B. The apple from the bottom will hit the ground earlier. This is because an increase in height causes an increase in the time that the object will fall, and therefore will affect the final velocity of the falling object. Moreover, the reduction in velocity due to friction from the air should also be considered.
Answer:
Plasma
Explanation:
A Coronal Mass Ejection (CME) is an outburst of energy that occurs near the outer part of the sun's atmosphere which causes a production of plasma along with a magnetic field.
The outermost part of the sun's atmosphere is called the Solar Corona Although difficult to see, the corona can be seen during a total solar eclipse.
Plasma from CME are clouds of magnetized electrically charged particles which the solar wind causes to travel at a speed of 1.6 million km/hr.
Answer:
Explanation:
Plastic or rubber are regarded as an insulator, and an insulator does not allow the flow of electric current through them, so the handles of screwdrivers as well as pliers that electricians use in repairing is been covered with plastic or rubber so that electric current is prevented to pass through it to the body of electricians to avoid been electrocuted as well as shock.
Answer:
Average velocity of the girl is 1.25 m/s.
Explanation:
Answer:

Explanation:
This is an exercise where you need to use the concepts of <em>free fall objects</em>
Our <u>knowable variables</u> are initial high, initial velocity and the acceleration due to gravity:



At the end of the motion, the <u><em>rock hits the ground</em></u> making the final high y=0m

If we <em>evaluate the equation</em>:

This is a classic form of <u><em>Quadratic Formula</em></u>, we can solve it using:




Since the <u><em>time can not be negative</em></u>, the <em>reasonable answer</em> is
