Answer:
Explanation:There are many reasons why water is not used as a thermometric liquid (or is less preferred), chief among which is its transparency. It is thus comparatively harder to make any readings with it. It also has a lower boiling and higher freezing point compared to most liquids.
Answer:
The distance is, y = 489.5 [m/s]
Explanation:
To solve this problem we can use the following equation of kinematics.
where:
Vf = final velocity = 98 [m/s]
Vi = initial velocity = 0
g = gravity acceleration = 9.81 [m/s^2]
y = distance [m]
(98^2) = 0 + (2*9.81*y)
Note: the positive sign of the equation means that the acceleration of gravity acts in the direction of the movement of the object.
9604 = 19.62*y
y = 489.5 [m/s]
C. I did it bit i forgot how I did it
The change in direction of a wavepassing from one medium to another caused by its change in speed
I just solved similar type of question. You can refer to my solution which I have attached
