Increasing ; moving away
This indicates the light's wavelengths are (increasing) and the star or galaxy is (moving away.)
The colors of light emitted from heated atoms had very specific energies.
The correct answer would be D. In an isolated system, the total amount of matter is conserved. This is in agreement with the law of conservation of mass where mass cannot be created or destroyed, what goes inside the process should be the same amount as what goes out the process.
Answer:
f = 2 Hz
Explanation:
The frequency of a wave is defined as the no. of waves passing per unit of time. Therefore, the frequency of a wave can be calculated by the following formula:
where,
f = frequency of the wave = ?
t = time passed = 1 s
n = no. of waves passing in time t = 2
Therefore,
<u>f = 2 Hz</u>
They are not two different temperatures. They are two different
descriptions of the same temperature, using different-size degrees
and different scales. A lot like "60 miles per hour" and "96.6 kilometers
per hour" ... the same speed.
In the case of the temperatures, the tags " °F " and " °C " show that the
units are different. And even though it's not obvious from the descriptions,
they also start counting at different temperatures.
