A periodic wave is a wave that follows a repeating pattern as it propagates through space. That is, the oscillating pattern repeats at regular intervals of time. This repeating motion is also known as periodic motion
Answer:
Simple harmonic motionExplanation:
What is simple harmonic motion?
"Simple harmonic motion is a type of motion directed along a straight line, whose acceleration is fixed towards a point and is proportional to its distance from that point"
An object is said to be in simple harmonic motion if the following occurs:
• It moves in a uniform path.
• A variable force acts on it.
• The magnitude of the force is proportional to the displacement of the mass.
• The force is always opposite in direction to the displacement direction.
• The motion is repetitive and a round trip, back and
forth, is always made in equal time periods

What current flows through a bulb if 360 C of charge moves through
a bulb in 20 minutes?
Answer: A current of 1 A is flowing in a circuit if a charge of 1 coulomb passes any point in the circuit every second.
1 Amp = 1 Coulomb per second
We can write this formula as:
Current (I) = Charge (Q) / Time (t)
Charge (Q) = Current (I) x Time (t)

I WILL MARK BRAINLIEST!!ASAP!!! Wet Lab - Coulomb's Law lab from edge!!
Answer: nah
Explanation:
A wet lab experiment for Coulomb's law involves measuring the force between charged objects immersed in a liquid. The experiment is called a "wet" lab because it involves liquid or aqueous solutions.
What is Coulomb's law?Coulomb's law is an equation that describes the electrostatic force between two charged particles.
It states that "the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them."
The equation is given by:
F = k×(q₁ × q₂) / r²
Where
F = the electrostatic force,
k =Coulomb's constant,
q₁ and q₂= the charges of the particles,
r =the distance between the.
In this question,
In the experiment, two conductive objects are charged with opposite charges using a high-voltage power supply, which can be controlled to vary the magnitude of the charges.
The two objects are then immersed in a non-conductive liquid, such as oil or water, and positioned a fixed distance apart.
Using a force sensor or a balance, the force between the two objects is measured as they move toward each other. By measuring the force at different distances, the experiment can verify Coulomb's law, which predicts that the force between two charged objects is proportional to the product of their charges and inversely proportional to the square of their separation distance.
The experiment can be performed with different pairs of charged objects with different magnitudes of charge and separation distances, allowing the relationship between the force and these variables to be investigated. This provides insight into the electrostatic interaction between charged objects in a liquid, which has applications in various fields, including electrochemistry, material science, and biophysics.
Therefore, in a wet lab experiment on Coulomb's law, we have to immerse the apparatus in aqueous solutions.

You are designing a rotor ride for an amusement park. What design will enable the rider to feel the greatest Fn (Normal Force)?
a. Decrease the velocity of the ride and increase the radius
b. Decrease the velocity of the ride and decrease the radius
c. Increase the velocity of the ride and increase the radius
d. Increase the velocity of the ride and decrease the radius
Answer:
d. Increase the velocity of the ride and decrease the radius
Explanation:
The normal force in the amusement park ride is produced by the centripetal force. The formula for this force is given as follows:
Fn = mv²/r
where,
m = mass of the body,
v = velocity of the body
r = radius of the path
Therefore, it is clear from the formula that force has a direct relation with the square of velocity and inverse relation with the radius of path. Hence, the design that will enable the rider to feel the greatest Fn will be:
d. Increase the velocity of the ride and decrease the radius

A car initially traveling at 25 m/s speeds up to 60 m/s under a uniform acceleration of 5.0 m/s2 to avoid being hit by another car. How long does it take the car to speed up and get out of the way? Show your work.
Answer:
The car takes 7 seconds to speed up and get out of the way
Explanation:
Constant Acceleration Motion
It's a type of motion in which the velocity of an object changes uniformly over time.
Having a as the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
v_f=v_o+at
Using the above equation we can solve for t:
[tex]\displaystyle t=\frac{v_f-v_o}{a}[/tex]
The car has an initial speed of vo=25 m/s and ends up at vf=60 m/s with an acceleration of a=5 [tex]m/s^2[/tex].
Given all the appropriate data, calculate t:
[tex]\displaystyle t=\frac{60-25}{5}[/tex]
Calculating:
[tex]\displaystyle t=\frac{35}{5}[/tex]
t = 7 seconds
The car takes 7 seconds to speed up and get out of the way
An eagle is flying horizontally 16.4 meters above a lake at a speed of 9.3 m/s, carrying a small pumpkin in its talons. The pumpkin slips free. How far horizontally will the pumpkin travel after it slips from the eagle until it hits the ground?
Answer:
The horizontal distance the pumpkin will travel after it slips from the eagle is 17.02 m
Explanation:
Given;
height above the ground, h = 16.4 m
speed of the eagle, v = 9.3 m/s
The time it will take the pumpkin to fall at the given height is calculated as;
[tex]t = \sqrt{\frac{2h}{g} }\\\\t = \sqrt{\frac{2*16.4}{9.8} }\\\\t = 1.83 \ s[/tex]
The horizontal distance traveled at this time is given by;
x = vt
x = (9.3)(1.83)
x = 17.02 m
Therefore, the horizontal distance the pumpkin will travel after it slips from the eagle is 17.02 m

OC wykonuje około 112 pełnych wahnięć skrzydłami w ciągu jednej sekundy Zaznacz poprawne dokończenie zdania okres drgań skrzydeł osy wynosi około a 112 sekund b 112 h z c9n s d 0,009 h l z
Answer:
T = 0.009 s
Explanation:
It is given that, an OC makes about 112 full wing swings in one second. We need to find the oscillation period of the wasp's wings.
No of oscillations per unit time is called the frequency of an object. It means 112 is the frequency of wing swings. Let T is the oscillation period. It is equal to the reciprocal of frequency as follows :
[tex]T=\dfrac{1}{f}\\\\T=\dfrac{1}{112}\\\\= 0.00892\ s\\\\=0.009\ s[/tex]
Hence, the oscillation period is 0.009 s.

An electric heater takes 1.2kwh in 30min at 120V having an efficiency of 99%.The heat energy required boil a certain amount of water is 99KJ.If the current taken by heater is 20 amp at 120V.Find the time required to boil water?
Answer:
Explanation:
Power of the heater = P watt .
P x .5 = 1200
P = 2400 W
If resistance of heater R
V² / R = 2400
120²/ R = 2400
R = 6 ohm .
heat to be produced = 99000 J
Current be I
I²R t x .99 = 99000
20² x 6 x t x .99 = 99000
t = 41.67 s
