Boron, Aluminum, Gallium, Indium, Thallium
Answer:
option D is correct
Explanation:
cl has 17 electrons if it has 18 it becomes cl-
1 is 0n I believe 2 8n or 2n 3 would be 10n 4 is 0n or 12n
Speed x time = distance
Distance divided by time = speed
500 divided by 5
Speed = 100
ThIs is the same type of problem
find out the time value
3 = 1/2*a*T^2
6/10 = t^2
t = 0.77 seconds
and the distance is given 5 m
thus speed ,= distance/time
speed = 5/0.77
= 6.45 m/s
