Answer: The order is 2,1,5,4,3
Explanation: Hope This helps.
The order in which events occur in the generation and transmission of a sound wave begins with an object vibrating, which transfers energy to air particles, leading to the vibration of surrounding air and the eventual transfer of energy from particle to particle, forming a sound wave.
Sound is produced and travels through a medium via a series of events that can be listed in sequential order:
Something causes an object to vibrate.
The object's energy transfers to the surrounding air particles.
Air particles around the object begin to vibrate.
Vibrating air particles bump into other air particles.
Energy transfers outward from air particle to air particle.
For example, when a tuning fork is struck, its tines vibrate and cause air molecules nearby to oscillate. These vibrations propagate outward as successive air molecules collide, similar to ripples in water when a stone is thrown. This movement of air molecules forms a sound wave, which can be detected by the ear as changes in air pressure and interpreted as sound.

Question 1:
Answer:
Like poles repel each other. Unlike poles attract each other.
Explanation:
In a magnet their are two poles which are north pole and south pole. Like pole repel each other and unlike pole attracts each other because magnetic lines of force originate from north pole and terminate on the south pole.
Question 2:
Answer:
They would repel one another because they would both have a negative charge.
Explanation:
When balloon is rubbed with wool cloth electrons are transferred from wool to balloon. Thus, balloon acquire negative charge and wool becomes positively charged. Since, we are rubbing both balloons the charges on the surface are same. Hence they would repel one another because they would both have a negative charge.

One light-hour is the distance light travels in one hour. the speed of light is about 300,000 km/s (3 × 10^5km/s). if jupiter is 0.72 light hours from the sun, how far is this?
Answer:
Jupiter is [tex]7.776*10^8km[/tex] away from the sun.
Explanation:
The speed of light is [tex]3*10^5km/s[/tex]. This means, since there are 3600 seconds in an hour, the distance light travels in 1 hour is:
[tex]3*10^5*3600= 1.08*10^9km[/tex]
and this distance is called the light-hour.
Since Jupiter is 0.72 light-hours away from the Sun, its distance in km from the sun is:
[tex]1.08*10^8*0.72=7.7776*10^8km[/tex]
Thus, Jupiter is [tex]7.776*10^8km[/tex] away from the sun.
the image shows an electromagnet made with a 1.5-volt battery how would the magnetic field be affected if you replaced its 1.5-volt battery (on the left) with a 9-volt battery (shown on the right) while using the same nail and coil?
A. The magnetic field strength would increase
B. The magnetic field would not be affected by this change
C. The magnetic field strength would decrease
D. The magnetic field would change direction more frequently
The magnetic field strength is directly proportional to the current through the circuit. When the voltage is increased, current also increases, results in a rise in magnetic field strength. Thus, option A is correct.
What is magnetic field?A magnetic field is the field produced by the magnetic flux or field lines with a magnitude and direction. A magnetic field is always associated with an electric field where, the magnitudes of both field are in direct proportion.
The magnetic field lines will be perpendicular to the electric flux. According to Ohm's law, voltage and current through a circuit are directly proportional to each other.
As the voltage in a circuit is increased, the current through it increases which n turn result in a hike in magnetic field strength. Therefore, when 1.5 volt is changed by 9 volt battery in the circuit, magnetic field strength would increase.

what do waves transmit?
Answer:
Waves only transport a portion of energy.
Explanation:
Let's think about some examples related to waves in nature:
An electromagnetic wave is a combination of electric and magnetic fields, both of them oscillate through space and time. That oscillation transport energy, that is bounded in little "packets" of energy called photons. So this wave transmits energy.In the case of a solid, the periodic oscillation of the molecules, this kind of oscillation transport energy too and in this particular case it is called phonons. It is just a quantum of energy related to a compression wave, as a sound or a vibration lattice in a crystal.In conclusion, waves only transport a portion of energy.

Why is it inadvisable to make a horseshoe magnet from a flexible material? 1. a flexible material is not easily magnetized. 2. a flexible material is easily loses its magnetism. 3. none of these 4. the poles of the magnet attract each other and will cause the magnet to bend. 5. a flexible material cannot be easily made into a horseshoe shape?
Different magnetic poles are drawn to one another. The magnet will bend if it is too flexible, possibly allowing the poles to touch and reducing the magnetic field around it.
What horseshoe magnet from a flexible material?Since a horseshoe magnet's design naturally provides more strength than a bar magnet does, it quickly superseded the bar magnet in use. The magnet's poles are situated closer to one another and in the same plane thanks to the U-shape.
The majority of horseshoes are constructed of steel, though there are a few outliers. Because aluminum horseshoes are lighter and perform better when speed is the primary goal, racehorses typically wear them.
At the magnet's poles are concentrated its strongest elements. Because of this, a horseshoe shape is thought to be the strongest.
Therefore, particularly handy to produce if you need to carry heavy goods or strengthen a bar magnet.

Answer : Compression / Power
Explanation : In a four stroke engine, the piston compresses the gas mixture during the power / compression stroke.
In the second stage of compression stroke, the stroke begins at bottom dead center, or just at the end of the suction stroke, and ends at top dead center.
In this type of stroke, the piston usually compresses the air-fuel mixture in preparation for ignition during the power stroke.

ASAP Which of the following has kinetic energy? a. a rock poised for a fall b. an archer’s bow that is drawn back c. a rolling bowling ball d. a car waiting at a red light
The correct answer is c. a rolling bowling ball.
Explanation:The correct answer is c. a rolling bowling ball.
Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and velocity of the object. In this case, a rolling bowling ball has kinetic energy because it is moving. The other options do not involve motion and therefore do not have kinetic energy.
For example, a rock poised for a fall has only potential energy, as it does not possess motion. An archer's bow that is drawn back also has potential energy stored in the stretched bowstring, but it does not have kinetic energy until the arrow is released. A car waiting at a red light is stationary and not in motion, so it does not have kinetic energy.

An airplane flies 930 miles in 75 minutes. how many miles does it fly in 5 hours and 45 minutes assuming a constant speed?
First, calculate the average speed of the airplane, which is 12.4 miles per minute. Then, convert 5 hours and 45 minutes into minutes which is 345 minutes. Multiple the speed by this time to find the distance the airplane would fly, which is 4278 miles.
Explanation:To solve this problem, we first need to figure out the average speed of the airplane. Average speed is calculated by dividing the total distance by total time. In this case, the airplane travels 930 miles in 75 minutes. So the speed is 930 miles/75 minutes = 12.4 miles/minute.
Now that we have the speed per minute, we can calculate how many miles the airplane would travel in 5 hours and 45 minutes. This time converts to 345 minutes (since 1 hour = 60 minutes). So, the airplane would fly 12.4 miles/minute * 345 minutes = 4278 miles.

The disadvantages of solar energy primarily include its dependency on weather, need for large space, requirement of rare-earth minerals for photovoltaic cells, and potentially high costs.
Explanation:The main disadvantages of solar energy are largely tied to its dependence on weather conditions and the requirement of considerable space. Solar energy generation is chiefly affected by cloud cover, nightfall, and incident angle strike at high altitudes that influence the amount of light energy available. While solar energy conversion does not necessarily require connection to large-scale power grids, making it beneficial for remote locations, it does rely on the creation of photovoltaic cells which require rare-earth minerals that can be difficult to obtain.
