here two forces are acting at different angles and we need to find its resultant
forces are given as
@125 degree
@200 degree
now in order to find its resultant we will find its components
here it is given as
Now net force in x and y direction is given as
so net force is given as
now the magnitude is given as
angle of the force is given as
so net resultant force is 917.13 N at 163.4 degree
Answer:
We say that the object's spectrum is shifted.
Explanation:
Spectral lines will be shifted to the blue part of the spectrum1 if the source of the observed light is moving toward the observer, or to the red part of the spectrum when is moving away from the observer (that is known as the Doppler effect).
That shift can be used to find the velocity of the object by means of the Doppler velocity.
(1)
Where is the wavelength shift, is the wavelength at rest, v is the velocity of the source and c is the speed of light.
Answer:
Explanation:
The magnetic force between two current-carrying wires is given by:
where
is the vacuum permeability
I1 and I2 are the two currents
r is the distance between the wires
Here we have:
Substituting into the equation,
That is a vector. It is a combination of direction and velocity. (You can think of Vector from Despicable Me to help you remember the term)
