Answer:
v = 120 m/s
Explanation:
We are given;
earth's radius; r = 6.37 × 10^(6) m
Angular speed; ω = 2π/(24 × 3600) = 7.27 × 10^(-5) rad/s
Now, we want to find the speed of a point on the earth's surface located at 3/4 of the length of the arc between the equator and the pole, measured from equator.
The angle will be;
θ = ¾ × 90
θ = 67.5
¾ is multiplied by 90° because the angular distance from the pole is 90 degrees.
The speed of a point on the earth's surface located at 3/4 of the length of the arc between the equator and the pole, measured from equator will be:
v = r(cos θ) × ω
v = 6.37 × 10^(6) × cos 67.5 × 7.27 × 10^(-5)
v = 117.22 m/s
Approximation to 2 sig. figures gives;
v = 120 m/s
Answer:
There would be tremendous earthquakes and tsunamis, followed by massive volcanism around the impact zone. The ozone layer would be destroyed. The oceans would turn acidic. The Sun would be blotted out, probably for decades.

Electric Charge Conserved means that no case has ever been found.
Explanation:
- The electric power can neither be built nor destroyed.
- But it can be saved and used whenever required, the closed-circuit system is movement of charges tends to current, which means the flow of charge, but the charges are still existing in the closed system, the charges in the isolated does not changes and it is always filled with charges, only on power trigger the charges moves.
- Found in material like copper, iron, etc.
- This is based on the rule of conservation of power that defines that, power can neither be built nor it can be destroyed, but it can be transformed into one order to another order.
- Hence this case is found in all electrical circuits.
- This fails in nonconductors like wooden, glass and plastic with no flow of charges in them.
Answer:
Your answer is A.) 5 Billion years...
Explanation:
Earth has been in it's current area for 4.54 billion years and 4.54 rounded out to a whole number is 5, so it's 5 billion years....
Hope this helps you!!
