A neutral atom... no matter what the element... has the same number of protons and electrons. In this case, 19 electrons are needed.
The operator should watch you wake when operating a boat near other boats when entering a congested area because it may cause personal injury or damage. The track of waves cause a disturbed flow that may affect others near the operating boat in the area.
Answer:
θ = 51.21°
Explanation:
Vh= 193.6 km/h
Va= 141.7 km/hr
Relative velocity ,Vr= 193.6 - 141.7 = 51.9 km/hr
Time taken to cover 71.3 m


t= 3.81 s
t= 0.00105 hr
So the horizontal distance x
x= Vr .t
x= 51.9 x 0.00105 km
x=0.0549 m
x= 54.96 m
Lets take angle is θ
tan θ = h/x
tan θ = 71.3/54.96
θ = 51.21°
And because of gravity it falls back down to the earth.
Contour lines of different elevations can never cross.
If they did, then the point where they cross would have
two different elevations. That's silly.
