If a negatively charged rod is held near a neutral metal ball, the ball is attracted to the rod. This happens:_______

Physics

Answer:

<em>c. because the rod polarizes the metal.</em>

Explanation:

Bringing the negatively charged rod close to the neutral metal ball causes the neutral metal ball to be polarized with induced positive charge on it. The polarizing of the formally neutral metal ball is due to the negative charge on the metal rod (bodies induce a charge opposite of their own charge on a nearby neutral body). The ball and rod then attract themselves because bodies with opposite charges attract each other, unlike bodies with same charges that repel each other.

kap26 [50]

Answer:

Lithium has the lowest electronegativity.

Explanation:

Electronegativity measures the tendency of an atom to attract the bonding pair of electrons. As we move left to right in a period, the number of shell remains same but the number of electron increases(negative charge increases. Hence, electronegativity also increases.

As Lithium is the left most element in this period. It has the lowest electronegativity value which is equal to 0.98.

Darlene kicks a soccer ball off the ground and in the air with an initial velocity of 34 feet per second. Using the formula H(t)
Levart [38]
At maximum height, the velocity of the ball is 0.
v = u + at
0 = 34 - 32.2t
t = 1.06 seconds

In H(t), s = 0 because the ball is initially on the ground.

H(t) = -16(1.06)² + 34(1.06)
H(t) = 18.1 feet
