Answer:
Explanation:
A change in an object’s motion—such as Xander speeding up on his scooter—is called acceleration. Acceleration occurs whenever an object is acted upon by an unbalanced force. The greater the net force acting on the object, the greater its acceleration will be, but the mass of the object also affects its acceleration. The smaller its mass is, the greater its acceleration for a given amount of force. Newton’s second law of motion summarizes these relationships. According to this law, the acceleration of an object equals the net force acting on it divided by its mass.
What is the charge on an object that experiences a force of 5 Newtons in an electric field of 50 Newtons per coulomb?
Answer:
Explanation:
F = qE
F is the force in Newtons
q is the test charge
E is the electrical field produced by the source charge
[tex]5=q(50)\\q=1*10^-^1Coulombs[/tex]
The magnitude of charge on the object is of 0.1 C.
Given Data:
The magnitude of electric field is, E = 50 N/C.
The magnitude of Electric force is, F = 5 N.
The region where any particle feels the effect of electric force on itself, due to other charged entities, is known as Electric field. And the relation between the electric force and electric field is given as,
F = E × q
Here,
q is the magnitude of charge on the object.
Solving as,
q = F/E
q = 5 / 50
q = 0.1 C
Thus, we can conclude that the magnitude of charge on the object is of 0.1 C.

Given that the frequency of an Em wave is 4THz, what is its wavelength? a) 75,000um b) 75,000nm c) 75,000pm d) 75,000A
Answer:
λ = 75 µm, correct is A
Explanation:
In waves, speed is related to wavelength and frequency
c = λ f
λ = c / f
in this exercise indicate the frequency of rationality
f = 4 THz = 4 10¹² Hz
let's calculate
λ = 3 10⁸/4 10¹²
λ = 7.5 10⁻⁵ m = 75 10⁻⁶ m
λ = 75 µm

PLS HELP!!! Response: Develop a unique example (not posted on the discussion board by anyone else) and calculate the resultant displacement between two points when there are two legs or distinct parts to the trip. Include the displacement of each leg of the trip as well as the resultant displacement of the entire trip. Don't forget: include both the direction and the magnitude as part of the displacement. Research the actual distance between these two points on the globe. Compare the resultant displacements and account for the error. Don't forget: include both the direction and the magnitude as part of the displacement.

how high is the pole from which the lamp fell freely if it hits the ground at a speed of 15 m/s
Answer & Explanation:
The acceleration due to gravity is about 10 m/s^2.
That means a the speed of a falling object will increase by 10 m/s every second that it falls.
We know that the lamp hits the ground at 15 m/s.
That means the lamp has been falling for
[tex]\frac{15 m/s}{10 m/s^{2} } = 1.5 s[/tex]
Now we use the formula [tex]h = \frac{1}{2} gt^{2}[/tex] to calculate the height, where
h is the height
g is the acceleration due to gravity and
t is the time taken to fall a height of h.
h = 1/2 x 10 x 1.5^2 = 11.25 m

What is elastic potential energy and give and a example
Answer:
Many objects are designed specifically to store elastic potential energy, for example: The coil spring of a wind-up clock. An archer's stretched bow. A bent diving board, just before a divers jump
Explanation:
Answer:
Elastic Potential Energy is stored in elastic items.
A example of Elastic Potential Energy is a rubber band. When you stretch it, and it shoots off your finger. Where the rubber band gives off Elastic Potential Energy, is when you stretch it on your fingers, before you let it go.

Dogs can hear sounds that we can't. Research dogs and find out what frequencies they can hear. Write down what you find out. Using what you just learned, write a short story on what it might be like to be a dog. Include a description of what you might hear and how it might affect you if you were a dog. Your story can be fictional or nonfictional - it can be whatever you want it to be! Take some time to listen to sounds in your environment. Make a list of ten sounds, ranking them from the highest pitch to the lowest. Write a couple of sentences describing whether this was easy or difficult and why.
Answer:
I did this essay before, its not hard. Just read through it carefully and you'll figure it out. or just ask you mom, dad, guardian, or teacher for help
The human ear can hear the frequency range of 20 Hz to 20 kHz and dogs can hear up to the range of 40Hz up to 50,000Hz or even 60,000Hz. Compared to humans, dogs have a significantly wider range of hearing.
What is sound?Sound is a mechanical disturbance that travels through an elastic medium and disrupts an equilibrium condition. It is also feasible to define sound solely subjectively, as that which is perceived by the ear.
Although this definition lacks clarity and is overly pedantic because it is necessary to discuss noises that cannot be heard by the human ear, such as those made by dog whistles or sonar devices.
Given:
Dogs can hear sounds that we can't,
While small toddlers can hear noises exceeding 20,000 Hertz (Hz), the average adult cannot. (The frequency of a sound is measured in Hertz, and the greater the frequency, the higher pitched the sound.) Dogs, on the other hand, are capable of hearing frequencies between 40Hz up to 50,000Hz or even 60,000Hz.
