which statement best describes the position of the image of an object viewed in a plane mirror?
A). the image is a different distance from the mirror but on the same side of the mirror as the original object
B). the image is the same distance from the mirror and on the same side of the mirror as the original object
C). The image is a different distance from the mirror and on the other side of the mirror as the original object.
D). the image is the same distance from the mirror but on the other side of the mirror as the original object.
The statement D best describes the position of the image of an object viewed in a plane mirror, The image is the same distance from the mirror but on the other side of the mirror as the original object.
What is the image?When light beams from an object reflect off a mirror, they intersect with the picture of that thing, called an image. Real and virtual images are the two sorts of images.
The following parameters can be used to describe an image:
1. It is possible for an image to be real or virtual.
2. Left-right reversal is possible or not.
3. The image can be inverted or upright.
4. The image can be enlarged, shrunk, or made the same size as the object.
Plane mirrors provide virtual images that are upright, inverted left-right, the same distance from the mirror as the item, and the same size as the thing.
As a result, the best description of image production by a plane mirror is “a virtual picture is produced behind the mirror.”
The statement D best describes the position of the image of an object viewed in a plane mirror, The image is the same distance from the mirror but on the other side of the mirror as the original object.
Hence, option D is correct.

Which field of science gives us the idea that spacetime is not just a flat grid but is
itself a physical entity that can be bent and molded?
A: General Relativity
B: Time dilation
C: quantum mechanics
D: gravitational physics
The field of science that gives us the idea that spacetime is not just a flat grid but is itself a physical entity that can be bent and molded is known as quantum mechanics. Thus, the correct option for this question is C.
What is Quantum mechanics?Quantum mechanics may be defined as a fundamental theory in physics that significantly provides a detailed description of the physical properties of nature at the scale of atoms and subatomic particles. It is basically the branch of physics that deals with the behavior of matter and light on a subatomic and atomic level.
Time dilation in the theory of special relativity is the “slowing down” of a clock as determined by an observer who is in relative motion with respect to that clock.
General relativity is the theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.
Therefore, quantum mechanics is the field of science that gives us the idea that spacetime is not just a flat grid but is itself a physical entity that can be bent and molded. Thus, the correct option for this question is C.

Answer:
Explanation:
1. If we increase the distance to twice it's original value, the light intensity is reduced by one-fourth, the light intensity would be:
I0/4
2. rms magnetic field is inversely proportional to distance, so the new rms magnetic field would be:
B0/2
3. average energy density is inversely proportional to the square of the distance, so the new average energy density is:

Answer:
Diagram B because a plate resting on a table has gravity acting on it and normal/air resistance force working against the gravity with the same amount of force. Forces that are balanced don't move.
Explanation:
I hope this helps
Diagram B represents the forces acting on the plate that is at rest on the kitchen table.
What is normal force?Every day, we experience the normal force.
In this instance, when we lay a plate on a kitchen table, the normal response force prevents the plate from going through the table, even if gravity is pulling the plate downward. That implies that there is a force acting to push it upward. The word "normal force" refers to the force. Normal in this context refers to being perpendicular to the ground.
Hence, in diagram B, downwards arrow represents gravitational force acting on the plate for its weight and upwards arrow represents normal force acting on the plate by the table.

An electromagnetic am-band radio wave could have a wavelength of.
An electromagnetic AM-band radio wave could have a wavelength of 186.6 meters.
Wavelength is the distance between two consecutive points on a wave that are in phase, meaning they are at the same position in their respective cycles. It is usually denoted by the Greek letter lambda (λ) and is measured in units of length, such as meters, centimeters, or nanometers.
The relationship between wavelength, frequency, and speed of a wave is given by the formula:
wavelength = speed / frequency
where "speed" refers to the speed of the wave through a medium, and "frequency" refers to the number of cycles per second.
The AM radio band frequency ranges from 535 kHz to 1605 kHz. To find the wavelength of the AM radio wave, we can use the formula:
wavelength = speed of light / frequency
where the speed of light is approximately 299,792,458 meters per second.
Let's take the highest frequency in the AM radio band, which is 1605 kHz. We need to convert this frequency to Hertz (Hz) by multiplying it by 1000 since kHz is 10^3 times larger than Hz.
1605 kHz = 1605 x 1000 Hz = 1,605,000 Hz
Now, we can calculate the wavelength of the AM radio wave using the formula:
wavelength = 299,792,458 / 1,605,000
wavelength ≈ 186.6 meters
Therefore, an electromagnetic AM-band radio wave could have a wavelength of approximately 186.6 meters.
