<span>Astronomers are able to determine facts about the composition of these moons by examining the nature of light that is reflected from their surfacy using a method called spectroscopy. This process works because different materials tend to reflect light at different wavelengths So, by observing at which wavelengths a planetary body reflects light, astronomers are able to estimate its composition.</span>
two or more materials mixed or stirred together. dissolve: the process of a material mixing with a liquid in a special way. ... sugar) as possible has dissolved in a liquid (such as coffee), and any additional solid material sits on the bottom.
Answer:
3: force acting on an object over time
Explanation:
The impulse formula is: change in momentum = force x time
Δp = f x t
Answer:
They have each lost the same amount of potential energy. (The lost potential energy is converted to kinetic energy.)
To calculate the velocity of the sound wave, we use this formula:
V = 331 + [0.6*T],
Where V is the velocity and T represents temperature.
When the temperature is 36 degree Celsius, we have
V = 331 + [0.6 * 36]
V = 331 + 21.6 = 352.6
Therefore, V = 352.6 m/s.
