Convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
Ideal M.A. is 1 I.e, load =effort
Answer:
-22/15
Explanation:
the least common denominator is 15 so first you multiply -2/3 by 5 in both the numerator and denominator making it -10/15
Then you do the same to -4/5 except you multiply the numerator and denominator by 3 giving you -12/15
If you add -10/15+ -12/15 you get -22/15
Answer:
D.400 watt
Explanation:
- B/c <em>Pave</em><em>=</em><em>Irms</em><em>Vrms</em>
- <em>Pave</em><em>=</em><em>(</em><em>5</em><em>)</em><em>(</em><em>8</em><em>0</em><em>)</em>
- <em>Pave</em><em>=</em><em>4</em><em>0</em><em>0</em><em> </em><em>watt</em>
<em>where</em><em> </em><em>Pave</em><em> </em><em>=</em><em> </em><em>average</em><em> </em><em>power</em><em> </em>
<em>Irms</em><em>=</em><em>RMS</em><em> </em><em>current</em><em> </em><em>&</em>
<em>Vrms</em><em>=</em><em>RMS</em><em> </em><em>voltage</em>
Answer:
Current through the surface at t = 1.1 s is 21.37 A.
Explanation:
The charge is passing through a surface of area varies with time as :

Here,

t is in seconds

The rate of change of electric charge is called electric current. It is given by :

At t = 1.1 s, Current,

So, the instantaneous current through the surface at t = 1.1 s is 21.37 A.
