Which statement correctly describes the main difference between body waves and surface waves?
Select one:
Surface waves are only longitudinal waves and body waves are only transverse waves.
Surface waves only travel across oceans and body waves travel across the Earth’s crust.
Surface waves are less damaging to man-made structures than body waves.
Surface waves travel across the Earth’s surface and body waves travel through the Earth’s interior.
Surface waves travel across the Earth’s surface and body waves travel through the Earth’s interior.

Thomas calculates the volume of an object by multiplying the measurements 1.74 cm x 2.3 cm x 3.09 cm. Using significant figures, how should the answer be reported?
Answer:
12 cm³
Explanation:
Always round to the place of the number with the least amount of significant figures.
1.74 and 3.09 have three significant figures. 2.3 has two significant figures. Therefore, the answer will be rounded to two significant figures.
1.74 cm × 2.3 cm × 3.09 cm = 12.36618 -> 12 cm³
(The 3 in the tenths place is less than 5 so drop it and all the numbers to the right of it.)
Hope that helps.
Plss answer the question in the picture. If you actually answer I will give you brainilest!!!
Answer:
hey :)
your answer is D.
Explanation:
To find density, you must divide mass and volume.
8 divided by 4 is 2
6 divided by 6 is 0
4 divided by 2 is 2

Why do you think the different heating process result in different softness or hardness of the steel? Think about what steel is made of and how the atoms move .
Explanation:
Different heating process affect the microstructure of the steel in different ways. Thus, imparting different properties to the steel. For example, annealing is done is done to impart softness to steel, hardening is done to hardened the steel( eg: carburizing, nitriding, cyaniding) whereas tempering is done to improve the ductility of the steel.
Steel mainly contains iron and carbon. This percentage of carbon and iron decides the property of the steel. It is the % of carbon which is altered in different heating process that to obtained the desire microstructure in steel.

Two cars travel next to each other. One speedometer reads
20 meters per second and the other reads 72 kilometers per
hour. If arrows represent speed, which pair of arrows
represents the relationship of speeds of these two cars?
The blue arrow is always the 20 meters per second car.
PLEASE HELP
Answer:
The pair of arrows which represents the relationship of speeds of the two cars is;
The second option as shown in the attached drawing
Explanation:
The given parameters are;
The reading on the speedometer of one car = 20 m/s
The reading on the speedometer of the other car = 72 km/h = 20 m/s
The blue arrow = 20 m/s
Therefore, given that the speeds of both cars are equal (20 m/s = 72 km/h = 20 m/s), the pair of arrows that represent the relationship of speeds of the two cars is two equal length blue arrows which is the second option
The attached diagram showing the pair of arrows that represents the relationship of speeds of the two cars is drawn using Microsoft Visio.

How many moles are in 54 grams of C?
How are sodium (Na) and potassium (K) similar?
A. They rarely react.
B. They are highly reactive.
C. They are hard metals.
D. They are soft nonmetals.
Answer:
B. They are highly reactive.
Explanation:
Answer:
B: They are highly reactive
Explanation:
Sodium(Na) and potassium(K) are in the same family/group which is the Alkali Metal group. These groups have their ability to displace H2(g) from water and create a basic solution. Alkali metals are also known to react violently and explosively with water. This is because enough heat is given off during the exothermic reaction to ignite the H2(g). Therefore, they are similar because of their reactivity.

Large amounts of an unknown compound were isolated from seawater. The compound contained 32.0 grams ofbromine and 4.9 grams of magnesium. What is its percent composition?
Answer:
87% bromine and 13% magnesium
Explanation:
The compound contained 32.0 grams of bromine and 4.9 grams of magnesium.
We need to find its percent composition.
Mass of the sample = mass of bromine + mass of magnesium
= 32 g + 4.9 g
= 36.9 g
Percentage composition of bromine,
[tex]\%=\dfrac{32}{36.9}\times 100\\\\=86.7\\\\=87\%[/tex]
The percentage composition of magnesium,
[tex]\%=\dfrac{4.9}{36.9}\times 100\\\\=13.27\\\\=13\%[/tex]
So, its percent composition is 87% bromine and 13% magnesium.

Which element has the largest atom (longest atomic radius) and which element has the smallest atom (shortest atomic radius)?
Answer:
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
