Answer:
The velocity 
of the cart with respect to the ground is
if we consider North the positive y-direction and East the positive x-direction.
Explanation:
We have for relative motion the following expression:
Where is the velocity of the cart with respect to the ground, 
is the velocity of the cart with respect to the plane and 
is the velocity of the plane with respect to the ground.
We find that:
Thus:
Answer:
(5g/cm³)*(10cm³) = 50g
Explanation:
This is just a conversion formula. Easy to find using dimensional analysis.
(5g/cm³)*(10cm³) = 50g
Answer:
Natural selection is a mechanism, or cause, of evolution.
Explanation:
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
According to my research I found questions with the same info with option choices and they are:
