Which describes why people on earth can see light from the stars in the sky that are so far away? A.
Light from the stars is visible light and travels in longitudinal waves. Longitudinal waves require a medium to travel; therefore, light is reflected off particles of matter in space to be seen on the earth.

B.
Light from the stars is visible light and travels as surface to surface waves. Surface waves require a medium to travel; therefore, light travels from the surface of the star to the surface of the earth.

C.
Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves require a medium to travel; therefore, light is reflected off particles of matter in space to be seen on the earth.

D.
Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves do not require a medium to travel; therefore, light travels through the vacuum of space to be seen on the earth.

Which is true about carbon-12 compared with carbon-13

Answers

e mass number of any given atom depends solely on the number of protons and neutrons in its nucleus. The mass number of any atom can be determined by adding the number of protons and neutrons. (Mathematically this is stated as Mass Number = Protons + Neutrons). For instance, a Carbon atom with 6 protons and 6 neutrons will have a mass number of 12AMU. However, a Carbon atom with 6 protons and 8 Neutrons will have a mass number of 14AMU. They are both Carbon atoms, however they each have a different mass number. Atoms of the same element that have different numbers of neutrons, and therefore, different mass numbers, are called isotopes. Isotopic symbols are used to indicate isotopes of the same elements. In the following isotopic symbols the lower number is the atomic number…it is the number of protons. The upper number is the mass number, it represents to sum of the protons and neutrons in the atoms nucleus.

You have trained all year for a marathon. In your first attempt to run a marathon, you decide that you want to complete this 26-mile race in 4.5 hours.What would your average speed have to be to complete the race in 4.5 hours? Give you answer in kilometers per hour.

Answers

To complete the marathon of 26 miles in 4.5 hours, the average speed required is 9.3 kilometers per hour.

What is average speed?

To find the average speed required to complete a marathon of 26 miles in 4.5 hours, we can use the formula:

average speed = total distance / total time

The total distance of the marathon is 26 miles, which is equivalent to 41.84 kilometers (1 mile is approximately 1.60934 kilometers).

The total time we want to complete the marathon in is 4.5 hours, which is equivalent to 4.5 × 60 = 270 minutes.

Converting the units of distance and time to kilometers and minutes respectively, we have:

average speed = 41.84 km / 270 min

Simplifying this expression, we get:

average speed = 0.155 km/min

To convert the units to kilometers per hour, we can multiply by 60, since there are 60 minutes in an hour:

average speed = 0.155 km/min × 60 min/h = 9.3 km/h

26 miles is roughly 41.84 kilometers. So all we have to do is put 41.84 over the time.

41.84/4.5

9.298 km/hr
