The answer would be D , the rest are ways humans basically destroy nature
Answer:
6844.5 m/s.
Explanation:
To get the speed of the satellite, the centripetal force on it must be enough to change its direction. This therefore means that the centripetal force must be equal to the gravitational force.
Formula for centripetal force is;
F_c = mv²/r
Formula for gravitational force is:
F_g = GmM/r²
Thus;
mv²/r = GmM/r²
m is the mass of the satellite and M is mass of the earth.
Making v the subject, we have;
v = √(GM/r)
We are given;
G = 6.67 × 10^(-11) m/kg²
M = 5.97 × 10^(24) kg
r = 8500 km = 8500000
Thus;
v = √((6.67 × 10^(-11) × (5.97 × 10^(24)) /8500000) = 6844.5 m/s.

Explanation:
The question goes thus :
What happens to the charged electroscope when a conductor is moved between its plastic sheets, and why?
When a conductor is moved between its plastic sheets of a charged electroscope, the divergence between the brass plate and the gold leaf will decrease.
And why ?
Because of the unlike charges or neutral uncharged charges between the conductor and the plastic Sheets.
