The answer is A
Explanation:
Vacuuming doesn’t involve a lot of physical movements.
Answer:
J = 1800 kg-m/s
Explanation:
Given that,
Mass of a boy, m = 150 kg
Initial velocity of a boy, u = 12 m/s
Finally, it stops, v = 0
We need to find the impulse is required to produce this change in momentum. We know that impulse is equal to the change in momentum. So,
So, the impulse is equal to 1800 kg-m/s
Y, bc the height of the bounce back is higher than x
17. a sea breeze is a breeze blowing towards the land
18. a land breeze is a breeze blowing towards the sea
That's the only way you can get consistent and accurate results.
