Answer:
Suck up the iron using the electromagnet.
Explanation:
Iron is magnetic and copper is not. So copper will be
unaffected by the magnet. After extracting the iron,
open the switch. The electromagnet will lose its
magnetism and the iron fillings will fall off..
<u>Answer</u>
3.44 m/s
<u>Explanation</u>
The motion apply the equations of Newton's law of motion. The ball is acceleration is -9.8 m/s² (acceleration due to gravity. It is negative because the ball is going against gravity, so it is decelerating).
The first equation of Newton's law of motion is;
V = U + at
Where V is the final velocity, U is the initial velocity, a is acceleration and t the time taken.
V = 25 + (-9.8 × 2.2)
= 25 - 21.56
= 3.44 m/s
Oh ya the correct answer for this is B I think because structure B
