The other options all directly affect algal bloom production because they affect the nutrients in the water, and an overabundance of certain nutrients in the water is what causes algal bloom.
Explanation:
It is given that,
Height, h = 3.1 m
Initial speed of the rocket, u = 0
Final speed of the rocket, v = 28 m/s
(b) Let a is the acceleration of the rocket. Using the formula as :
(a) Let t is the time taken to reach by the rocket to reach to a height of h. So,
t = 0.22 seconds
(c) At t = 0.1 seconds, height of the rocket is given by :
h = 0.63 meters
(d) Let v' is the speed of the rocket 0.10 s after launch.
So,
v' = 12.64 m/s
Hence, this is the required solution.
Answer:
4.9 kg.m/s.
Explanation:
Given that
mass ,m = 0.7 kg
Initial speed , u = 5 m/s ( Towards + x direction)
Final speed ,v= -2 m/s ( Towards - x direction)
We know that linear momentum is given as
P = Mass x velocity
Change in the linear momentum ΔP will be
ΔP = m ( v - u)
Now by putting the values in the above equation ,we get'
ΔP= 0.7 ( -2 - 5 ) kg.m/s
ΔP= - 4.9 kg.m/s
The magnitude of the change in the linear momentum will be 4.9 kg.m/s.
