Answer:
32km/hr
Explanation:
The question asks to calculate the average speed for a boat.
Mathematically, the average speed is the total distance divided by the total time
Let’s get the total distance traveled:
That would be 70km + 26km = 96km
Now the total time taken would be 3 as the boat did not move at all for an hour.
The average speed is thus 96/3 = 32km/hr
Answer: 1) p⁺ = 22; number of protons.
e⁻ = 19 - 1 = 18; number of electrons.
Net charge is +4, because atom has 4 protons more than electrons.
Proton is a subatomic particle with a positive electric charge of +1e elementary charge.
2) p⁺ = 22; number of protons.
e⁻ = 19 + 3 = 22; number of electrons.
Net charge is 0 (neutral charge), because atom has same number of protons and electrons.
Hope this helps :)
