A.how much power is needed to push the box at a speed of.
Explanation:
Initial speed of blood, u = 0
Final speed of the blood, v = 26 cm/s
(a) Displacement of the blood, d = 2 cm
Let a be its acceleration. It can be calculated using third equation of motion as :
(b) Let t is the time taken by the blood to reach its final speed. It can be calculated as :
<u></u>
t = 0.15 s
Hence, this is the required solution.
The answer is A, transporting nutrients
The number of outcomes in the compliment of the event are 0.54
<h3>Concept and calculation</h3>
No of strawberry plants in the field = 259259
No of plants that are ready for picking = 142142
so no of outcomes = 142142/ 259259 = 0.54 outcomes
<h3>Understanding of probability</h3>
The area of mathematics that deals with probability is called probability theory.
Probability is a concept that can be interpreted in a variety of ways, but probability theory tackles the idea in a rigorous mathematical way by expressing it through a series of axioms.
Typically, these axioms formalize probability in terms of a probability space, which links a collection of outcomes known as the sample space to a measure taking values between 0 and 1. An event is any defined subset of the sample space.

The molar latent enthalpy of boiling of iron at 3330 K is ΔH = 342 10^3 J.
<u>Explanation:</u>
Molar enthalpy of fusion is the amount of energy needed to change one mole of a substance from the solid phase to the liquid phase at constant temperature and pressure.
d ln p = (ΔH / RT^2) dt
(1/p) dp = (ΔH / RT^2) dt
dp / dt = p (ΔH / RT^2) = 3.72 10^-3
(p) (ΔH) / (8.31) (3330)^2 = 3.72 10^-3
ΔH = 342 10^3 J.
