Answer:
oxygen
Explanation:
plants convert carbon dioxide into oxygen for animals to breathe in return we give the plants carbon dioxide.
Mr. spoke is travelling with speed v = 9.4c.
Mr. spoke is apparently unknowing of theory of special relativity by Einstein. The theory states that moving clock tick slower than stationery clock.
Time elapse =∆t = 3 weeks
(In earth stationery frame)
Time ellipse= ∆t' = 1 week
(In the frame of rocket)
∆t' = ∆t'/γ
1/y² = 1 - v²/c²
∆t'²/∆t² =
=1²/3²
=1/9
c= 3×10⁸m/s
on solving above equation we get :
v = 9.4c
He was spreading around at close to the speed of light.
Experience significant time dilatation.
He is travelling with speed v = 9.4c.

# SPJ4
The answer is <span>C. 49 m/s
The kinetic equation is:
v2 = v1 + a * t
v1 - initial velocity
v2 - final velocity
a - gravitational acceleration
t - time
We know:
v2 = ?
v1 = 0 (in free fall
a = 9.8 m/s
t = 5
</span>v2 = v1 + a * t
v2 = 0 + 9.8 * 5
v2 = 0 + 49
v2 = 49 m/s
M = mass of the larger fish =5kg
<span>V = velocity of the larger fish =10m/s</span>
<span>m = mass of the smaller fish =2kg</span>
<span>v = velocity of the smaller fish =10m/s
</span>formula=
<span>MV = mv
5kg*10m/s=2kg*10m/s
biggern mass fish has more momentum
hope this helps
