Explanation:
let us asume 2 balls here,
ball 1 and ball2
ball 1 is dropped from the lower hight
which means it's potential energy is low,where as the ball2 is dropped from higher height
and potential energy is higher than the ball 1which means ball2 has more force
by newton's 3rd lawwhich is, to every action there is an opposite reaction!
thus ball2 will bounce more!
How does wavelength change depending on whether the pipe is open or closed?
Answer:
* in a tube with both ends open
λ = 2L / n n = 1, 2, 3,…
* tube with one end open and the other closed.
λ = 4L / n n = (2n ’+ 1 )
Explanation:
When a sound wave enters a pipe, a resonance process occurs, whereby only some wavelengths can occur.
* in a tube with both ends open
in this case there are maximums at each end, so if the length of the had is L
λ = 2L 1st harmonic
λ = 2 L / 2 2nd harmonic
λ = 2L / 3
λ = 2L / n n = 1, 2, 3,…
* In the case of a tube with one end open and the other closed.
At the open end there is a belly and at the closed end a node
λ = 4L 1st harmonic
λ = 4L / 3 3rd harmonic
λ = 4L / 5
λ = 4L / n n = 1, 3, 5,… odd
n = (2n ’+ 1 ) where n’ are all integers

What is the third harmonic
frequency that it produces?
(Speed of sound = 343 m/s)
(Unit = Hz)
please help me guys will give brainliest and lots of points
Answer: The 180-Hz sinusoid is called the third harmonic, since its frequency is three times that of the fundamental frequency.
Explanation: Harmonics are integer multiples of the fundamental frequency. For example, if the fundamental frequency is 50 Hz (also known as the first harmonic) then the second harmonic will be 100 Hz (50 * 2 = 100 Hz), the third harmonic will be 150 Hz (50 * 3 = 150 Hz), and so on.

hours will it take the train to travel a distance of 160 kilometers?
Please provide the units with it
Answer:
2.5 hours
Explanation:
we know that the train travels 64km every hour so we just need to divide 160km by 64km to see how many hours it will take
160÷64= 2.5

Answer:
He not only hypothesized that lightning and electricity were linked, but that metal objects could be used to draw lightning in order to protect homes from being hit. But Franklin didn't feel that he could get his conductor high enough into the clouds to do any good, so he never completed the experiment.

Answer:
Climate.
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time.
The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.
The long-term average weather for a region is called climate.
This ultimately implies that, when the average atmospheric conditions prevailing in a specific region persists for a very long period of time, it is known as climate.

Explanation:
A locomotive is pulling 19 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (with its load) is 37,000 kg. If the train is accelerating at on a level track, what is the tension in the coupling between the second and third cars? (The car nearest the locomotive is counted as the first car, and friction is negligible.)
Explanation:
The tension between cars 2 and 3 accelerates cars 3 through 17. That is a total of 15 cars.F = M*a, with M = 15*37,000 = 555*10^3 kga = 0.7 m/s^2Solve for F, in Newtons

What would the volume of a gas be at –125oC, if it had a volume of 693 mL at 45oC?
Answer:
322.5mL
Explanation:
According to Charles's law, which state that at constant pressure the volume of fixed mass of a gas is proportional directly to it's temperature.
This can be expressed as
V1/ T1 = V2 / T2
Where
V1= initial volume= 693 mL
V2= final volume
T2= final temperature=( –125°C + 273)= 148K
T1= initial temperature= (45°C+ 273)=318K
V1/ T1 = V2 / T2
693/318 = V2/148
693×148 = 318 × V2
V2=102564/318
= 322.5mL

What ideas do you have about what determines how currents like this move?
While at the county fair, you decide to ride the Ferris wheel. Having eaten too many candy apples and elephant ears, you find the motion somewhat unpleasant. To take your mind off your stomach, you wonder about the motion of the ride. You estimate the radius of the big wheel to be 15 m, and you use your watch to find that each loop around takes 23 s.A. What is your speed?
B. What is the magnitude of your acceleration?
C. What is the ratio of your weight at the top of the ride to yourweight while standing on the ground?
D. What is the ratio of your weight at the bottom of the ride toyour weight while standing on the ground?
Answer:
Explanation:
From the given information:
radius = 15 m
Time T = 23 s
a) Speed (v) = [tex]\dfrac{2 \pi r}{T}[/tex]
[tex]v = \dfrac{2\times \pi \times 15}{23}[/tex]
v = 4.10 m/s
b) The magnitude of the acceleration is:
[tex]a = \dfrac{v^2}{r} \\ \\ a = \dfrac{(4.10)^2}{15}[/tex]
a = 1.12 m/s²
c) True weight = mg
Apparent weight = normal force
From the top;
the normal force = upward direction,
weight is downward as well as the acceleration.
true weight - normal force = ma
apparent weight =mg - ma
[tex]\dfrac{apparent \ weight}{true \ weight} = \dfrac{(mg - ma)}{(mg)}[/tex]
[tex]=1- \dfrac{1.12}{9.8}[/tex]
= 0.886 m/s²
d)
From the bottom;
acceleration is upward, so:
apparent weight - true weight = ma
apparent weight = true weight + ma
[tex]\dfrac{apparent \ weight }{true \ weight} =\dfrac{ mg + ma}{mg}[/tex]
[tex]\dfrac{apparent \ weight }{true \ weight} =1+ \dfrac{a}{g} \\ \\ = 1 + \dfrac{1.12}{9.8}[/tex]
[tex]= 1 + \dfrac{1.12}{9.8} \\ \\[/tex]
= 1.114 m/s²
A boundary with a small opening. There is a vector straight from the opening labeled D and an angle labeled theta to another ray, both striking a surface with a red point. The distance between the two red points is labeled y. A laser diffraction pattern results in y = 6.0 cm, and the distance from the gap to the screen is D = 12 cm. The tangent of θ would be equal to . Calculating the inverse (tan–1) of the value for the tangent of θ would give us a diffraction angle, θ, of degrees.
Answer:
The tangent of θ would be equal to 0.5
Calculating the inverse (tan–1) of the value for the tangent of θ would give us a diffraction angle, θ, of 27 degrees.

Electromagnets are an example of how electricity can create magnetism is True statement.
What is Electromagnet?Permanent magnets are not the same as electromagnets. Coils of wire with electricity running through them make up electromagnets. An electromagnet's wire coils act like magnets when an electric current flows through them because moving charges produce magnetic fields.
The coils stop functioning as a magnet when the electricity is turned off. When magnetic forces are only required for brief periods of time, electromagnets are frequently used in electrical equipment.
They both make use of electromagnets, which use electricity to apply a magnetic field. Extremely strong electromagnets are used by wrecking yards to transfer heavy scrap metal or even entire cars from one location to another.
Therefore, Electromagnets are an example of how electricity can create magnetism is True statement.
