The data shows the speed of sound through air and water from the sea at 21°C. How does the speed of sound compare in sea water to the speed of sound in air? (1 point)
The speed of sound is slower in sea water because the molecules in sea water are closer to each other and less dense.
The speed of sound is faster in sea water because the molecules in sea water are farther from each other and less dense.
The speed of sound is slower in sea water because the molecules in sea water are farther from each other and more dense.
The speed of sound is faster in sea water because the molecules in sea water are closer to each other and more dense.
The speed of sound is faster in sea water because the molecules in sea water are closer to each other and more dense.
A student does an experiment to find out how the speed of sound waves changes when traveling in different mediums (solid, liquid, gas). The table below shows the different speeds of the sound wave in each medium but does not list the specific medium. The student knows that sound travels through room temperature air at 343 m/s. Using this information and the student's results, which medium is the solid, the liquid, and the gas? (1 point)
A is the liquid, B is the gas, and C is the solid.
A is the gas, B is the solid, and C is the liquid.
A is the gas, B is the liquid, and C is the solid.
A is the solid, B is the liquid, and C is the gas.
Based on the given information, A is the gas, B is the liquid, and C is the solid.
Why would we see a golf ball flying through the air before we hear the noise of the golf club hitting the ball?(1 point)
because only light must travel through matter to be seen
because sound travels slower through air compared to light
because sound travels faster through air compared to light
because light and sound travel at the same speed through air
Because sound travels slower through air compared to light.
How can we make a ray of light bend toward the normal?(1 point)
We can make it travel through glass
We can make it travel through water
We can make it travel from glass into air
We can make it travel from air into glass
We can make a ray of light bend toward the normal by making it travel from air into glass.
What happens when light waves travel from air through a solid?(1 point)
The light waves will move in a straight line.
The light waves will move in a straight line.
The light waves will move in a zigzag line.
The light waves will move in a zigzag line.
The light waves will speed up in the solid medium and bend.
The light waves will speed up in the solid medium and bend.
The light waves will slow down in the solid medium and bend.
