Answer:
v = 220 m / s
Explanation:
This is a kinematics exercise, the expression for velocity is
v = 25 t² - 80 t - 200
asks the velocity for time t = 6 s.
let's calculate
v = 25 6² - 80 6 - 200
v = 220 m / s

Answer:
direction
Explanation:
because particles surround the bell, so when the bell vibrates, it causes particles surrounding it to vibrate back and forth vigorously. as these particles vibrate they collide with the neighbouring particles, passing on the energy.
hope this is what you are asking, if not please report it so that someone else gets to try it.
Electrons are negatively charged particles whereas protons are positively charged particles.
When a negative is shown on the bar, this means that the difference between the electrons and protons is a negative value, which also means that the number of electrons (negative particles) is more than the number of protons (positive particles).
Based on the above, the correct choice would be:
<span>D. There are more electrons than protons
