Answer:
because the strength of Earth's gravitational field is not uniform everywhere, a given pendulum swings faster, and thus has a shorter period, at low altitudes and at Earth's poles than it does at high altitudes and at the Equator.
If you were given distance & period of time, you would be able to calculate the speed.
Hope this helps!
Answer:
Ultraviolet light has a shorter wavelength than infrared light.
Explanation:
Electromagnetic waves are waves that does nor require material medium for their propagation. Example of Electromagnetic waves are classified according to the acronym RIVUXG. They decrease in wavelength and increase in frequency from Radiowaves to Gamma ray.
R is the Radio waves
U - ultraviolet ray
V - Visible light (ROYGBIV){Red, Orange, Yellow, Green, Blue, Indigo and Violet}
Note that the visible light also decrease in wavelength from red to indigo, therefore red will have longer wavelength compare to blue light.
I - Infrared rays
X - X ray
G - Gamma ray
Based on the above conclusion, it can be inferred that Ultraviolet light has a shorter wavelength than infrared light since Infrared rays comes before the infrared light in the electromagnetic spectrum.
