The dirt pushing back is the 'resistance' force. It RESISTS your attempts to shovel it.
If one of the four engines suddenly fail, so this means
that we only get 3 / 4 of the original force. Since force is the product of
mass and acceleration and mass is constant, therefore we get 3 / 4 of the
original acceleration.
So the remaining acceleration is:
a = (2.0 m/s^2) * (3 / 4)
<span>a = 1.5 m/s^2</span>
Answer:
Explanation:
mass number is now 4 times less than the original value so alpha decay occur during alpha decay the mass number is decreased 4 times and atomic number decreased 2 times than the original value
I think the answer is c) 1
Hope it helps and have a good day
