A certain fluid (with properties listed below) is heated from 25 to 75 °C as it moves at 0.2 m/s through a straight thin-walled

tube of 12.7-mm diameter. The tube is 10 m long and provides a uniform heat flux. The fluid enters the tube with a fully developed velocity profile and a uniform temperature profile.
a) What is the required heat flux?
b) What is the thermal entrance length?
c) What is the surface temperature of the tube at the exit (x-3 m)?
d) What is the surface temperature of the tube at a distance of 0.5 m from the entrance?

If two objects are moved closer together so that the distance between them is one-third the original distance, what is the gravi
r-ruslan [8.4K]
Answer:
nine times the original gravitational force
Explanation:
The rule of the gravitational force between two bodies is shown in the attached images.
The parameters in the rule are:
Fg : the gravitational force between the two bodies
G : universal gravitational constant
m1 and m2 : the masses of the two bodies
r : the distance between the two bodies

From the given rule, we can notice that:
The force of attraction between the two bodies is inversely proportional to the square of the distance between them.
This means that:
As the distance decreases to 1/3 its original value, the gravitational force would increase by a factor of 9. 

Hope this helps :)

A bar slides vertically between two conducting rails without friction in a magnetic field. The rails are connected via a resisto
Gala2k [10]

Answer:

The energy dissipated is  E =  9.8 J

Explanation:

From the question we are told that

    The distance covered at constant velocity d =  2 m  

      The velocity is  v = 1.5 \ m/s

Generally at constant velocity the magnetic  force on the bar is mathematically represented as

         F  =  m * g

substituting values

        F  =   0.5 *  9.8

        F  =   4.9 \ N

The energy dissipated is mathematically evaluate as

         E =  F * d

 substituting the value

         E =  4.9  * 2

        E =  9.8 J

Why is physics the hardest subject
horrorfan [7]
Physics can demand that you start with a specific result and make general rules. Not reading the text and not solving exercises makes understanding almost impossible. It also involves a lot of math which most people do not like.
