<span>Pollination is when the male gamete or pollen reaches the female flower through different modes...wind,air,animals,...
Fertilization </span><span>is when the male gamete "join" with the female gamete to become an embryo.
I hope I helped.:) </span>
The simplest answer would be "acceleration due to gravity."
The exact value of this acceleration changes depending on which planet your on (for example).
According to the conservation of momentum. In this situation, the initial momentum is equal to zero.
Since,
p=mv (Momentum)
The initial velocity of the ball = 0 m/s
The initial velocity of the man = 0 m/s
Therefore,
Total Momentum = 0
Law of Conservation of momentum states that the vector sum of the final momenta must be equal to zero which means they will have the same magnitude but in opposite directions.
<span>When the ball is kicked forward along the surface with a speed 15 m/s.
</span>then the momentum will be:
p = 4 x 15 = 60 kgm/s.
Now, the momentum of the man can be calculated as:
p = 60 kgm/s
mv = 60 kgm/s
As,
mass of the man = 80kg
So,
80 × v = 60 kgm/s
v = 60÷80
v = 0.75 m/s
Answer:
With a person’s blood pressure is measured to be 120 ± 2 mmHg, it will be 1.2mmHg
Explanation:
What is missing in the question is the percentage of uncertainty.
If we assume that a person’s blood pressure is measured to be 120 ± 2 mmHg, the percent uncertainty is computed as:
% uncertainty = 2mmHg/120mmHg x 100% = 1.7%
So,
The uncertainty in the blood pressure is = 1.7% / 100% * 71mmHg = 1.2mmHg
If you're given the force and the length of time that the force acted,
then you can determine momentum, with units of [mass-length/time].
Without more information, you can't determine power, watts, energy,
joules, or distance.
