Answer: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.
Answer:
It has the least potential energy at the bottom of its circular path.
Explanation:
It has the least potential energy at the bottom of its circular path.
Remember the equation
U = m*g*h
where U is the potential energy
m is the mass of the yo-yo
h is the height
P1v1/t1 = p2v2/t2
p1=475, v1=4, t1=290
v2=6.5, t2=277
solve for p2 in kpa
