Answer:
18m/s
Explanation:
Given parameters;
Initial velocity = 10m/s
Acceleration = 2m/s²
Time = 4s
Unknown:
Car's new velocity = ?
Solution:
We use one of the kinematics equation to solve this problem:
v = u + at
v = new velocity
u = initial velocity
a = acceleration
t = time
v = 10 + (2 x 4) = 18m/s
The path taken by pollen as it fertilizes a plant would be:
anther ---> stigma ---> style ---> ovule
The fertilization process in plant starts by pollination. Pollen grains move from the anther of a flower to the stigma of the same or different flower. On the stigma, the pollen germinates and the cells of the pollen tube grows through the style to reach the ovule.
The generative cell of the pollen travel through the pollen tube to reach the embryo sac of the ovule. The cell divides by mitosis to form sperm cells and one of the sperm cells fertilizes the egg cell to form the zygote.

Answer:
The correct answer is 28.2 %.
Explanation:
Based on the given question, the partial pressures of the gases present in the trimix blend is 55 atm oxygen, 50 atm helium, and 90 atm nitrogen. Therefore, the sum of the partial pressure of gases present in the blend is,
Ptotal = PO2 + PN2 + PHe
= 55 + 90 + 50
= 195 atm
The percent volume of each gas in the trimix blend can be determined by using the Amagat's law of additive volume, that is, %Vx = (Px/Ptot) * 100
Here Px is the partial pressure of the gas, Ptot is the total pressure and % is the volume of the gas. Now,
%VO2 = (55/195) * 100 = 28.2%
%VN2 = (90/195) * 100 = 46%
%VHe = (50/195) * 100 = 25.64%
Hence, the percent oxygen by volume present in the blend is 28.2 %.
As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets.
