Find the length of the mercury column in a
simple barometer when the barometer is raised
from sea level to a height of 2.5 km given that
the average density of air is 1.2 kgm and the
density of mercury is 1.36 x 104 kgm
Atmospheric pressure at sea level is 76 cm of
mercury

the results is a decrease in air temperature with an increase of altitude.

explanation:

show the wavelengths of a wave. show the crests of a wave.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
