I think the answer would be A. Density because many headlights could have the same density, but the rest of the analysis techniques would be specific to that crime.
Answer:
Energy will be equal to 
Frequency will be equal to 
Explanation:
We have given frequency of the radar f = 10 GHz 
Speed of light 
Plank's constant 
So energy 
,here h is plank's constant and 
is frequency
So energy 
In second case we have given wavelength = 25 cm = 0.25 m
Wavelength is equal to 
So 
So frequency will be equal to
The change in the total energy of the object is zero (0).
The given parameters:
work done by the machine, W = 50 J
mass of the object, m = 10 kg
To find:
the change in the total energy of the object
The change in the total energy of the object is the difference between the objects initial energy due to its position and the work done on the object.
Based on work energy-theory, the work done on the object is equal to the energy of the object.
- The energy of the object = work-done on the object
- The change in total energy = 50 J - 50 J = 0
Thus, the change in the total energy of the object is zero (0).

Answer:
A. The pressure denoted as Pa and Pb at the surfaces of A and B in the tube is
PA= Pgas
PB= Patmos
B. The second sketch
C. The gas pressure is
Pgas= Patmos+ rho.g(h2-h1)
= 1atm + rho.g (h2-h1)
Explanation:
Answer: Electromagnetic waves are generated by moving electrons. An electron generates an electric field which we can visualize as lines radiating from the electron Figure 10a. If the electron moves, say it vibrates back and forth, then this motion will be transferred to the field lines and they will become wavy Figure 10b.
