Answer:
Therefore the magnitude of tangential velocity is 20 m/s.
Explanation:
Tangential velocity:The tangential velocity is the straight line velocity of at any point of rotating object.
It is denoted by
ω= angular velocity
r = radius of rotating object.
Angular velocity: Angular velocity is ratio of angle to time.
Here ω= 50 rad/s and r = 0.4 m
Tangential velocity=(50 ×0.4)m/s
=20 m/s
Therefore the magnitude of tangential velocity is 20 m/s.
Answer:
n = 1000 pulses
Explanation:
Given that,
The frequency of a pulse waveform,
To find,
The number of pulses counted during 100 ms.
Solution,
The frequency of a pulse waveform is equal to the number of pulses per unit time. It is given by :
n = 1000 pulses
So, there are 1000 pulses counted in a pulse waveform.
Increasing mass increases kinetic energy. This can be seen in the equation KE = 1/2 (m) (v)^2

Answer:
Explanation:
Given
mass of saturated liquid water
at specific volume is (From Table A-4,Saturated water Temperature table)
Final Volume
Specific volume at this stage
Now we see the value and find the temperature it corresponds to specific volume at vapor stage in the table.
