Answer: Δx = vxt = (85 m/s)(9s) = ? m
Explanation:
If the plane is in level flight,
Δx = vxt = (85 m/s)(9s) = ? m
Note that if Δx ≠ 0, it will not land on the car.
Um honestly I’m not sure but I need points but good luck god be with you mate
<span>Power and work are related by a transfer function.
This transfer function is called "Time"
</span>
<span>Power = work/ time
Power= force x distance/time
Hope this helps!!

Answer:
39.2m/s
Explanation:
Given parameters:
Mass of book = 5kg
Time taken for fall = 4s
Unknown:
Final velocity of the book = ?
Solution:
Serena dropped the book from rest therefore, the initial velocity of the book is 0.
Let us find the appropriate motion equation to solve this problem;
V = U + gt
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity = 9.8m/s²
t is the time taken
Insert the given parameters and solve;
V = 0 + 9.8 x 4 = 39.2m/s
Because plants have to use cyanobacteria during photosynthesis so they could not survive before the cyanobacteria started producing oxygen
