Answer:
Explanation:
None of the other answers matter but the right answer which A. Silicon has an outer shell of 4. Carbon can connect with 4 elements because of its outer shell. CH4 is the simplest example. But C2H6 is also possible.
H H
H - C - C - H
H H
There are 4 connections to the outside world for the Carbon (C) on the left.
It has 3 hydrogens connected on to it and one of its connecting electrons goes with the other carbon on the right.
Silicon can do the same thing.
Answer:
250 m
Explanation:
Given :
Initial velocity, u = 0
Acceleration, a = 5 m/s2
Time elapsed is t = 10 seconds
The distance traveled in 10 seconds by the particle when accelerating at 5 m/s2 is given by,

Putting the values,


x = 250 m
The particle moved 250 m in 10 seconds
I think the correct answer from the choices listed above is option D. A bolt of lightning is caused by e<span>lectrical charges building up in the space between the clouds and the ground. Hope this answers the question. Have a nice day.</span>
It's cyan. I believe it's because it has green and blue in it.
Explanation:
Momentum is conserved.
a) In the first scenario, Olaf and the ball have the same final velocity.
mu = (M + m) v
(0.400 kg) (10.9 m/s) = (70.2 kg + 0.400 kg) v
v = 0.0618 m/s
b) In the second scenario, the ball has a final velocity of 8.10 m/s in the opposite direction.
mu = mv + MV
(0.400 kg) (10.9 m/s) = (0.400 kg) (-8.10 m/s) + (70.2 kg) v
v = 0.108 m/s
