Answer:
The speed of the aircraft relative to the ground is 606.9
Explanation:
x-y coordinate system:
x is Positive due East direction. Similarly y is Positive due North Direction.
Now let us Decompose each vector into x-y
500 km/h due east = (500, 0)
120 km/h at 30 degree north of east
=
=
=
Adding the vectors.
=
=
=
=
= (603.8, 60)
Returning back to polar form
Magnitude =
Answer:
f = 4 Hz
Explanation:
Given that,
The speed of a wave, v = 12 m/s
The wavelength of a wave,
We need to find the frequency of the wave. We know that the speed of wave is equal to the product of wavelength and frequency. So,
So, the frequency of the wave is equal to 4 Hz.
A single electron has a charge of
Therefore, if we have an excess of
electrons, the total net charge will be the product between the charge of a single electron and the total number of electrons in excess:
Therefore, if we have an excess of
