<span>Nitrogen is used to protect steel from water because nitrogen has stable physical properties that enables the nitrogen to be resistant to water molecules. Nitrogen also serves as a coat for the steel to not be corroded easily</span>
Answer:
Explanation:
Satellites experiment a force given by Newton's Gravitation Law:
where M is Earth's mass, m the satellite's mass, r the distance between their gravitational centers and G the gravitational constant.
We also know from Newton's 2nd Law that <em>F=ma, </em>so putting both together we will have:
If we are on the surface of the Earth, the acceleration would be g and 
(Earth's radius):
Which we will write as:
If we are on orbit the acceleration is centripetal (
), so we have:
And if this orbit has a radius 
we have:
Answer: Answer below hope it helps
Explanation: How does a rubber rod become negatively charged through friction? It touches a negatively charged object, and protons move off of the rod. ... It is rubbed with another object, and electrons move onto the rod. It is rubbed with another object, and protons move off of the rod.
Hello!
Recall for resistors in parallel:
We can begin by calculating the total resistance:
Now, we can calculate the current using Ohm's Law:
V = Voltage of battery (V)
i = Current (A)
R = Resistance (Ω)
Plug in the given voltage and the total resistance we solved for.
Answer:
All the meteors in a meteor shower typically come from the same comet, which is in a periodic orbit around the Sun. The dust from the comet follows the path of the parent body and as Earth intersects the debris along the comet's orbit, it plows into this material. Since the dust particles are all moving together in space before they encounter Earth, if you trace back the streak of each meteor, its path will appear to diverge from one place in the sky.
