Line up in a direction parallel to the magnetic field lines<span />
Answer:
Magnetism is the force exerted by magnets when they attract or repel each other.
Answer:
3 significant figures
Explanation:
here zero is counted as one of the significant figures since it lies next to an integer.
hence the number has 3 sfg
Given parameters:
Initial velocity of Coin = 0m/s
Time taken before coin hits ground = 5.7s
Unknown:
Final velocity of the coin = ?
Velocity is displacement with time. To solve this problem, we have to apply one of the equations of motion.
The fitting one of them here is shown below;
V = U + gt
where;
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity
t is the time taken
Here we use positive value of acceleration due to gravity because the coin is falling with the effect of acceleration and not against it.
Now input the parameters and solve;
V = 0 + 9.81 x 5.7
V = 55.917m/s
Therefore, the final velocity is 55.917m/s.
