Is the distance we walk equal to the magnitude of our displacement?
Answer:
If you take the first example of the walk around the desk, it should be apparent that sometimes the distance is the same as the magnitude of the displacement. ... Since the displacement is measured along the shortest path between two points, its magnitude is always less than or equal to the distance.

Compare and Contrast electromagnetic waves to infer the relationship between frequency, energy, and wavelength.
Answer:
Explanation:This question is simply asking you to describe the following equations:
E = hv
v = c/L
E = hc/L
where E is the energy, h is Planck's constant, v is the frequency, c is the speed of light and L is the wavelength.
By looking at the equations you should be able to tell what the relationships between energy, frequency and wavelength are. If you are having difficulty describing them, then create a table with actual values and see what happens to the energy as you increase or decrease the frequency and/or wavelength.
If a ball is tossed straight up into the air, at what position is its potential energy the greatest? Question 3 options: When it begins to fall back to your hand when it approaches the top of its flight when it reaches the top of its flight when it first leaves your hand.
The ball has the greatest potential energy when it reaches the top of its flight. Option C is correct.
What is potential energy?The potential energy of a body or object is due to its position. The ball has the greatest potential energy when it reaches the highest point.

7. A stationary 25 kg object is located on a table near the surface of the earth. The coefficient of static friction between the surfaces is 0.50 and of kinetic friction is 0.30. A horizontal force of 300 N is applied to the object. Determine the force of friction. *
Answer:
73.5 N opposite the applied force
Explanation:
The normal force the object exerts on the table is ...
F = ma
F = (25 kg)(9.8 m/s^2) = 245 N
The force required to overcome the static friction and set the object in motion is ...
(0.50)(245 N) = 122.5 N
The applied force is more than sufficient for that purpose, so we must assume the object is being accelerated.
The force of friction while the object is in motion is ...
(0.30)(245 N) = 73.5 N . . . opposing the applied horizontal force
_____
Additional comment
Friction force is in the direction opposite to the direction of motion along a surface. The magnitude of it is the product of the coefficient of (static or kinetic) friction and the normal force between the surface and the object. Usually, the coefficient of static friction is greater than that of kinetic friction. (Once an object is set in motion, it usually takes less force to keep it in motion.)

The statement that true is (A). All forms of electromagnetic radiation travel at the same speed in a vacuum.
IntroductionElectromagnetic waves have an energy that is carried in energy packets. The energy that was carried is called photon energy. Photon energy is influenced by three factors, namely:
The speed of light (c), actually the speed of light is a constant (fixed value), if it is in a vacuum. So, when in a vacuum, the value of c will always be the same. The harder the medium through which electromagnetic waves pass, the faster the wave speed will decreaseFrequency (f), the frequency will be proportional to the energy of the photon carried. The greater the frequency, the more vibrations that occur every second. The heat due to this vibration is part of the photon energy.Wavelength ([tex] \sf{\bold{\lambda}} [/tex]), The wavelength of the value will be inversely proportional to the energy of the photon. The shorter the wavelength, the greater the energy of the photons it carries.ExplanationBased on these concepts, the photon energy equation is obtained as follows :
By Frequency[tex] \boxed{\sf{\bold{E = h \times f}}} [/tex]
By the Wave Length[tex] \boxed{\sf{\bold{E = h \times \frac{c}{\lambda}}}} [/tex]
With the following condition :
E = photon energy (J)h = Planck's constant ≈ [tex] \sf{6.6 \times 10^{-34} \: J.s} [/tex]c = the constant of the speed of light in a vacuum ≈ [tex] \sf{3 \times 10^{8} \: m/s} [/tex]f = electromagnetic wave frequency (Hz)[tex] \sf{\lambda} [/tex] = wavelength (m)ConclusionSo, if you are in a vacuum, only the speed of propagation of electromagnetic waves is the same. Photon energy, only affected by wavelength and/or frequency.

