force= mass x acceleration= 0.2 x 20= 4 N
(N stands for newton btw)
7(a) transpiration is faster in warmer dry air
(b)(I)xylem
(ii) 1. They are stacked end-to-end
2. Consists of dead cells
Answer:
The object will continue moving at 5 mph ( b )
Explanation:
For an object moving at a constant speed, the forces acting on it cancels each other out, or there are no external forces atall. hence its net force = 0 N . so the true statement is that the object will continue moving at its constant speed of 5 mph because its net force = 0 N
