Answer: Option 3.
Explanation:
Formula for kinetic energy is
K.E = (1 / 2) * (m * v ^ 2)
Assuming mass to be constant,
We can see that K.E is proportional to v^2.
It means that when you substitute the value of velocity in v, kinetic energy increases with v^2.
Option 1 and 2 are eliminated because the relationship between kinetic energy and velocity in the graph is shown as linear. We already know from formula that the relationship is not linear.
Option 4 is incorrect because kinetic energy must be zero when velocity is zero. This graph shows kinetic energy is becoming infinite as velocity tends to 0.
So option 3 is correct answer.
Answer:
. A chemical reaction is the rearranging of atoms to form new substances. E=mc^ aleph
Clues or evidence
Im pretty sure its evidence though
It looks that way cause the earth is rotation on its axis
Answer:
D) Since the stars would move from East to West just as the Sun and Moon do.
