Answer:
The maximum temperature is 90.06° C
Explanation:
Given that
t= 0.1 mm
Heat generation
Heat transfer coefficient
Here one side(left side) of the wall is insulated so the all heat will goes in to right side .
The maximum temperature will at the left side.
Lets take maximum temperature is T
Total heat flux ,q
So the total thermal resistance per unit area
R=0.002 K/W
We know that
q=ΔT/R
30=(T-90)/0.002
T=90.06° C
The maximum temperature is 90.06° C
C. Bottom
Titania speaks these words as she is under the enchantment of the magic flower, it makes her fall in love with the first thing she sees. It's comedic because Bottom is also enchanted to have the head of a donkey, so she's claiming that this peasant with a donkey head is both wise and beautiful. The reality being that he is as wise as he is beautiful, in that he is neither beautiful nor wise.
Answer:
The magnitude of the vector A is <u>51 m.</u>
Explanation:
Given:
The horizontal component of a vector A is given as:
The vertical component of a vector A is given as:
Now, we know that, a vector A can be resolved into two mutually perpendicular components; one along the x axis and the other along the y axis. The magnitude of the vector A can be written as the square root of the sum of the squares of each component.
Therefore, the magnitude of vector A is given as:
Now, plug in 44.4 for , 25.1 for and solve for the magnitude of A. This gives,
Therefore, the magnitude of the vector A is 51 m.
Answer:
1)force:- force is an external affert by any body on an object.
2) force and motion are related to each other. force helps to create motion in any object.
3) frictional force
4) Newton
The mass of material is 26.6 Kg
Given:
Q = 4720 KJ
Change in Temperature (AT) = 65 K
Specific heat capacity of material (c) = 2730 J K Kg*K
The relation between Q, AT, c and m are related by following formula: Q=m* c*∆T,
Plugging value in heat formula:
4720KJ = m* 2730 J/Kg*K * 65K
4720KJ = m * 177450J/kg
Converting 177450 J/kg to Kg/KJ
177450 J/kg*1KJ/1000J = 177.450KJ/kg
Dividing both side by 177.450KJ/kg
4720KJ/177.450KJ/Kg = m*177.450KJ/Kg÷ 177.450KJ/Kg
Hence, the mass of material = 26.6 Kg
