How does the structure of the stigma aid in pollination

Physics
1 answer:
natali 33 [55]3 years ago
5 0
<span>Pollination is the process by which pollen is transferred to the female part of a plant. The stigma is the central part of the flower, that is supported by a style and is part of the female reproductive organ within plants. Its structure is optimised to promote pollination by having hairs, sticky surfaces and three-dimensional sculptures that capture and trap pollen.</span>

What is the net force needed to lift a full grocery sack weighing 210N uniformly?
Alex
If the sack weighs 210 newtons, then an upward force of 210 newtons
exactly cancels the downward force of gravity, and makes the net vertical
force on the bag zero. 

ANY upward force that's greater than 210 newtons makes the net force
act upward on the bag, and causes it to accelerate upward.

Assuming that 70 percent of the Earth’s surface is covered with water at average depth of 0.95 mi, estimate the mass of the wate
Alla [95]

Answer:

The mass of the water on earth is 5.4537\times10^{20}\ kg

Explanation:

Given that,

Average depth h= 0.95 mi

h=0.95\times1.609

h =1.528\ km

h=1.528\times10^{3}\ m

Radius of earth r= 6.37\times10^{6}\ m

Density = 1000 kg/m³

We need to calculate the area of surface

Using formula of area

A =4\pi r^2

Put the value into the formula

A=4\pi\times(6.37\times10^{6})^2

A=5.099\times10^{14}\ m^2

We need to calculate the volume of earth

V = Area\times height

Put the value into the formula

V=5.099\times10^{14}\times1.528\times10^{3}

V=7.791\times10^{17}\ m^3

Now, 70 % volume of the total volume

V= 7.791\times10^{17}\times\dfrac{70}{100}

V=5.4537\times10^{17}\ m^3

We need to calculate the mass of the water on earth

Using formula of density

\rho = \dfrac{m}{V}

m = \rho\times V

Put the value into the formula

m=1000\times5.4537\times10^{17}

m =5.4537\times10^{20}\ kg

Hence, The mass of the water on earth is 5.4537\times10^{20}\ kg
