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:
Time, t = 80 seconds
Explanation:
Given that,
The frequency of the oscillating mass, f = 1.25 Hz
Number of oscillations, n = 100
We need to find the time in which it makes 100 oscillations. We know that the frequency of an object is number of oscillations per unit time. It is given by :
t = 80 seconds
So, it will make 100 oscillations in 80 seconds. Hence, this is the required solution.
Answer:
the particle experiences maximum force when it will be moving perpendicular to magnetic field.
it experiences minimum deflecting for when its going parallel to the magnetic field.
Explanation:when a charged particle is moving
magnetic field is B which is a vector
Magnetic force on a charge is F
formula for force F =Q.(VxB)
magnitude of the charge particle is Q
the vector multiplication of (VxB) if most significant when the charge particle is moving parallel.Very minimum when moving
velocity of the charge particle is V
Answer:
43.43
Explanation:
5.746 x 7.56 = 43.43976
As the least number of desimal is two so our awnser should contain two digits after the decimal point.
Ans: 43.43.
MgCl2 is Magnesium chloride
