(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
But how did the Egyptians overcome the extreme friction of dragging such massive things through the sandy desert, some of which weighed more than 9,000 pounds? Researchers at the University of Amsterdam have come up with a very simple solution to the friction problem: they utilised water.
The pyramids were not built by slaves, contrary to common perception. Archaeologists discovered the ruins of a purpose-built town for the hundreds of labourers who constructed the renowned Giza pyramids about 4,500 years ago.
If the object, ends up with a positive charge, then it is missing electrons. if it is missing electrons, then it must have been removed form the object during the rubbing process.
Answer:
the electric charge in the Earth is -5.91 × 10⁵ C
Explanation:
Given the data in the question;
Electric field E = 131 N/C
we know that; radius of the earth r = 6,371 km = 6371000 m
and Coulomb's constant k = 8.99 × 10⁹ Nm²/c²
Now, using the following formula to calculate the charge;
E = k × Q/r²
we make Q the subject of the formula
Q = Er² / k
so we substitute
Q = [ 131 N/C × ( 6371000 m )² ] / 8.99 × 10⁹ Nm²/c²
Q = [ 5.317242971 × 10¹⁵ ] / [ 8.99 × 10⁹ ]
Q = 5.91 × 10⁵ C
Since the electric field pointing downward
Q = -5.91 × 10⁵ C
Therefore, the electric charge in the Earth is -5.91 × 10⁵ C
Answer:
<em>"Io orbits Jupiter on an elliptical orbit, due to orbital resonances with other satellites."</em>
Explanation:
- <u>"Io" moon of Jupiter:</u>
The Io is one of the four moons of Jupiter, as it rotates around the planet in an elliptical orbit, due to orbital resonance with other satellites. As due to the rotational motion of the moon, while orbiting the planet and having a large amount of gravitational pull on them there is a net amount of heat between the two heavenly bodies in the solar system. As the moon is very small in size as compared to giant celestial body, the crust of the moon is distorted by the unequal force of the gravity on each of its side by the planet causing a distortion of the moon's over all shape.
16km because she is 8km away and if she goes back it’s gonna be 8km more so it’s 16km
