2 valence electrons
Explanation:
Electron configuration of nickel (Ni):
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁸
The valence electrons are in the electronic shell with the higher principal quantum number (n). In our case, nickel have 2 electrons in the 4s², with the n = 4.

Answer:
Explanation:
Impulse results in change of momentum
FΔt = mΔv
F = 0.030(50.0 - 0) / 0.010 = 150 N
The vertical portion of that force adds to his weight on the ice
Fmax = 60.00(9.81) + 150sin30 = 663.6 N
As this is above the ice strength, He takes a cold dip.
Answer: Graphite and iodine are non-metals that have lustre.
Explanation:
Graphite is a non-metal which has metallic luster. Metallic lustre is due to presence of free electrons in them, generally non metals don't exhibit this property, but iodine and graphite are non metals they exhibit metallic lustre.
PART A)
Equivalent resistance in series is given as
now we have
PART B)
Here in order to find the current in the circuit we can use ohm's law
here we have
V = 24 Volts
R = 23 ohm
PART C)
Now in series circuit all branches of resistance connected to each other
so here no division of current
hence current in all resistors will be same
so we have
Answer:
If you threw a baseball at the speed of light, the ball would move 299,792,458 kilometers per second. Unlike light, a baseball has mass as it approaches the speed of light, its mass would increase towards infinity. As nothing can go faster than the speed of light, it is known as the speed limit of the universe.
