Answer:
On my summer vacation, we went to the beach and we went out into the ocean the height of the wave or the amplitude they would vary. The wait or frequency between two waves was sometimes short or long but the waves had a short delay between them or wavelength
During my summer vacation, we visited the beach and ventured into the water, where the wave height or amplitude might change. Sometimes there was a little delay or a large delay between two waves, but the waves had a smaller wavelength between them.
What is wavelength?
Wavelength is the separation between the matching points of two successive waves. When two points or particles are described to be "corresponding points," it means that they are both in the same phase and have completed the same portions of their periodic motion.
Wavelength is often determined from peak to crest or from depression to trough in wave motion (waves with points oscillating at right angles to their advance direction); from compression to compression either from rarefaction to rarefaction in longitudinal waves.

Follow these steps to compare pieces of sticky tape that have the same charge:
Tear off two pieces of clear sticky tape that are about 15 cm (6 inches) long. Stick the two pieces of tape side by side on the tabletop.
Tear off two more pieces of tape, and fold under a half inch of each piece as shown in the side view. This tab makes them easy to pull off later on. Stick these pieces of tape onto the pieces already on the table and smooth them down.
tape folded to create a tab
Using both hands, grab the tabs of the two top pieces of tape. Carefully pull both top pieces of tape off the bottom pieces. Turn the non-sticky sides of the tape toward each other.
What do you observe? If there’s an interaction, explain whether the tape pieces attract or repel each other.
Answer:
they would atrract because they are sticky but when you take it off it would ware off
Explanation: I have used tape before and when you stick something to it then take it off it wares off
Two pieces of sticky tape with the same charge are formed when the non-sticky sides of the tape remain facing each other, it is observed that there is an interaction between the two pieces of tape, but the attraction and repulsion depend upon their charges.
What is the significance of attraction and repulsion?If the two pieces of tape have the same charge, they will repel each other, and as a result, the pieces of tape will move away from each other and if the two pieces of tape have opposite charges, they will attract each other, and as a result, the pieces of tape will move towards each other. The electric fields that are created by each piece of tape attract each other if they have differing in charges.
Hence, interaction between the two pieces of nonstick tape is observed, and the attraction and repulsion depend upon their charges.

What is most likely to occur during a chemical reaction
Answer/Explanation:
In a chemical reaction, the atoms and molecules produced by the reaction are called products. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
This question involves the concepts of a chemical reaction, conservation of mass, chemical bonds.
During a chemical reaction, the phenomenon that is most likely to occur from the given phenomena is "Mass is conserved".
Whenever a chemical reaction occurs old bonds between the elements are broken and new bonds are formed amongst different elements. Hence, the properties of the original substances are changed due to the formation of new bonds, and new molecules as a result.
Original molecules or substances are lost due to formation of the new ones.
No new atoms are created or destroyed in a chemical reaction. The atoms just rearrange themselves to form new molecules or substances only.
Since no atoms are created or destroyed during a chemical reaction. Hence the law of conservation of mass is applicable to a chemical reaction. This means the mass is conserved during a chemical reaction.

if the same amount of heat is added to 25.0g samples of each of the metals in the chart, which metal will experience the largest temperature change?
a. calcium
b. iron
c.silver
d.gold
Gold metal will experience the largest temperature change.
Explanation:
Given:
Four different metals of 25.0 gram in which the same amount of heat was added.
To find:
Which metal will experience the largest temperature change.
Solution
Consider heat added to all metals be Q and the mass of every metal is 25 grams. This means the value of temperature change will be dependent on value specific heat of metals.
The change in temperature of the substance when heat is supplied to the substance is given by:
[tex]Q=m\times c\times \Delta T\\\Delta T=\frac{Q}{mc}\\\Delta T\propto \frac{1}{c}....[1][/tex]
The above relation means that change in temperature is inversely proportional to the specific heat of the metal.
The specific heat of calcium =[tex]c_{Ca}=0.647 J/g^oC[/tex]
The specific heat of iron = [tex]c_{Fe}=0.449 J/g^oC[/tex]
The specific heat of silver = [tex]c_{Ag}=0.235 J/g^oC[/tex]
The specific heat of gold =[tex]c_{Au}=0.129 J/g^oC[/tex]
[tex]c_{Au}<c_{Ag}<c_{Fe}<c_{Ca}[/tex]
So, out of these metals, gold has the lowest value of specific heat and according to relation (1), the temperature change will be largest in 25.0 grams of gold and will be least in calcium.
The order of change in temperature of the metals will be:
[tex]\Delta T_{Au}>\Delta T_{Ag}>\Delta T_{Fe}>\Delta T_{Ca}[/tex]
Gold metal will experience the largest temperature change.

( please just tell me the formula to use to solve it ) A hockey puck has a coefficient of kinetic friction of μk = .10. If the puck feels a normal force (FN) of 5 N, what is the frictional force that acts on the puck?
The frictional force that acts on the puck is 0.5 N.
The given parameters;
coefficient of kinetic friction, μk = 0.1normal force of the puck, Fₙ = 5 NThe frictional force that acts on the puck is determined by taking the product of the normal force and the coefficient of kinetic friction.
The frictional force that acts on the puck is calculated as follows;
[tex]F_k = \mu_k F_n[/tex]
Substitute the given parameters in the above equation and solve the frictional force.
[tex]F_k = 0.1 \times 5\\\\F_k = 0.5 \ N[/tex]

A. the train can be heard more easily in front of the apartment complex because of reflection and interference. as the sound comes from train, the sound waves reflect off of the complex and interfere with each other increasing amplitude of the wave to make it easier.
B.the train can not be heard ad easily in the park because of reflection and diffraction. the sound reflects off of the trees in the park and diffract between the tree, this causes the waves to bend too much to be heard.
C.the train can be heard more easily in front of the apartment complex because of diffraction and refraction. the sound waves diffract between the other buildings aiming them towards the apartment complex and then the sound refracts through the apartment complex which makes it more difficult to hear in the park.
D.the train can not be heard as easily in the park because of interference and reflection. the other buildings in front of the park cause interference of the sound waves from the train and the trees in the park cause reflection making it too hard to hear the train.
