The values into the formula gives:

Magnification (m) = -di/0.108

Problem (1):

(a) To determine the location of the object, we can use the mirror equation:

1/f = 1/do + 1/di

Given:

Focal length (f) = 0.120 m

Image distance (di) = -0.360 m (negative sign indicates a virtual image)

Solving the equation, we can find the object distance (do):

1/0.120 = 1/do + 1/(-0.360)

Simplifying the equation gives:

1/do = 1/0.120 - 1/0.360

1/do = 3/0.360 - 1/0.360

1/do = 2/0.360

do = 0.360/2

do = 0.180 m

Therefore, the object is located 0.180 m in front of the mirror.

(b) The magnification can be calculated using the formula:

Magnification (m) = -di/do

Given:

Image distance (di) = -0.360 m

Object distance (do) = 0.180 m

Substituting the values into the formula gives:

Magnification (m) = -(-0.360)/0.180

Magnification (m) = 2

The magnification is 2, which means the image is twice the size of the object.

(c) The image is virtual since the image distance (di) is negative.

(d) The image is inverted because the magnification (m) is positive.

(e) The image is enlarged because the magnification (m) is greater than 1.

Problem (2):

To obtain the speed of light in the material, we can use Snell's law:

n1 * sin(θ1) = n2 * sin(θ2)

Given:

Angle of incidence (θ1) = 63.0 degrees

Angle of refraction (θ2) = 47.0 degrees

Speed of light in air (n1) = 1 (approximately)

Let's assume the speed of light in the material is represented by n2.

Using Snell's law, we have:

1 * sin(63.0) = n2 * sin(47.0)

Solving the equation for n2, we find:

n2 = sin(63.0) / sin(47.0)

Using a calculator, we can determine the value of n2.

Problem (3):

(a) To determine the location of the screen, we can use the lens formula:

1/f = 1/do + 1/di

Given:

Focal length (f) = 105 mm = 0.105 m

Object distance (do) = 108 mm = 0.108 m

Solving the lens formula for the image distance (di), we get:

1/0.105 = 1/0.108 + 1/di

Simplifying the equation gives:

1/di = 1/0.105 - 1/0.108

1/di = 108/105 - 105/108

1/di = (108108 - 105105)/(105108)

di = (105108)/(108108 - 105105)

Therefore, the screen should be located at a distance of di meters from the lens.

(b) To find the dimensions of the image, we can use the magnification formula:

Magnification (m) = -di/do

Given:

Image distance (di) = Calculated in part (a)

Object distance (do) = 108 mm = 0.108 m

Substituting the values into the formula gives:

Magnification (m) = -di/0.108

The magnification gives the ratio of the image size to the object size. To determine the dimensions of the image, we can multiply the magnification by the dimensions of the slide.

Image height = Magnification * Slide height

Image width = Magnification * Slide width

Given:

Slide height = 24.0 mm

Slide width = 36.0 mm

Magnification (m) = Calculated using the formula

Answer:

The starting position of the runner.

Explanation:

When you look at the graph, you can see that the first point on the graph is twenty on the y-axis.

The runner starts at twenty, and ends at thirty.

Therefore, the runner starts at twenty on the y-axis, so it's the starting position of the runner.

The y-intercept tell you about the starting position of the runner.

The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

When we look at the graph, we can see that the first point on the graph is twenty on the y-axis.

The runner starts at twenty and ends at thirty.

Earth is stuck in orbit around the sun, because of the Sun's gravitational pull. In this scenario, the string represents gravity, keeping the Earth attracted towards the sun.

Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day and good luck with your assignment :)

The student ties a string around a weight and swings the weight in a circle around her body. If the student represents the sun and the weight represents earth, the string will represent GRAVITY then.

In mechanics, gravity—also known as gravitation—is the constant force of attraction that pulls all things together. It has little impact on determining the intrinsic characteristics of common stuff because it is by far the weakest known force in nature.

