When a guitar string is plucked, sound waves, which are mechanical waves, transmit sound to your ears. What is the primary medium through which the sound waves travel?
The primary medium through which the sound waves travel is
Air.
What is a Wave?A wave is defined as a disturbance that travels through a
medium which transports energy from one place to another in
the process.
In a guitar, the vibration of the string sets the surrounding air
molecules into vibrational motion which thereby produces
sound heard.

What are earthworms?Earthworms are common soil dwellers who are both safe and useful. Earthworms help plants flourish by collapsing dead and decaying organic debris into rich humus soil.
They also aerate the soil and enhance flow by digging small canals and holes.
The four regions of the earthworm are;
A is the Anterior end
B is the Dorsal side
C is the Posterior end
D is the Ventral side
Hence all the regions are clearly defined with the help of digrame.

True or False. The fulcrum of a first class lever is between the output force and an input force.
Answer:
True
Explanation:
A first-class lever is a lever in which the fulcrum is located between the input effort and the output load. In operation, a force is applied (by pulling or pushing) to a section of the bar, which causes the lever to swing about the fulcrum, overcoming the resistance force on the opposite side
Where would you expect to find volcanic mountain ranges and why?
Answer:
Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”
Explanation:
Volcanoes are found around tectonic plates because the convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other, plates converge and the plates move together, also known as ridge push, therefore mountains and volcanoes are formed

which of the following correctly describes the hierarchy of genetic material within a cell
Answer: D- Each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA
Explanation:
A macromolecule is a large molecule that is made of many smaller units. Chromosomes are macromolecules that contain all of the genetic information in a cell. Chromosomes are each made of two smaller units called chromatids. Chromatids are each made up of molecules of DNA. Therefore, the correct description of the hierarchy of genetic material in a cell is that each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA. The structures become more and more microscopic as one moves down the hierarchy.

Find the velocity of a runner who has a mass of 75 kg and 3,700 Joules of energy.
Answer:
125 joules
Explanation:
The velocity of the runner having a mass of 75 kg will be 9.93 m/s.
What is Kinetic energy of the body?
The energy of the body by virtue of its motion is called its kinetic energy.
Given is velocity of a runner who has a mass of 75 kg and 3,700 Joules of energy.
The kinetic energy of the body is given by the following formula -
KE = 1/2 mv².
Substituting the values -
3700 = 1/2 x 75 x v²
7400 = 75 x v²
v² = 7400/75
v² = 98.66
v = 9.93 m/s
Therefore, the velocity of the runner having a mass of 75 kg will be 9.93 m/s.

The ______ or _______ of matter depends on how much the particles are moving, which depends on the amount of kinetic energy the particles possess.
Answer:
Temperature or thermal energy.
Explanation:
Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.
In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.
Hence, the temperature or thermal energy of matter depends on how much the particles are moving, which depends on the amount of kinetic energy the particles possess.

Answer:
Efficiency = 71%
Explanation:
Given the following data:
Output energy = 250 Joules
Input energy = 350 Joules
To find efficiency;
[tex] Efficiency = \frac {Out-put \; energy}{In-put \; energy} * 100 [/tex]
Substituting into the equation, we have;
[tex] Efficiency = \frac {250}{350} * 100 [/tex]
[tex] Efficiency = 0.7143 * 100 [/tex]
Efficiency = 71.43 ≈ 71%
Therefore, the efficiency of the candle is 71 percent.

The information plate on a hairdrier is shown.
230 V
VSO Ha
800 W
(a) What is the power rating of the hairdrier?
Answer:
800W
Explanation:
Given the following data;
Voltage = 230 V
Model = VSO Ha
Power = 800 W
Power is calculated by the multiplication of voltage and current flowing through an electric circuit.
Mathematically, power is given by the formula;
Power = current * voltage
The S.I unit for power is Watts and it is a measure of the energy consumption of an electronic device.
An initially motionless test car is accelerated to 115 km/h in 8.58 s before striking a simulated deer. The car is in contact with the faux fawn for 0.815 s, after which the car is measured to be traveling at 60.0 km/h. What is the magnitude of the acceleration of the care before the collision? What is the magnitude of the average acceleration of the car during the collision?
Answer:
a) a = 3.72 m / s², b) a = -18.75 m / s²
Explanation:
a) Let's use kinematics to find the acceleration before the collision
v = v₀ + at
as part of rest the v₀ = 0
a = v / t
Let's reduce the magnitudes to the SI system
v = 115 km / h (1000 m / 1km) (1h / 3600s)
v = 31.94 m / s
v₂ = 60 km / h = 16.66 m / s
l
et's calculate
a = 31.94 / 8.58
a = 3.72 m / s²
b) For the operational average during the collision let's use the relationship between momentum and momentum
I = Δp
F Δt = m v_f - m v₀
F = [tex]\frac{m ( v_f - v_o)}{t}[/tex]
F = m [16.66 - 31.94] / 0.815
F = m (-18.75)
Having the force let's use Newton's second law
F = m a
-18.75 m = m a
a = -18.75 m / s²

A police car is moving east at 20m/s towards a driver who is moving west at 25m/s. The police car emits a frequency of 900Hz. What frequency is detected by the driver? The speed of sound at the time of this occurrence was 343m/s.
Answer:
f = 2445 Hz
Explanation:
i did the quiz
The frequency that the driver (observer) detects is equal to 1008 Hz
Given the following data:
Observer velocity = 25.0 m/sFrequency of sound = 900 HzSource velocity = 20.0 m/s Speed of sound = 343 m/sTo calculate the frequency that the driver (observer) detects, we would apply Doppler's effect of sound waves:
Mathematically, Doppler's effect of sound waves is given by the formula:
[tex]F_o = \frac{V \;+ \;V_o}{V\; - \;V_s} F[/tex]
Where:
V is the speed of a sound wave.F is the actual frequency of sound.[tex]V_o[/tex] is the observer velocity.[tex]V_s[/tex] is the source velocity.[tex]F_o[/tex] is the observer frequency.Substituting the given parameters into the formula, we have;
[tex]F_o = \frac{343 \;+ \;20}{343\; - \;20} \times 900\\\\F_o = \frac{363}{323} \times 900\\\\F_o = 1.12 \times 900\\\\F_o =1008 \;Hz[/tex]
Driver (observer) frequency = 1008 Hz
