.

On a ray diagram, an image produced from a lens is non-existent when the lens produces light rays that are parallel because the refracted rays of light neither diverge nor converge.

In conclusion, an image cannot be formed (non-existent) when a lens produces light rays that are parallel, due to refraction.

What can Lisa do to increase the strength of the electromagnet? She can use a nail with weaker magnetic properties. She can change the direction of the nail. She can increase the number of wire loops. She can reduce the current in the wire.

Answers

Answer:She can increase the number of wire loops

Explanation: When the number of loops of wire ( usually around the iron ) increases, the strength of the electromagnet is increased.

According to the equation

B=μ₀ N I

Where

μ₀ = permeability of the core

N= Number of turns of the coil

I= Current flowing through the coil

From the equation above , we can see that The strength of an electromagnet depends the amount of current, no of turns of coil and the permeability  core of coil. we can now say that Increasing the  number of wire loops  increases the strength of electromagnet.

Therefore, Lisa should increase the number of wire loops to increase the strength of the electromagnet

7. Can the speed of a particle be negative? Can the
velocity of a particle be negative? Give arguments to
support your answers.

Answers

Answer:

Suppose at time t1 = zero and v1 = 50 MPH

                    time t2 = 10 sec and v2 = 10 MPH

Change in speed   =  (v2 - v1) / (t2 - t1) = (10 - 50) MPH / (10 - 0) sec

Change in speed = -40 MPH / 10 sec = - 4 MPH / sec

If you specify the velocity as always East then

change in velocity = - 4 MPH East

Had the particle finished by moving in the Westerly direction  then

Change in velocity = (-10 - 50) MPH / 10 sec = -60 / 10 MPH = -60 MPH East

Where West was the positive direction

Initially v1 was 50 East and v2 was -10 East with a difference of 60 MPH

A pulley lifts a 72-N load with a force of 24-N. The input distance is 2m and the output distance is 0.5m. What is the efficiency of the pulley system

Answers

Answer:

Explanation:

Work done on the lever ( input energy ) = force applied x input distance

= 24 N x 2m = 48 J

Work done by the lever ( output energy ) = load x output distance

= 72 N x 0.5m = 36 J

efficiency = output energy / input energy

= 36 J  / 48 J

= 3 / 4 = .75

In percentage terms efficiency = 75 % .

We know that

m1 = 7 kg. Vi1 = +5.0 m/s (east is +) Vf1 = -2.0 m/s

m2 = 3.0 kg. Vi2 = -6.0 m/s (west is -) Vf2 = ?

or

(7)(5) + (3)(-6) = (7)(-2) + 3Vf2

Solving for Vf2, we get

A fisherman sees 7 wave crests go by in 10.0 s. The crests are 2.43 m apart. Find the period of the wave. (Unit = s)​

Answers

Velocity of the wave is 1.7 m/s

Explanation:

As we know that the frequency of the wave is defined as the number of waves crossing a fixed point per second

So here we will have

Also we know that the distance between two consecutive crest or two consecutive trough is known as wavelength

So here the wavelength of the wave is given as

now we have

The wave period will be 1.42 s.

What is wave period?

The time interval, expressed in seconds, separating two waves as they pass throughout a stationary point has been known as the wave period.

What is wave?

A pulse seems to be a single disturbance, whereas a wave would be a persistent, repeated interruption of a medium.

Calculation of wave period

The frequency = 7 / 10 = 0.7 Hz

Wave period can be calculated by the formula:

Wave period = 1 / frequency

Put the value of frequency in above equation.

Wave period = 1 / 0.7

Wave period = 1.42 s

Therefore, the wave period will be 1.42 s
