Answer:
1.Oxidation - reduction reactions and proton pumping
2. Phosphorylation reactions and proton pumping
Explanation:
In oxidative phosphorylation, electrons are transferred from donors to acceptors, that is redox reaction.
These redox reactions release energy, which is used to form ATP. In eukaryotes, these redox reactions are carried out by protein complexes within cell's mitochondria, whereas, in prokaryotes, these proteins are located in the cells' intermembrane space. These linked sets of proteins are called electron transport chains.
let the ron and hermoine apply force along the horizontal direction . let ron pulls in left direction. and hermoine pulls towards right
lets assume that the left direction is taken as negative and right direction as positive.
F = force applied by ron towards left
F' = force applied by hermoine towards right
a = acceleration of the book
m = mass of book
force equation for the book is given as
- F + F' = ma
Given that : F = F'
hence
- F' + F' = ma
0 = ma
a = 0 m/s²
since the book was initially at rest and the acceleration comes out to be zero, hence the book will not move.
so correct choice is
D) The book will not move
The time of fly of a projectile to the same level as it was launched is 2(v_y)/g=2(47sin(25))/g. We multiply this by the v_x to get the distance. Thus, the distance is <span>2(47sin(25))/g*47cos(25)=86.2. This is a overshoot!</span>
Answer:
1)49m/s
2)122.5m
Explanation:
The expression below can be use to calculate the initial velocity from law of motion
V2 - V1= at
Where V2= final velocity
V1= initial velocity( from rest)
a=acceleration
t= time= 5 seconds
But V2=0
V1=gt
Where g= acceleration due to gravity= 9.8m/s^2
V1= 9.8×5
V1=49m/s
Then we can now calculate the maximum height the rocket reaches by using below formula
V^2=2gh
h(max)=v^2/2g
Where h= maximum height
V2= initial velocity
=49^2/(2×9.8)
=2401/19.6
=122.5m
Hence the maximum height it reaches vis 122.5m
