Answer: Protons give the nucleus a positive charge.
Explanation:
Protons - Gives of positive charge
Neutrons - Gives of neutral charge (No charge)
Electrons - Gives off negitive charge
Answer:
When a ball thrown upward reaches its highest point, its velocity is? is still -9.8 m/s2. The acceleration due to gravity is always -9.8 m/s/s, regardless of the ball's velocity.
Answer:
Explanation:
Average acceleration is defined as the change on velocity on an interval of time:
with Vf the final velocity, Vi the initial velocity and t the time interval. Note that the initial velocity is positive because is in the positive x direction and final velocity is negative because is in the opposite direction, so:
The negative sign indicates that the acceleration is in the negative x direction.
Answer:
They will go backwards?
Explanation:
If positive they go forward but is negative they go backwards.
