Answer = 330 m/s
The wave equation is as follows:
Wave speed = wavelength x frequency
The known values are:
Wavelength = 3m
Frequency = 110 Hz
Substitute the known values into the wave equation to find the wave speed.
Wave speed = 3 x 110
Wave speed = 330 m/s
Managing and looking after a port environment. They were also
vegetarian. Smoke led to pollution, so there were laws passed that
factories could not be built where other buildings could be affected.
There were also water systems and sewage systems that carried water to
people and carried sewage away from people who could afford it at the
time.
The sample appears to have gone through 3 half-lives
1st half life: 1000 to 500 g
2nd half life: 500 to 250 g
3rd half life: 250 to 125 g
The duration of a half-life, therefore, can be inferred to be 66 ÷ (3) = 22 days.
After a 4th half life, there will be 125÷2= 62.5 g.
At this point, an additional 22 days will have passed, for a total of 88 days.
Answer is C.
A conservative force is a force that when work is done against this force the work done does not depend on the path taken only the initial and final position.
