Answer:
The correct answer is "6.96 rad/s".
Explanation:
The given values are:
Length,
L = 0.6 m
Mass,
m₁ = 0.5 kg
m₂ = 0.2 kg
Initial velocity,
V = 8 m/s
Now,
The final angular velocity will be:
⇒ 
By substituting the values, we get
⇒ 
⇒ 
⇒ 
Answer:
C
Explanation:
Force is a vector quantity. So, it has magnitude and direction which can also be describe as strength and direction
Answer:
a. 572Btu/s
b.0.1483Btu/s.R
Explanation:
a.Assume a steady state operation, KE and PE are both neglected and fluids properties are constant.
From table A-3E, the specific heat of water is
, and the steam properties as, A-4E:

Using the energy balance for the system:

Hence, the rate of heat transfer in the heat exchanger is 572Btu/s
b. Heat gained by the water is equal to the heat lost by the condensing steam.
-The rate of steam condensation is expressed as:

Entropy generation in the heat exchanger could be defined using the entropy balance on the system:

Hence,the rate of entropy generation in the heat exchanger. is 0.1483Btu/s.R
Answer: 

Explanation:
Firstly, let's convert these length to meters
, in order to work with the same units:
a. 400 millimeters

b. 22 kilometers

c. 170 meters
Here the lenght is already in meters
d. 3.3 centimeters

Now that we have all the lengths in meters, we can order them from shortest to longest:

or

Answer:
8
Explanation:
Groups go down, periods go across :)
