Question 10 of 10 Which three applications use technologies that apply the Doppler effect?
O A. Air-traffic control
B. Pest control
O C. Building inspection
D. Weather forecasting

police and radar

Explanation:

the doppler effect is used by meteorologists to teach storms

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
