What is dynamics lift?

In a p-n junction diode, the current I can be expressed as I = I_0 exp ((eV)/(2k_BT)) where I_0 is called the reverse saturation current, V is the voltage across the diode and is positive for forward bias and negative for reverse bias, and I is the current through the diode, k_B is th Boltzmann constant (8.6xx 10^-5 (eV)/K) and T is the absolute temperature. If for a given diode I_0 = 5 xx 10^-12 A and T = 300 K, then - What is the dynamic resistance when the voltage is increased to 0.7 V from 0.6 V?

Biological classification is a dynamic and ever evolving phenomenon which keeps changing with our understanding of life forms. Justify the statement taking any two examples.

What is particle dynamics?

Define the term dynamic resistance of a p-n junction diode.

STATEMENT-1: The physical equilibrium is not static but dynamic in nature. STATEMENT-2: The pysical equilibrium is a state in which two opposing process are proceeding at the same rate.

In a test experiment on a model aeroplane in a wind tunnel, the flow speeds on the upper and lower surfaces of the wing are 70 m s^-1 and 63 m s^-1 respectively. What is the lift on the wing if its area is 2.5 m^2 ? Take the density of air to be 1.3 kg m^-3
