Why we cannt cook food on high attitude (like mountain where exist low temperatures )? ​

Cooking takes longer because water and other liquids evaporate faster and boil at lower temperatures.At sea level water boils at 212degrees Fahrenheit but at an altitude of 7,500 feet, it boils at about 198 degrees. Foods that are prepared by boiling or simmering will cook at a lower temperature and it will take longer to cook them. Hope this helps!! ; )

Why does the sky appears blue? ​
SashulF [63]

A 0.270 m radius, 510-turn coil is rotated one-fourth of a revolution in 4.17 ms, originally having its plane perpendicular to a
vlada-n [284]

Answer:

0.35701 T

Explanation:

B_i = Initial magnetic field

B_f = Final magnetic field

\phi = Magnetic flux

t = Time taken = 4.17 ms

N = Number of turns = 510

\epsilon = Induced emf = 10000 V

r = Radius = 0.27 m

A = Area = \pi r^2

Induced emf is given by

\epsilon=-N\frac{d\phi}{dt}\\\Rightarrow \epsilon=-N\frac{B_fAcos90-B_iAcos0}{dt}\\\Rightarrow \epsilon=N\frac{B_iA}{dt}\\\Rightarrow B_i=\frac{\epsilon dt}{NA}\\\Rightarrow B_i=\frac{10000 \times 4.17\times 10^{-3}}{510\times \pi 0.27^2}\\\Rightarrow B_i=0.35701\ T

The magnetic field strength needed is 0.35701 T