what is the difference between gravitational force and the force of gravity
This might help and it might not:
Gravitation is the acting force between two bodies. On the other hand, gravity is the force occurring between an object and the very big object earth. Every object with some mass exerts the gravitational force on every other object having some mass. This force and its strength depend on the masses of the objects under consideration. Gravity helps to keep the planets to move in their orbit around the sun.
Gravitation is the force of attraction between any two bodies in the universe. In our universe, each object attracts each other with a certain amount of force. The large distance of separation is the main reason for its weak nature.
Gravity is the weakest type of fundamental force in nature. Still, it holds together the entire solar systems and galaxies.
Gravity has the existence with unlimited range.
A satellite camera in space took this picture of northwestern Algeria, showing an impact crater, sedimentary
rock layers, and a stream channel flowing out of the crater. Algeria is at the northern end of the African
continent. The Algerian landscape includes a large portion of the Sahara Desert and two mountain ranges.
A. An ancient stream channel left deposits that built up over time to form the sedimentary rocks surrounding the stream. A meteorite's impact changed the direction that the stream flowed, which led to mountain ranges forming downstream from the crater.
B. Lava flows from volcanic eruptions created sedimentary rock layers; heavy rains formed a stream channel; and a meteorite's impact evaporated the stream water, leaving the area without a water source and creating a desert.
C. A meteorite impacted Earth, creating a low- lying area where water filled in to create a stream channel. The stream channel carried sediment with it, eventually forming the surrounding layers of sedimentary rock.
D. Layers of sediments were compacted to form sedimentary rock; a meteorite impacted Earth after the sedimentary layers were
formed; and water erosion formed a stream channel from the meteorite's impact zone.
It is observed that sedimentary rock was generated by compacting sedimentary layers; a meteorite struck Earth after the sedimentary layers developed. Option D is correct.
What Exactly Is a Satellite Camera?Space is captured by satellite camera systems in a variety of electromagnetic frequencies.
A satellite imager, in fact, is a detector equipped with a sensor that actively scans the changing surface of the Earth, registering the signal generated or reflected by the item or the surrounding region.

Introduction :Hi ! We all know that all type of electromagnetic wave, will have the same velocity as the speed of light, because light is part of electromagnetic wave too. The value of it is 300,000 km/s or [tex] \sf{3 \times 10^8} [/tex] m/s. As a result of this constant property, the shorter the wavelength, the greater the value of the electromagnetic wave frequency. This relationship can also be expressed in this equation:
[tex] \boxed{\sf{\bold{c = \lambda \times f}}} [/tex]
With the following condition :
c = the constant of the speed of light in a vacuum ≈ [tex] \sf{3 \times 10^{8} \: m/s} [/tex] m/s[tex] \sf{\lambda} [/tex] = wavelength (m)f = electromagnetic wave frequency (Hz)ExplanationIn this problem, we underline one concept, namely : "the shorter the wavelength, the greater the value of the electromagnetic wave frequency". In question, the frequency of the waveform will increase by a factor of 3 from the beginning. So, to keep this value constant, the wavelength should be reduced by a factor of 3 from the initial condition.
ProofAssume that:
c = c' = speed of the electromagnetic wave is always the same (constant).[tex] \sf{\lambda} [/tex] = initial wavelength = [tex] \sf{\lambda} [/tex]f = initial frequency = ff' = final frequency = 3fLet we count :
[tex] \sf{\lambda}' [/tex] = final wavelength = ... [tex] \sf{\lambda} [/tex]Step by step :
[tex] \sf{c = c'} [/tex]
[tex] \sf{\lambda \times f = \lambda' \times f'} [/tex]
[tex] \sf{\cancel{\lambda} \times \cancel f = x \cancel{\lambda} \times 3 \cancel{f}} [/tex]
[tex] \sf{1 = 3x} [/tex]
[tex] \sf{x = \frac{1}{3}} [/tex] (Q.E.D)
ConclusionSo, if the frequency value is increased by a factor of 3 from its original, then the wavelength will decrease by a factor of 3 from the original.
