First you find the frequency which is. 1/T(period) so u get 1*10^10
Now that you know frequency u can solve for speed: s= wavelength* frequency, but don't forget to convert 3cm into meters: 3/100= .03m so now you do (1*10^10)(.3)= 300,000,000 m/s or 3*10^8 m/s
Hope this helped :))
Answer:
Density is the amount of mass in a specified space. It is a way to measure how compact an object is
Explanation:
Work = Force x Distance = 500 x 4 = 2000 Nm = 2000 J
The heat and energy of coal burning is more easier and more efficient to turn into electricity than any method using renewable resources.
Fg=m•g || IE: Weight = mass x gravity
Therefore, the relationship are as follows:
mass and gravity are inversely proportional
mass and weight are directly proportional
weight and gravity are directly proportional
