A) the final velocity = 66/9 m/s.
b) The total momentum before and after collision is the same because energy is destroyed or made.

Answer:
(A)The water will freeze.
Explanation:
Heat is the energy that when transferred causes change in temperature. If heat is added to a body by some process the bodies temperature increases and if heat is removed from a body by some process the temperature reduces.
In this case if enough heat is removed from the room the internal movement of the water particles will slow down causing the water to form crystal lattice thus forming ice. So, the water will freeze.
Answer:
The current increases.
Explanation:
A capacitor can be defined as an electronic component used in electrical circuits to store charge temporarily.
A capacitor is connected to an AC generator. As the generator's frequency is increased, the current in the capacitor increases as well.
This ultimately implies that, when a capacitor is connected to an AC generator, the frequency of the circuit is directly proportional to the amount of current flowing through it.
Answer:
MRI
Explanation:
Magnetic Resonance Imaging, furnishes the most detailed picture of brain structure. MRI produces the most point by point picture of the cerebrum. MRI examines by using attractive fields and radio waves to create PC produced pictures that recognize the structures inside the mind. It gives the most point by point and a detailed image of the brain structure.
ANSWER:
Angular displacement is analogous to distance.
Angular velocity is analogous to velocity.
EXPLANATION:
FOR ANGULAR DISPLACEMENT AND DISTANCE
Angular displacement = theta
theta = s/r
s = linear dispalcement/distance
r= radius.
so ,
linear displacement/distance s = theta * r.
FOR ANGULAR VELOCITY AND VELOCITY
Angular velocity = w
w = v/r
v = velocity
r = radius
so,
velocity v = w * r.
