Describe what happens to you if you are riding a skateboard and the board hits something (like a curb) with the front wheels. Which law does this apply to?
Answer:
First law of motion because your body will keep moving forward and fly off your skateboard since the curb only stops the board, not yourself.
Volcanos are a geologic phenomenon that occurs at tectonic plate boundaries.Which provides the best evidence for the theory that faults and volcanoes are results of tectonic plate interactions?
a. Faults on tectonic plates are in constant motion, but volcanoes may not erupt for many
years
b. Tectonic plates that have many faults do not usually have volcanoes.
a. Faults and volcanoes existed long before there were tectonic plates.
b. Faults and volcanoes are often found at tectonic plate boundaries.

C: bounce off of a material
D: interact with different types of materials
If you use the same force to push a motorcycle as you would to push a bike, which one will have more acceleration and why? Explain using Newton’s Second Law
Answer:
the bike would because it has less mass.

The picture below shows an experiment to find out the highest frequencies which students can hear. When the teacher turns the dial the frequency from the loudspeaker increases. the students put their hands down when they can no longer hear the sound.
Some students put their hands up while others have put their hands down. What conclusion can you draw from this observation?
The teacher suspects that some of the students are not giving honest responses, they are keeping their hands up even when they can no longer hear the sound. How could he check if he is right? *
Answer: Different hearing abilities.
Explanation:
From the observation, it can be concluded that different students have different hearing abilities. Some students put their hands up later, indicating that they can hear higher frequencies, while others put their hands down earlier, indicating that they can only hear lower frequencies.
To check if the teacher's suspicion about some students not giving honest responses is correct, he could randomly select some students and ask them to identify a few frequencies. He could also use different methods to test their hearing abilities, such as using headphones or playing the sound at different volumes to see if they can still hear it. Additionally, the teacher could repeat the experiment on different days to check if the same students are consistently putting their hands up even when they cannot hear the sound.
A cylindrical tube of length 27.75 cm and radius 2.00 cm is filled with argon gas. The empty tube weighs 188.25 g. The tube filled with argon weighs 188.87 g. Calculate the density. formula =
Answer:
Explanation:
that should help
Density is mass per unit of volume. The density of argon is 1.778 × 10⁻³ gm/cm³.
How are the density, volume, and mass of a substance related?Suppose that a finite amount of substance is there having its properties as:
mass of substance = m kgdensity of substance = d kg/m³the volume of that substance = v m³Then, they are related as:
d = m/v
The volume of the tube = π × r² × h
= π × (2cm)² × 27.75 cm
= 348.716 cm³
Mass of Argon = Mass when tube is filled - Mass when tube is empty
= 188.87 g - 188.25 g
= 0.62 g
Now, the density of the gas can be written as,
Density = Mass / Volume
= 0.62g / 348.716 cm³
= 1.778 × 10⁻³ gm/cm³
Hence, the density of argon is 1.778 × 10⁻³ gm/cm³.
