An object of mass 11kg is falling in air and experiences a force due to air resistance of 35N. Determine the magnitude of net fo
1 answer:
Answer:
<em>The net force acting on the object is 72.8 Nw</em>
Explanation:
<u>Net Force in Free Falling Objects</u>
When an object is falling in the air, the default force applied to it is the gravitational force or its weight. If air resistance is considered, then the net force acting on the object must take into consideration two opposed forces
Where is the net force,
is the air resistance, and W is the weigh of the object
The net force acting on the object is

Three complete orders on each side of the m=0 order can be produced in addition to the m=0 order.
The ruling separation is d=1/(470mm-1)
Diffraction lines occurs at an angle θ such that dsin=mλ,when λ is the wavelength and m is an integer.
Notice that for a given order,the line associated with a long wavelength is produced at a greater angle than the line associated with shorter wavelength.
we take λ to be the longest wavelength in the visible spectrum (538nm) and find the greatest integer value of m such that θ is less than 90°.
That is,find the greater integer value of m for which mλ<d.
since,d/λ
There are three complete orders on each side of the m=0 order.
The second and third orders overlap.

Answer:
a) 1.2*10^{-3}cos(1.25t)
b) 0.49mV
Explanation:
a) The coil rotates periodically with period T. Hence, we can write the variation of the magnetic flux with a sinusoidal function, and with max flux NAB. Thus, we have that:
where we have used the values given by the information of the problem for N B and A.
b)
the emf is given by:
