In a sound wave, the magnitude of the compression is ___ the magnitude of the rarefaction.
equal to
is used to send radio signals
protects the earth from UV radiation
is made of charged ions and free electrons
Answer:
Buzz Aldrin
Neil Armstrong
John Glenn
Yes, John Glenn was the first to orbit the earth but the question I read was who WALKED ON THE MOON.....the answer to who was the FIRST to walk on the moon... is Neil Armstrong but Buzz Aldrin also walked and was there with Armstrong but wasn't the first. You have to be careful about the astronaut 'firsts'. Alan Shepherd was the first in space....John Glenn was the first to orbit the earth....Edward White was the first to 'walk in space' and Neil Armstrong was the first man to walk on the moon. Also remember that all of these were American Astronaut firsts. The Russians actually put up the first man in space. Yuri Gagarin was the first man. Buzz Aldrin landed and walked on the moon also.

Answer:
The answer is A
Explanation:
b. What is the magnitude of the tension in the string at the top of the circle if you are swinging it at 3.55 m/s?
c. What is the magnitude of the tension in the string at the bottom of the circle if you are swinging it at 3.37 m/s?
b. its melting point
c. its amount of heat transferred
d. its rate of change in temperature
The following that is is most closely related to the specific heat of a substance is its rate of change in temperature. The answer is letter D. The amount of energy required to raise the temperature of 1 kilogram of a substance by 1 Kelvin is called the specific heat. The answer is a. For example, water. Water has a specific heat of 4.18 Joules per kilogram per Kelvin. This means that in order for water to change from one state to the other at one kelvin, it needs 4.18 Joules of energy per one kilogram of water. But it does not apply to changes in phase, because the heat added or removed during a phase change does not change the temperature of a substance.
