Choose one object or instrument. Write a detailed explanation of what happens when a loud and quiet sound is made. Use the words vibration, energy, longitudinal wave, amplitude and particles in your answer.
Answer:
This extra energy causes the string to vibrate more, which helps it move more air particles for a longer time. A string plucked with force has greater amplitude, and greater amplitude makes the sound louder when it reaches your ear. Volume depends on amplitude. Greater amplitude produces louder sounds.

Describe the relationship between frequency and wavelength
Answer:
Frequency and wavelength are inversely related.
Explanation:
Frequency and wavelength have an inverse relationship because if one thing goes up another goes down. For example, if frequency goes up, the wavelength goes down and vice versa.
Answer:
The relationship between wavelength and frequency is that the frequency of a wave multiplied by its wavelength gives the speed of the wave.
Explanation:
Frequency and wavelength are related terms also, used to describe electromagnetic radiation or light. One simple equation is used to convert between them: frequency x wavelength = speed of light. λ v = c, when λ is wavelength, v is frequency, and c is the speed of light.

What is a good analogy for potential energy in a circuit?
Answer: find the answer in the explanation
Explanation: The potential energy in a circuit between two points is the workdone in taking units positive charge from one point to the other in the circuit. Its S.I unit is Joule.
Because voltage of a battery or cell in a circuit is the potential energy difference across its terminal
The potential energy difference between two points is one volt, if the workdone in taking one Coulomb of positive charge from one point to the other is one Joule.

Which graph shows the correct relationship between kinetic energy and speed?
Answer: D
Explanation:
Kinetic energy = 1/2mV^2
From the formula above, we can deduce that kinetic energy is proportional to the square of speed. That is,
K.E = V^2
Graphically, the relationship isn't linear but a positive exponential. Therefore, option D is the correct answer.

At which point is the potential energy the greatest? At which point is kinetic energy the greatest?
Answer:
Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.
hope it helps you make me as brainlylistPotential energy will be greatest at the points A and G, and kinetic energy will be greatest at the point D.
• The energy possessed by an object due to its motion is termed as the kinetic energy. On the other hand, the energy stored within an object because of its position relative to some zero position is known as the potential energy of the object.
• Kinetic energy is highest when the velocity is the highest, in the case of pendulum, this takes place at the bottom. In the given case, that is, at point D.
• If kinetic energy is highest at point D, then at the same point potential energy will be the lowest.
• Therefore, potential energy would be highest at its highest point on each of the side of its motion where it remains stationary for some time, that is, at point G and A.
Thus, kinetic energy would be highest at point D, and potential energy would be highest at the points A and G.

How do you inhibitors work
Answer:
By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalyzation of reactions and decreasing (at times to zero) the amount of product produced by a reaction.
Explanation:
A mover uses a ramp to load a crate of nails onto a truck. The crate, which must be lifted 1.5 m from the street to the bed of the truck, is pushed along the length of the ramp. If the ramp is 4.5 m long and friction between the ramp and crate can be ignored, what is the mechanical advantage of the ramp?
Answer: M.A = 3
Explanation:
A ramp is an example of an inclined plain. Where the
Height H = 1.5 m
Length L = 4.5 m
Mechanical advantage of a machine is the ratio of the load to effort. While mechanical advantage M.A of an inclined plain is the ratio of the length of the plain to the height of the plain.
M.A = L/H
Substitute the values of L and H into the formula
M.A = 4.5/1.5 = 3
The mechanical advantage of the ramp is 3

9. A ball is thrown straight up with an initial speed of 30 m/s. How long will it take to reach the top of its trajectory, and high will the ball go?
Answer:
1.) Time t = 3.1 seconds
2.) Height h = 46 metres
Explanation:
given that the initial velocity U = 30 m/s
At the top of the trajectory, the final velocity V = 0
Using first equation of motion
V = U - gt
g is negative 9.81m/^2 as the object is going against the gravity.
Substitute all the parameters into the formula
0 = 30 - 9.81t
9.81t = 30
Make t the subject of formula
t = 30/9.81
t = 3.058 seconds
t = 3.1 seconds approximately
Therefore, it will take 3.1 seconds to reach to reach the top of its trajectory.
2.) The height it will go can be calculated by using second equation of motion
h = ut - 1/2gt^2
Substitutes U, g and t into the formula
h = 30(3.1) - 1/2 × 9.8 × 3.1^2
h = 93 - 47.089
h = 45.911 m
It will go 46 metres approximately high.

