Answer:
she should write about how big is it and what the sun looks and how far away is it from earth.
Answer:
No it is Not because win ratio is differs say Ohio only won 7 out of 7 games and e
was in the playoffs while Alabama won 11 out of 11 games so it is harder to win 11 out of 1a games and it is easier to win 7 out of 7
Explanation: would like brainliest but u don’t have to
Maybe the word could be converted?
Answer:
Option b
Explanation:
An object is said to fall freely when there is no force acting on the object other than the gravitational force. Thus the acceleration of the object is solely due to gravity and no other acceleration acts on the body.
Also the initial velocity of the body in free fall is zero and hence less than the final velocity.
As the body falls down closer to earth, it experiences more gravitational pull and the velocity increases as it falls down and the moment it touches the ground the period of free fall ends at that instant.
Thus the final velocity of an object in free fall is not zero because the final velocity is the velocity before coming in contact with the ground.
Answer:
The magnitude of the resultant decreases from A+B to A-B
Explanation:
The magnitude of the resultant of two vectors is given by
![R=\sqrt{A^2 +B^2 +2AB cos \theta}](https://tex.z-dn.net/?f=R%3D%5Csqrt%7BA%5E2%20%2BB%5E2%20%2B2AB%20cos%20%5Ctheta%7D)
where
A is the magnitude of the first vector
B is the magnitude of the second vector
is the angle between the directions of the two vectors
In the formula, A and B are constant, so the behaviour depends only on the function
. The value of
are:
- 1 (maximum) when the angle is 0, so the magnitude of the resultant in this case is
![R=\sqrt{A^2 +B^2+2AB}=\sqrt{(A+B)^2}=A+B](https://tex.z-dn.net/?f=R%3D%5Csqrt%7BA%5E2%20%2BB%5E2%2B2AB%7D%3D%5Csqrt%7B%28A%2BB%29%5E2%7D%3DA%2BB)
- then it decreases, until it becomes 0 when the angle is 90 degrees, where the magnitude of the resultant is
![R=\sqrt{A^2 +B^2+0}=\sqrt{A^2+B^2}](https://tex.z-dn.net/?f=R%3D%5Csqrt%7BA%5E2%20%2BB%5E2%2B0%7D%3D%5Csqrt%7BA%5E2%2BB%5E2%7D)
- then it becomes negative, and continues to decrease, until it reaches a value of -1 when the angle is 180 degrees, and the magnitude of the resultant is
![R=\sqrt{A^2 +B^2-2AB}=\sqrt{(A-B)^2}=A-B](https://tex.z-dn.net/?f=R%3D%5Csqrt%7BA%5E2%20%2BB%5E2-2AB%7D%3D%5Csqrt%7B%28A-B%29%5E2%7D%3DA-B)
