Distance between the focal point and the center of the lens
Wavelength and frequency are directly related to one another. Low frequency but high wavelength signals tend to be easier to detect. Examples of these signals are the radio waves.
I hope my answer has come to your help. God bless and have a nice day ahead.
Speed = Distance ÷ Time
Speed = 116 ÷ 29
Speed = 4
Answer:
B) converging tectonic plates
Explanation:
Potential Energy=m.g.h
=weight.height.gravity
Energy of Ball=19.45.g
We normally do not use gravity while calculating.
Energy=855
If you want to know g of earth is 9.8
You can calculate if you want
