Answer: 9600 J</h2>
The kinetic energy 
of a body is that energy it possesses due to its movement and is defined as:
Where 
is the mass of the body and 
its velocity
.
This has to do with the speed of an object and how much mass it has; basically how the object is moving.
Now, according to this equation and knowing that the mass of the buffalo is 
and its velocity 
:
Therefore the correct option is B.
Answer:
Non-contact is a force that acts on an object without physically coming into contact with it.
Explanation:
There was no following. If is not the answer that your looking for sorry.
Answer:
It can occur only when light is incident on an interface where the index of refraction on the other side is less.
Explanation:
When the light passes from a denser medium, with refractive index n1, to another less dense medium, with refractive index n2, the incident light beam is refracted in such a way that it is not able to cross the surface between both media, the light beam is fully reflected and completely confining in the optically denser medium through which it propagates. For this phenomenon to occur, it is necessary that the angle of the incident light beam with respect to the normal be greater than or equal to the critical incidence angle θc. The critical angle can be calculated as :
Answer:
Color
Explanation:
Thus, for stars, considering them as “black bodies”, we can get an approximate figure for their temperature by measuring their dominant frequency (color). Technically scientists measure the brightness of the blue light and that of red light from the star, and from this they can calculate the temperature of the star.
Hermes has a rotating wheel, or centrifuge, to provide artificial gravity for the crew. Spaceships in “2001: A Space Odyssey” and “Mission to Mars” were similarly equipped. Although it is not shown in the film, the astronauts would have used a Mars descent vehicle (MDV) to get down from Hermes to the surface.
