|Acceleration| = (change in speed) / (time for the change).
Change in speed = (6 mi/hr - 25 mi/hr) = -19 mi/hr
Time for the change = 10 sec
|Acceleration| = (-19 mi/hr) / (10 sec) = -1.9 mile per hour per second
Admittedly, that's a rather weird unit.
Other units, perhaps more comfortable ones, are:
-6,840 mi/hr²
-2.79 feet/sec²
Answer:
Using the kinetic theory, explain the rise of water in a glass capillary tube. ... Glass and water are composed of different molecules. The force of attraction between the glass molecules and the water molecules is stronger than that among water molecules hence the rise of water in the tube.
Explanation:
its the specifics of science
Answer:
Explanation:
First of all, we need to calculate the energy of the x-ray photon emitted during the transition from K-shell to L-shell, and this energy is equal to the difference in energy between the two levels:
Converting into Joules,
Now we know that the energy of the photon is related to its wavelength by:
where
h is the Planck constant
c is the speed of light
is the wavelength
Re-arranging the equation for , we find
Answer:
solid liquid and gas are the events
