What is the difference between self-pollination and cross-pollination?
Serhud [2]

The correct answer is that during cross-pollination the pollen grains are carried from one plant to another plant. During self-pollination, the pollen and ovules are from the same plant.

In self-pollination, the pollen from the anther is deposited on the same flower's stigma, or on the stigma of another flower of the similar plant. In comparison, out-crossing or cross-pollination results in greater genetic diversity as the pollen grains and ovules are obtained from different plants.

Answer is at the very end

Explanation:

Given parameters:

Mass of the asteroid = 10 x 10⁹kg

Distance between the asteroid = 850km

Unknown:

Force = ?

Solution:

We can predict the outcome of this reduction in distance between the two masses using the newton's law of universal gravitation.

The law states that "the gravitational force of attraction between two masses is directly proportional to the product of their masses and inversely proportional to the square of the distances between them".

 Mathematically, we have;

          F =

F is the gravitational force

G is the universal gravitational constant = 6.67 x 10⁻¹¹Nm²kg⁻²

m is the mass of the body

r is the distance between them.

 From this, we know that as the separation increases, the force of gravitation will reduce since the mass is constant.

The distance between the two asteroids decreased from 1000km to 850km, this will increase the force of attraction between them and we expect the force to be higher than 6700N.

 At 1000Km, force = 6700N,

 since as the distance reduces the force increases, we expect the force to be about 9200N.

Let us verify this by plugging the values into the equation:

       F =

      F = 9200N
