Answer:Cross-pollination is two plants that work together to pollinate and self-pollinate is when a flower pollinates itself. ... Why do you think plants surround the seeds with a yummy fruit? To protect the seeds so that they can reproduce. How is cross-pollination different from self-pollination?
Explanation:
Answer:
Yes. Check reason below
Explanation:
Yes the color of materials has a role in regulating the heat. This is because colors vary in their abilities to absorb heat energy.
The ability of colors to absorb heat decreases with a decreasing wavelength. As the wavelength decreases, the color becomes cooler because of a decrease in the rate of heat absorption. Red, Orange, Yellow, Green, Blue, Violet ( In order of decreasing wavelength)
The higher the ability to absorb heat energy, the hotter the body is. Black color absorbs more heat than other colors, hence is hotter than other colors. Colors that have high reflective ability ( ie. reflect back a large portion of the light that falls on them) are a lot cooler than those with high absorptive ability. An example is white ( a combination of all visible lights)
Therefore, in designing the seating of a wheel the color should be highly considered for heat regulation.
Answer:
V = 5.67 V
Q' = 2.09 x 10^-4 C
Explanation:
Potential difference, V = 5.67 V
Charge, Q = 3.49 x 10^-5 C
dielectric constant, K = 5.99
Capacitance of the capacitor
C = Q / V = 3.49 x 10^-5 / 5.67 = 6.15 x 10^-6 F
Now the dielectric is inserted, so,
C' = K x C = 5.99 x 6.15 x 10^-6 = 3.687 x 10^-5 F
After insertion of dielectric, as the battery is connected, so potential difference remains same.
Charge, Q' = C' x V = 3.687 x 10^-5 x 5.67 = 2.09 x 10^-4 C
The sun typically emits EW from infrared to UV. During solar flares it can emit x-rays and there have been instances of gamma ways but they lose energy before reaching earth.
Answer:
gravitational force increases
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are brought closer to each other, the force of gravitational attraction between them also increases.
