Answer:
A: Living systems are constantly changing,so previous explanations may no longer apply
Explanation:
Hopefully this helps!
The ideal mechanical advantage of an inclined plane or ramp is equal to the length of incline divided by height of the inclined plane. in equation
MA = L / H
since the ideal mechanical advantage of the given inclined plane is 2 and the length of inlcine is 3.8 m
MA = L / H
H = L / MA
H = 3.8 / 2
H = 1.9 m was paco above the ground
D. Gravity would make the notebook fall sooner because it is heavier.

Answer:
0.48 kgm/s
Explanation:
= mass of the particle = 2.43 μg = 2.43 x 10⁻⁶ x 10⁻³ kg = 2.43 x 10⁻⁹ kg
= velocity of the particle = 1.97 x 10⁸ m/s
= momentum of the particle
momentum of the particle is given as
inserting the values
kgm/s
