For light or ultraviolet, the formula for energy can be
calculated using Planck’s equation. That is:
E = h c / ʎ
where,
h is the Planck’s constant = 6.626 * 10^-34 m^2 kg
/ s
c is the speed of light = 3 * 10^8 m/s
ʎ is the wavelength of light = 110 nm = 110 x 10^-9 m
So calculating for energy E:
E = (6.626 * 10^-34 m^2 kg / s) * (3 * 10^8 m/s) /
(110 x 10^-9 m)
E = 1.807 x 10^-18 J
Potential energy is like energy contained. It is not energy displayed.
So option (a) clearly represents energy contained.
a. A cat sitting on the fence
If the cat jumps off the wall, the potential or contained energy is displayed as kinetic energy; which is energy in motion.
Answer:
speed in km/min:
0.3km/min
speed in km/h:
18km/h
speed in m/s:
5m/s
Explanation:
the average speed is defined as:

where
is the speed,
is the distance traveled, and
is the time
according to the statement:

and
(10 minutes are equal to a sixth of an hour which is 600 seconds)
Because the units in which the speed is required are not indicated, here are some options for the answer:
Depending on the units in which you need the speed, are the quantities you should use.
Speed in km / h (kilometers per hour):

speed in m / s (meters per second):

or the speed in km/min (kilometers per minute)

Explanation:
Because it's a power to turn the wheels of industry
Products such as antifreeze are composed of organic compounds that are classified as <em>alcohols</em>. (a)
Maybe those other classes of chemicals also lower the freezing temperature of water, just like alcohol does. I don't know. But alcohol is what's used to make anti-freeze. I'm guessing alcohol must be cheaper, less toxic, and less corrosive inside the engines' cooling systems than any of that other stuff is.
