Answer:
your problem is it's side ways flip it having the people heads pointing up no kkk
To find the height of the cliff
use the kinematical equation
height = 1/2*a*t^2
= 5*0.75*0.75 = 2.8125 m
Answer:
60 m
Explanation:
Arthur and Betty will be walking for the same amount of time t
Speed of Arthur = 3 m/s
Speed of Betty = 2 m/s
Distance = Speed × time
Distance covered by Arthur = 3t
Distance covered by Betty = 2t
Distance that Arthur and Betty will cover will be 100 m
3t+2t = 100
⇒5t = 100
⇒t = 100/5
⇒t = 20 s
So, Arthur and Betty will be walking for 20 seconds
Spot is by Arthur's side and keeps running in between them until they meet. So, Spot will be running for 20 seconds and the displacement covered will be the distance covered by Arthur which is
3t = 3×20 = 60m
Displacement is the shortest distance between two points so, Spot's displacement will be 60 m
Answer:
D) biophysics.
Explanation:
Hello,
In this case, since biophysics is the study of physical processes and phenomena happening in living things at molecular scale, which includes cells, tissues and organisms. Both experimental and theoretical techniques are used in order to understand biological and biochemical behaviors inside and outside the cells.
Best regards.
