I think what’s wrong is that the paper clip isn’t connecting to the other thing on the bottom
Answer:
The frequency , speed and wavelength of an electromagnetic wave are related by the formula
Speed = frequency x wavelength
frequency = speed / wavelength
substituting the values
frequency = 3 x #10 ^8# m /s / 1 x #10^15# m
= 3 x #10^-7# /s
False because the allocation rule of "first come-first served" promotes productive cooperation.
Answer:
v = 42.33 m/s
Explanation:
The time difference between two pulses that are emitted by Police is observed in the interval

now the speed of the electromagnetic wave is given as

now the distance traveled by them



so distance of speeding vehicle covered for round trip of wave is 38.1 m
now for one trip it is given as d = 19.05 m
now the speed of the vehicle is given as



Answer:
Part A: 
Part B: 
Part C: 
Explanation:
Part A:
We will use the following kinematics equation:

Part B:
We will use the same kinematics equation:

Part C:
The total time takes is 2t.
So the train moves a distance of

And the car moves a distance in Part A and in Part B:

So the total distance that the car traveled is 
The difference between the train and the car is
