No, light does not have mass because a photon does not way anything.
Wow I have no idea kid............
Let's look at the density of water at 25 deg C and compare that to a higher temperature, 80 deg C. The density decreases from 0.9970 g/mL to 0.9718 as it is heated. This makes sense because, as heat is added to the liquid water, there is greater kinetic energy of the molecules and there are also more vibrations of the water molecules. Together these mean that each H2O unit in liquid water takes up more space as the temperature increases.
Answer:
7.3 newtons to the west
Explanation:
3.7kg × 11a - 3.7kg × ? = 3.7n
Answer:
Explanation:
As per the spectrum range, it is important to observe the Sun and other astronomical objects from Earth's surface because they lie in the visible band of spectrum.
Earth's atmosphere absorbs ultraviolet light coming from the space thus helps us to know and learn about their properties.
If we place telescope in space, would be covered with water droplets thus making it useless to study about any object or to see them hence proper place such as Earth's atmosphere is well suited to observe stars and other celestial bodies.
