Answer:
65 Hz, 95 Hz, 150 Hz, 180 Hz, 310 Hz, 340 Hz
Explanation:
Given :
Frequencies of the sinusoids,
, and
Sampling rate
The positive frequencies at the output of the sampling system are :
When n = 0,
when n = 1,
When n = 2,
Therefore, the first six positive frequencies present in the replicated spectrum are :
65 Hz, 95 Hz, 150 Hz, 180 Hz, 310 Hz, 340 Hz
The most common formula for average speed is distance traveled divided by time taken. The other formula, if you have the initial and final speed, add the two together, and divide by 2.
S= d/t
Answer:
Height h= 1.7 m
Explanation:
Supposing we have to find height in meter.
1 feet = 0.3048 m
1 inch = 0.0254 m
Given that:
5 feet
= 5×0.3048
= 1.524 m
and 7 inch = 7×0.0254= 0.1778 m
Therefore total height of a man in meter
5 feet 7 inch = 1.5424+0.1778 =1.7 m
Height h= 1.7 m
Answer:
d. 6/5 M.
Explanation:
let the angular velocity =
the radius of sphere (r) =
moment of inertia of solid sphere =
rotational K.E of solid sphere=
=
we represent the mass of hallow sphere=
moment of inertia of solid sphere =
rotational K.E of hollow sphere=
=
NOW,the kinetic energy of solid sphere= 1/2 kinetic energy of hallow sphere
=
2/5M= 1/3
= 3(2/5M)
= 6/5 M
