the difference is Pollination occurs from anthers of stamens to stigma of the ovary and It is a physical process.
fertilizateion is It is the fusion of female and male gametes and It is a genetic and biochemical process.
Explanation:
this was so hard to write out
Answer:
18600j
Explanation:
It is given that,
Number of moles = 3
Temperature, T = 25°C = 25+273 = 298 K
The internal energy of N₂ gas is given by :
U=f\times nRTU=f×nRT
f is degrees of freedom. For diatomic gas, degree of freedom is equal to 5/2. So,
\begin{gathered}U=\dfrac{5}{2}\times 3\times 8.31\times 298\\\\U=18572.85\ J\end{gathered}
U=
2
5×3×8.31×298
U=18572.85 J
or
U = 18600 J
So, the internal energy of the gas is 18,600 J
Answer:
The distance covered by the rocket after fuel ran out is
Explanation:
Given that the rocket moves with an acceleration
time
Since the rocket starts from rest initial velocity
The distance it travelled within this time is given by
Velocity at this point is given by
Given that at this height it runs out of fuel but travels further. Here final velocity (maximum height), initial velocity and time to zero velocity
Thus it travels more after fuel running out. The distance covered during this period is given
Hello there!
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
Answer:
both caused by physical vibrations
