In the equation for the gravitational force between two objects "d" quantity must be squared.
<u>Answer:</u> Option D
<u>Explanation:</u>
The force that attracts two objects with mass is called as gravitational force. This has been explained by "Newton's Universal Law of Gravitation" which says "In this universe every single particle attract every other particle with a force which directly proportional to the product of their masses while inversely proportional to the square of the distance in between them. "
The gravitational force between any two objects with masses can be calculated by given formula:
F = G (m1 . m2 / d^2)
Here the F is gravitational force,
G is the gravitational constant = 6.67 × 10^-11
m1 and m2 are the masses of the two objects
d^2 also represented as r^2 is the distance between two objects.
Answer:
C
Explanation:
Cloning reproduces the exact same crops identical to the plant from which the cloning tissue was taken. While this has the capacity to preserve the purity of a breed of plants with desired characteristics, it can also have undesirable effects. Without sexual reproduction, there would be no genetic variability of the crop. This means the plant will hardly adapt to environmental changes and could go extinct if not further genetically engineered.
Answer:A: Composition
Explanation: While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When comets get closer to the Sun, they lose material with each orbit because some of their ice melts and vaporizes. Asteroids typically remain solid, even when near the Sun.
The answer is B proteins.
