Both the effects (l<span>engthening of the transmitted signal's wavelength and decrease in its frequency) indicates that the object is moving away from the observer, and this phenomenon is called Doppler effect.
In fact, when the object is moving away from the observer, the relative distance between two consecutive crests of the wave emitted by the object increases to the observer eyes, since he's moving away. This means that the wavelength appears larger, and since the frequency is inversely proportional to the wavelength, the frequency appears smaller.</span>
Answer:
false
Explanation:
bc the faster car has more inertia (i dont think im correct)
not sure but feels like it
A range of infrared wavelengths <span />
Answer:
a. Decreases
b. Increases
c. Remains the same
d. Increases
Explanation:
a. Capacitance is given by c= Ak€/d
where A is conductivity plate with Area
K is a constant
€ is dielectric with permittivity.
d is the distance
b. Potential difference is given by
V = Ed, since, the electric field remains the
same, the potential diterence also increases with increase in distance.
Since the capacitance depends upon the distance, and all the other factors are kept constant, the capacitance decreases.
c. Electric field remains the same because charge on the
plate remains the same.
d. since electric field remains the same and capacitance decreases, the energy increases.
E= 1/2c * Q^2
Answer:
20.35m per minute
Or
1,221.43 per hour
100/5=20
200/7= 28.57
50/4= 12.5
20+28.57+12.5= 61.07
61.07/3= 20.35m per minute
Or
20.35 x 60= 1,221.43m per hour
