Answer:
Wavelength = 9.68 meters
Explanation:
Given the following data;
Speed = 300,000,000m/s
Frequency = 31 Megahertz to Hertz = 31 * 10⁶ Hz
To find the wavelength;
Wavelength = speed/frequency
Wavelength = 300,000,000/31,000,000
Wavelength = 9.68 meters
Answer:
Expression of work done is
Work done to move the sled is given as 187.2 J
Explanation:
As we know that the formula of work done is given as
here we know that
F = 12.6 N
d = 15.4 m
so we will have