In contrast, it governs the formations and evolution of stars, galaxies, and the entire cosmos by its extensive and ubiquitous action, which affects the trajectories of objects in the solar system and beyond the universe. All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass.

As the student represents the sun and the weight represents earth, the string will represent GRAVITY then. Hence, option (A) is correct.

The velocity of Sam just before hitting the ground is 294 m/s.

The above situation represents a case of motion in one dimension.

This type of motion is governed by the following three equations of motion,

v = u + at

v² - u² = 2as

S = ut + 1/2 at²

As in the given case, the acceleration and time have been given and the final velocity is to be calculated, therefore the 1st equation can be used,

v = u+ at

As Sam jumped from the plane, his initial velocity is zero.

So,

v = 0 + 9.8(30)

v = 294 m/s.

Thus, Sam's velocity just before hitting the ground is 294 m/s.

Explanation:

Answer: The change in momentum is +20 kg.m/s

Explanation:

To calculate the final velocity of object, we use the first equation of motion:

\(v=u+at\)

where,

v = final velocity

u = initial velocity = 0 m/s

a = acceleration = \(10m/s^2\)

t = time = 0.5 s

Putting values in above equation, we get:

\(v=0+(10\times 0.5)\\\\v=5m/s\)

Momentum is defined as the product of the mass and velocity of an object. It is given by the equation:

\(p=mv\)

where,

p = momentum

m = mass of object = 2 kg

Let the upward velocity be positive and the downward velocity be negative

When the object is dropped, the velocity is downward

v = -5m/s

Initial momentum = \(2kg\times (-5m/s)=-10kg.m/s\)

When the object is bounced back, the velocity is upward

v = +5m/s

Final momentum = \(2kg\times (+5m/s)=10kg.m/s\)

Change in momentum = Final - Inital

Change in momentum = [10 - (-10)] = +20 kg.m/s

Hence, the change in momentum is +20 kg.m/s

When working with specimens on a slide that have little or no color, it is important to adjust the light intensity appropriately to enhance visibility. Generally, using a higher level of light intensity is recommended in such cases. This can help to improve contrast and make it easier to see details of the specimen.

However, it is important to be cautious when using high levels of light intensity, as this can also cause the specimen to become overexposed and washed out. It is recommended to start with a moderate level of light intensity and gradually increase it until the specimen becomes more visible, but without causing any overexposure. Overall, finding the right balance between light intensity and specimen visibility is key to obtaining accurate observations and making the most of your microscopy work.

The speed of light in ethyl alcohol, which has a refractive index (n) of 1.36, is slightly slower than the speed of light in a vacuum, which is approximately 299,792,458 meters per second. To calculate the speed of light in ethyl alcohol, we can use the formula: v = c/n, where v is the velocity of light in the medium, c is the velocity of light in a vacuum, and n is the refractive index of the medium.

Using this formula, we can determine that the speed of light in ethyl alcohol is approximately 220,555,007 meters per second. This means that the speed of light is reduced by about 26% when it passes through ethyl alcohol. The reason for this reduction in speed is due to the increased density of the medium, which causes the light to slow down as it passes through.

Understanding the speed of light in different mediums is important in many fields of science and technology, including optics, telecommunications, and astronomy. By knowing the refractive index of a substance, we can determine how much light will be bent or refracted as it passes through, which can help us design and optimize various devices and systems.

Displacement and velocity are the two quantities that can be used to describe motion. Hence, option (A) is correct.

The term "displacement" refers to a shift in an object's position. It is a vector quantity with a magnitude and direction. The symbol for it is an arrow pointing from the initial location to the ending place.

The rate at which an object's position changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction.

Since it is a vector quantity, the definition of velocity requires both magnitude and direction.  A body is considered to be accelerating if its velocity changes, either in magnitude or direction.

Hence, motion of any object can be  fully explained by displacement and velocity.

So R₁ = 12² / 32.5 = 4.431 ohm

R₂ = 12² / 2 x 10³ = .072 ohm

when they are in series

Common Current in them = 12 / 4.431 + .072
