Answer:
a. What is the wavelength?
The wavelength is 5 meters.
b. What is the frequency?
The frequency is 0.05Hz
c. What is the wave velocity?
The wave velocity is 0.25 meters per second
Explanation:
the wavelength is the distance between two troughs or two crests, which in this case is 5 meters.
the frequency=cycles/time. For this equation the equation would be 1/20, which is 0.05
the wave velocity=wavelength x frequency. Plug in the numbers, 5 x 0.05, and you will get 0.25.
Answer: The volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Answer:
Carbon-14 or C-14
Explanation:
Since the isotope is a carbon isotope, it means the the atomic number of the isotope is 6.
The atomic number of an element is the proton number.
Therefore, the isotope has a proton number of 6
Now we need to obtain the mass number of isotope in order to write the symbol of the isotope. This is illustrated below:
Mass number = Proton +Neutron
Proton = 6
Neutron = 8
Mass number = 6 + 8
Mass number = 14
Therefore, the symbol of the isotope is carbon-14 or C-14
This is a biology question. Cyanobacteria partake in photsynthesis, meaning they take in carbon dioxide and water to produce glucose and oxygen.
