What is shift of the maximum spectral density of radiosity at the changing human body surface temperature from t1= 30°C to t2= 31°C? Нuman body to consider as grey. Wien's constant b=2898 um*K.

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.
