Answer:
Explanation:
Given
mass flow rate=0.3 kg/s
diameter of pipe=5 cm
length of pipe=10 m
Inside temperature=22
Pipe surface =100
Temperature drop=30
specific heat of vapor(c)=2190 J/kg.k
heat supplied 
Heat due to convection =hA(100-30)

Answer:
The Angle between the vector A and B is 12.32°
Explanation:
Given data
|A×B|=32
|A|=10
|B|=15
To find
Angle α
Solution
From Cross product properties we know that

The Angle between the vector A and B is 12.32°
The acceleration of gravity on Mars is about 3.7 m/s². (b)
So anything located on the surface of Mars weighs about 38% of what it would weigh if it were on Earth.
