Answer:
The solution and complete explanation for the above question and mentioned conditions is given below in the attached document.i hope my explanation will help you in understanding this particular question.
Explanation:
The equatorial diameter of the earth is 12,756 km.
Therefore the equatorial radius is
r = 12756/2 = 6378 km.
The angular velocity of the earth is
ω = (2π radians)/(24 hours) = 0.2618 rad/h
The tangential velocity of a person at the equator is
v = rω
= (6378 km)*( 0.2618 rad/h)
= 1670 km/h
Answer: 1670 km/h
I hope this helps you.
Brainly, thanks you, rating are all appreciated greatly!
Smile and have an amazing day ; )
Answer:

Explanation:
Let's use Shockley ideal diode equation which relates the current intensity and the potential difference:

Where:

Thermal voltage at any temperature it is a known constant defined by:

Where:

(a)
Using the data provided:

(b)
Using the data provided and Shockley ideal diode equation

(c) Let's isolate
from Shockley ideal diode equation:


Finally, using the data provided:

Answer:
C) Injection
Explanation:
Injection is a molding process, not a heat transfer mechanism.
Answer:
This is not a clear indication of the hot zone as the information of the radioactivity of the background is not provided clearly.
Explanation:
According to IAEA as well as NRCP, the hot area is defined on the basis of the radioactivity reading it shows instead of contrast or comparative reading from the background. The value of radiation activity which will be required to declare an area as hot zone is if it is greater than 0.1 mSv/h or
