Answer:
750 force
Explanation:
I have never worked with force but I can guess using the formula. 1500, which is the mass, multiplied by the acceleration, 0.5, would equal 750 force, if being applied by the equation listed, Force= mass×acceleration

a studentistrying to design an artifical eardrum fo their science fair project. they made their eardrum hollow to cut down oncost and weight. when they tested howlong it took to test the subject tohear deep, they found that their control ear drum made outof wood did better than their created one. the temperature that day wa 98 fahrenheit.
determine which statement supports the students findings.
a.the created eardrum performed worst because sound travels faster in solids due to large distance between the particals
b. the created eardrum performed worst because sound travels faster in solids due to the small distance between the particles.
c.the created eardrum performed worst because sound travels slower in air due to the small distance between the particles.
d.the created eardrum performed worst because sound travels slower through air in high temperatures due to the particles moving slower.

a.

based on the table and your knowledge about waves, what can you conclude about the wavelength of mechanical waves compared to electromagnetic waves?
A. Mechanical waves have greater amplitude
B. Mechanical waves tend to have longer wavelength
C. Mechanical waves tend to have shorter wavelength
D. Mechanical waves travel faster than electromagnetic waves
(please be certain about your answer)
Answer:
The correct answer is option B) Mechanical waves tend to have longer wavelengths.
Explanation:
Before we begin, let's clarify what these two types of waves are.
Both electromagnetic waves and mechanical waves are classified by their ability to transmit energy in empty space.
Electromagnetic waves are capable of doing that, but mechanical waves are not.
The light waves that reach our planet are an example of electromagnetic waves.
On the other hand, mechanical waves need a medium to be able to move energy, it is not the same as with electromagnetic waves that are capable of transporting it on their own.
An example of a mechanical wave is sound. Sound is not capable of traveling in empty space.
This leads us to the conclusion that Mechanical waves tend to have longer wavelengths.
A column is filled with four different liquids of different densities. A red liquid, a blue liquid, a green liquid, and a purple liquid are all added into the column. This chart shows the densities of the liquids.
A 2-column table with 4 rows titled densities of liquids. The first column titled Liquids has entries red, blue, green, purple The second column has entries 1.2 grams per centimeter cubed, 1.6 grams per centimeter cubed, 0.8 grams per centimeter cubed, 0.1 grams per centimeter cubed.
In what order would the liquids would arrange themselves, from top to bottom?
blue, red, purple, green.
purple, green, red, blue.
purple, green, blue, red.
blue, red, green, purple.
Answer:
purple, green, water, red, blue
