High pressure decreases the amplitude of atomic vibrations. This causes :

The size of the trivalent cations in the lanthanoid series decrease steadily as the atomic number increases. What is this known as ?

Statement 1. The process of changing the amplitude of a carrier wave in accordance with the amplitude with the basic voice frequency (VF) or audio signal (AF) is known as amplitude modulation (A.M.) Statement 2. Modulation is the process of variation of some characteristic of a high frequency wave any manner.

The cause of the fractional atomic weight of elements is

At constant temperature , if pressure increases by 1% , the percentage decrease of volume is :

Assertion (A): The increasing pressure on water decreases its freezing point. Reason (R ):The density of water is maximum at 273 K .

For the equilibrium system. N_(2)(g)+O_(2)(g)+ Heat hArr 2NO(g) Which of the following factors would cause the value of equilibrium constant to decrease ?

[A] : Hair cells on the basiiar membrane are responsible for hearing. [R]: Pressure waves which begin at the oval window, cause the basilar membrane to vibrate so that the cilia of the hair cells touch the tectorial membrane. This causes hair cells to initiate nerve impulses

The net pressure gradient that causes the fluid to filter out of the glomeruli into the capsule is
