To develop this problem we will apply the concepts related to the kinematic equations of motion, specifically that of acceleration. Acceleration can be defined as the change of speed in an instant of time, mathematically this is
![\vec{a} = \frac{\vec{v_2}-\vec{v_1}}{\Delta t}](https://tex.z-dn.net/?f=%5Cvec%7Ba%7D%20%3D%20%5Cfrac%7B%5Cvec%7Bv_2%7D-%5Cvec%7Bv_1%7D%7D%7B%5CDelta%20t%7D)
If a mobile is decreasing its speed (it is slowing down), then its acceleration is in the opposite direction to the movement. This would imply that the acceleration vector is opposite to the velocity vector.
Therefore the correct answer is B.
the worst because its not enough habitat and when the cutting down a whole lot of rainforest at a time which is killing animals escpecialy rainforest animals
This question can have ALOT of answers but ill leave you with these summed up points and you can take what you need from it they are get right to the point! Sorry if they long paragraphs scare you lol
*You want to provide patients the best care possible. Most often your patients will have a disease. Diseases result when there is something abnormal in the anatomy and physiology of a structure. With a car, you can’t understand how to fix an engine if you don’t know how it works. The same is true with your patients. You can’t really understand how to treat them or why the treatment works, if you don’t understand how the effected body system normally functions.
*Patients will want to understand their diseases. In order to help them understand what is going wrong, you have to first understand how a particular organ is supposed to work. In addition, you will need to be able to explain these things to patients in a way that they can understand. If you don’t understand it well, you won’t be able to explain it. Your patient’s confidence in your ability will be at least partially determined by your ability to discuss what you are doing and why you are doing it. You will need to look up information if you are not sure.
*Organ systems are so interconnected that a disease in one system may result in a symptom in another system. Without seeing the normal interconnectedness, you cannot fully understand the disease.
*Success in an allied health field requires at least three things. First, you must have the personality to be able to support and help patients. Secondly, you must have the scientific and technical knowledge necessary to make the correct decisions regarding patient care. Thirdly, you must have the clinical skills necessary to implement this kno

Answer:
The same as the escape velocity of asteorid A (50m/s)
Explanation:
The escape velocity is described as follows:
![v=\sqrt{\frac{2GM}{R}}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cfrac%7B2GM%7D%7BR%7D%7D)
where
is the universal gravitational constant,
is the mass of the asteroid and
is the radius
and since the scape velocity is 50m/s:
![50m/s=\sqrt{\frac{2GM}{R}}](https://tex.z-dn.net/?f=50m%2Fs%3D%5Csqrt%7B%5Cfrac%7B2GM%7D%7BR%7D%7D)
Now, if the astroid B has twice mass and twice the radius, we have that tha mass is: ![2M](https://tex.z-dn.net/?f=2M)
and the radius is: ![2R](https://tex.z-dn.net/?f=2R)
inserting these values into the formula for escape velocity:
![v=\sqrt{\frac{2G(2M)}{2R} } =\sqrt{\frac{4GM}{2R} } =\sqrt{\frac{2GM}{R} }](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cfrac%7B2G%282M%29%7D%7B2R%7D%20%7D%20%3D%5Csqrt%7B%5Cfrac%7B4GM%7D%7B2R%7D%20%7D%20%3D%5Csqrt%7B%5Cfrac%7B2GM%7D%7BR%7D%20%7D)
and we have found that
, so the two asteroids have the same escape velocity.
We found that the expression for escape velocity remains the same as for asteroid A, this because both quantities (radius and mass) doubled, so it does not affect the equation.
The answer is
Asteroid B would have an escape velocity the same as the escape velocity of asteroid A
