Explanation

Pharaoh is correct spelling word.

Pharaoh means فرعون

Explanation

The correct rate equation for the hypothetical reaction aA + bB → cC + dD is Rate = k[A]^a[B]^b.

This equation indicates that the rate of reaction depends on the concentrations of reactants A and B raised to the power of their respective stoichiometric coefficients.

Explanation

Enzyme NADP reductase is responsible for reducing NADP⁺.

It catalyzes the transfer of electrons to NADP⁺, forming NADPH, which is used in the Calvin cycle for carbon fixation.

Explanation

Oxytocin is the hormone responsible for labor pains in human females at the time of birth.

It stimulates uterine contractions, helping in the delivery process.

Explanation

The posterior lobe of the pituitary produces Antidiuretic Hormone (ADH).

ADH helps regulate water balance in the body by controlling the amount of water reabsorbed by the kidneys.

Explanation

In transverse waves, the portion above the mean level is called wave crest.

The crest represents the highest point of the wave, while the trough is the lowest point below the mean level.

Explanation

Angular velocity (ω) is defined as the rate of change of angular displacement (θ) with respect to time (t). It can be calculated using the formula:

ω = v / r

Where:

v = linear velocity (in m/s)

r = radius of the circle (in m)

Given:

v = 250 m/s (linear velocity)

r = 100 m (radius of the circle)

ω = v / r

= 250 m/s / 100 m

= 2.5 rad/s

So, the angular velocity of the aircraft is 2.5 rad/sec.

Explanation

The difference of lithium from the other alkali metals is mainly because of small radius and high charge density.

Lithium has a smaller atomic radius compared to other alkali metals.

This resulting in a higher charge density that leads to stronger ionic interactions and unique chemical properties.

Explanation

The correct ideal gas equation is PV = nRT.

Where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin.

This equation relates these properties for an ideal gas under various conditions.

Explanation

The number of moles is directly proportional to the mass of an element.

It is calculated by dividing the mass of the element by its molar mass.
