Answer:
419.25 lbs
Explanation:
Let iron density be 491.5 lb/ft3
and aluminum density be 169 lb/ft3
We can calculate the mass of iron that displaces 1.3ft3
Also the mass of aluminum that displaces 1.3 ft3
So by using aluminum, the airplane can save
638.95 - 219.7 = 419.25 lbs of weight
Answer: 1.04N
Explanation:
Given
q1 = 2*10^-6C
q2 = 3.6*10^-6C
r = 0.25m
k = 9*10^9
Magnitude of electrostatic force can be calculated by using coulomb's law. Coulomb's law states that, "the magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them."
F =(kq1q2) / r²
F = (9*10^9 * 2*10^-6 * 3.6*10^-6) / 0.25²
F = 0.0648/0.0625
F = 1.04N
The type of electrostatic force between the charges is the repulsive force
Hello, I don't see a table, but I am guessing that you are referring to the one I attached (below).
Answer:
So, the correct order of events sorted chronologically is:
<u>
1. A nebula located in the Milky Way galaxy begins pulling nearby hydrogen atoms in its orbit.
</u>
2. The Nebula shrinks in its volume due to gravity, becoming denser and hotter. But, it's not hot enough for nuclear fusion.
<u>
3. The temperature in the core of the Nebula reaches 14 million Kelvin.
</u>
4. Hydrogen atoms begin shedding their electrons and colliding with one another.
5. The Sun enters the main sequence stage. The energy created as a result of its radiation begins nurturing life on planet such as Earth.
6. The Sun uses up all the hydrogen in its core.
<u>
7. The Sun expands greatly and cools. It is larger and redder.
</u>
8. The Sun completely runs out of hydrogen to fuse. Its outer layers are pushed away, and a cloud of ionized gas surrounds its core.
<u>
9. The Sun is a white dwarf with a dim glow.</u>
Hope this helps!
