Answer:
Blowing on it will cool it down.
Explanation:
Air blown from peoples lungs is faster because of the small temperature difference with the hot baked potato.
Answer:
Yes, this is completely independent.
Explanation:
Yes, this is completely independent. Even though there are no South American individuals that are majoring in biomedical engineering in this party it is still a completely independent factor. The origin of birth of an individual does not tie them to a specific degree or field of expertise, therefore a South American individual can study anything they want including mechanical engineering, electrical engineering, or biomedical engineering.
Answer:
modify temperature is lower than by the 0.196 %
Explanation:
given data
D = 250 mm
d = 0.1 mm
v = 0.5 m/s
V = 50 m/s
D = 150 mm
d = 0.1 mm
v = 0.3 m/s
V = 25 m/s
solution
first we get here initial coating condition for temperature change ΔT is
ΔT = A \times D^{1/4} \times d^{3/4}\times \frac{V}{v}^{1/2} ...............1
put here value for both condition
ΔT = A \times 250^{1/4} \times 0.1^{3/4}\times \frac{50}{0.5}^{1/2}
ΔT = 7.07 A ......................2
and
ΔT = A \times 150^{1/4} \times 0.1^{3/4}\times \frac{25}{0.3}^{1/2}
ΔT = 5.68 A .......................3
so here percentage change is
percentage change =
percentage change = - 0.196
so that modify temperature is lower than by the 0.196 %
Answer:
M/A = 0.425 g/cm²
Explanation:
<u>Given the following data;</u>
Mass = 192 grams
Dimensions = 7 * 10 inches.
To find the mass per unit area;
First of all, we would determine the area of the lead sheet;
Area = 7 * 10
Area = 70 in²
<u><em>Conversion:</em></u>
1 square inch = 6.452 square centimeters
70 inches = 70 * 6.452 = 451.64 square centimeters
Next, we find the mass per unit area;
M/A = 192/451.64
<em>M/A = 0.425 g/cm²</em>
