Answer:
D. Vectors are quantities described by both magnitude and direction.
Explanation
Answer:
The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2
Explanation:
The force of friction and the kinetic force make the law of mass in moving so
The forces are the same however at the moment to determinate the acceleration
are constant because they make the same motion however the difference of mass make the acceleration difference
If the ball is made of any magnetic metals (Iron, Nickel, Cobalt) It's 3.
But if it's made of something else without any magnetic force it's 2.
