how does electricity work?
Answer:Electricity works by getting a bunch of conductor elements together and creating a flow of electron-stealing patterns through them. This flow is called a current. ... Once you can control the direction the electrons are going, you can use them to power or charge anything from a light bulb to your TV to your electric car.

Suppose you needed to push a 1,500-N sofa up a frictionless ramp with a 30° angle. How much force would you have to apply to the sofa?Show your work below.
Answer:
1299N
Explanation:
GIven data
Weight W= 1500N
Angle Ф= 30°
The applied force up the frictionless ramp is gotten by applying the formula below
F= WcosФ
substitute
F=1500 cos 30
F = 1500*0.8660
F= 1299N
Hence the applied force is 1299N
A 905 kg test car travels around a 3.25 km circular track. if the magnitude of the force that maintains the car's circular motion is 2140 N, what is the car's tangential speed?
An effect analogous to two-slit interference can occur with sound waves, instead of light. In an open field, two speakers placed 1.19 m apart are powered by the same function generator producing sine waves at 1,163 Hz frequency. Assume that the speed of sound is 340 m/s. A student walks along a line 12.5 m away and parallel to the line from one speaker to the other speakers. She hears an alternating pattern of loud and quiet, due to constructive and destructive interference. What is the distance between the central maximum and the first maximum (loud) position along this line in m
Answer:
3.04 m
Explanation:
The interference by diffraction of waves is noticeable only when the dimension of the opening through which the wave is passing through is comparable to the wavelength of the passing wave.
It is given that :
Distance between two speakers, d = 1.19 m
Speed of sound, v = 340 m/s
The frequency is f = 1163 Hz
Distance the student walk along the line of the speaker, D = 12.5 m
We know the wavelength of the sound produced by the speakers is given by :
[tex]$\lambda=\frac{v}{f}$[/tex]
[tex]$=\frac{340}{1163}$[/tex]
= 0.29 m
Now the distance between the central maximum and the first maximum position is given by :
[tex]$y=\frac{\lambda D}{d}$[/tex]
[tex]$=\frac{0.29 \times 12.5}{1.19}$[/tex]
= 3.04 m
under which conditions do both convex and concave mirrors form virtual images state whether or not each can form a real image if the mirror can form a real image describe how this occurs
Answer:
Explanation:Concave mirrors can make a real image.when the object is away from the mirror it is called real image and when the object is closer to the mirror it is called virtual mirror.
How was our galaxy formed?
Answer:
according to big bang theory our galaxy was formed 13billion years ago and then made the stars and galaxies we see today. ... The universe began as a very hot, small, and dense superforce (the mix of the four fundamental forces), with no stars, atoms, form, or structure (called a "singularity).

Which type of wave interaction is shown in the photo?
A. Interference
B. Refraction
C. Reflection
D. Diffraction
Answer: the answer is c (think bc im on that too)
Explanation:
The interference is a type of wave interaction shown in the photo. Option A is correct.
What is the interference of waves?The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.
The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.
When two wave pulses are traveling along a string toward each other. They meet and the phenomenon is occur known as interference.
The interference is a type of wave interaction shown in the photo
Hence option A is correct.