Which one of the following is not equivalent to 2.50 miles?
(1.00 mi = 1.61 km = 5280 ft, 1.00 yd = 3.00 ft = 12.0 in.)
(A) 1.32 x 104 ft
(B) 1.58 x 105 in
(C) 4.02 x 103 km
(D) 4.40 x 103 yd
(E) 4.02 x 105 cm
Answer:
Choice C is not equivalent to 2.50 miles.
Explanation:
The given data is now converted into feet, inches, kilometers, yards and centimeters:
mi - ft
[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi} \right)[/tex]
[tex]x = 13200\,ft[/tex]
[tex]x = 1.320\times 10^{4}\,ft[/tex] (Choice A)
mi - in
[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi} \right)\cdot \left(12\,\frac{in}{ft} \right)[/tex]
[tex]x = 158400\,in[/tex]
[tex]x = 1.584\times 10^{5}[/tex] (Choice B)
mi - km
[tex]x = (2.50\,mi)\cdot \left(1.61\,\frac{km}{mi} \right)[/tex]
[tex]x = 4.025\,km[/tex] (Different from Choice C)
mi - yd
[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi}\right) \cdot \left(\frac{1}{3}\,\frac{yd}{ft} \right)[/tex]
[tex]x = 4400\,yd[/tex]
[tex]x = 4.40\times 10^{3}\,yd[/tex] (Choice D)
mi - cm
[tex]x = (2.50\,mi)\cdot \left(1.61\,\frac{km}{mi} \right)\cdot \left(100000\,\frac{cm}{km}\right)[/tex]
[tex]x = 402500\,cm[/tex]
[tex]x = 4.025\times 10^{5}\,cm[/tex] (Choice E)
Choice C is not equivalent to 2.50 miles.

how much work must be done by frictional forces in slowing a 1000-kg car from 26.1 m/s to rest?
Answer:
Explanation:
Work done by the frictional force is 3.41x10^5 J
It is given that,
Mass of the car, m = 1000 kg
Initial velocity of car, u = 26.1 m/s
Finally, it comes to rest, v = 0
We have to find the work done by the frictional forces. Work done is equal to the change in kinetic energy as per work - energy theorem i.e.
W = −340605 J
or Hence, the correct option is (a).
A ball rolls with a speed of 4.0 m/s across a level table that is 1.0 m above the floor. Upon reaching the edge of the table, it
follows a parabolic path to the floor. How many meters along the floor is the landing spot from the table?
Answer: 1.81m
Explanation:
Given the following:
Horizontal speed = 4m/s
Height of table = 1m
Taking the vertical component of the motion:
Using:
S = ut + 0.5 at^2
Where, S = height of table, a = acceleration due to gravity (9.8m/s^2), t = time and u = Initial Velocity in vertical direction = 0
1 = 0(t) + 0.5(9.8)t^2
1 = 4.9t^2
t^2 = 1 / 4.9
t^2 = 0.204081
t = sqrt(0.204081)
t = 0.452s
For Horizontal :
Gravitational acceleration is absent, therefore distance can be calculated using:
Distance = Velocity × time
Distance = 4m/s × 0.452s
Distance = 1.808 m
Distance = 1.81m

why does a bouncing ball have a greater change in momentum than a ball that is just caught
If the ball bounces, then there is an additional velocity change sending the ball back upwards opposite the original direction. Thus, for the same collision time, bouncing involves a greater velocity change, a greater momentum change, and therefore a greater impulse.
Answer:
because with the change in momentum the velocity goes to zero. (more info below)
Explanation:
Momentum is the velocity change multiplied by the mass. When you think about it, bouncing an object means it comes back from anything it bounced against, giving it a velocity that is negative. This means that the velocity change for bouncing is greater than for colliding, as the velocity goes to zero in an inelastic collision like the one described.
