Answer:
C. The net force applied to the ball is zero.
Explanation:
From Newton's second law of motion;
F = ma
Where F is the force on an object, m is its mass and a is its acceleration.
Therefore, the force on an object is a product of its mass and acceleration as it travel from one point to another.
Since acceleration relates to the rate of change in velocity to time. Then when the object moves at uniform velocity (especially along a straight path), its acceleration is zero.
So that;
F = m x 0
= 0
No force is applied on the object.
Therefore for the ball in the given question, the net force applied to the ball is zero because it rolls with constant speed along a straight path.
Answer:
Hmmm...It should be B.
Explanation:
You can't just assume you have depression just because of one day of sadness. You have to wait until you get more...factors or "symptoms", if so, you shouldn't diagnose yourself until you can confirm it by a mental health doctor (Not sure what it's called) or therapist.
××× If it's not B, I sincerely apologize! ×××

transparent tool containing two curved surfaces used to refract images – either
converge or diverge. Mirrors on the other
hand, show what the real image is without distortion.</span>
