Explanation

To find the angle in radians per second, first convert the rpm (revolutions per minute) to radians per second.

3000 rpm =  3000/60 ​revolutions per second =  50 revolutions per second.

Each revolution is  2π radians.

So, 

50×2π=100π radians per second.

Explanation

According to Newton's second law, 

F=ma, a constant non-zero force results in uniform acceleration of the mass.

Explanation

The vector product (cross product) of two vectors gives a vector that is perpendicular to both original vectors.

Angular momentum is a vector product of position and linear momentum vectors.

Explanation

Energy and work have the same dimensional formula, $$[ML2T−2][ML^2T^{-2}]

Both represent the ability to perform work or cause a change in energy.

Explanation

PbCl₂ (lead(II) chloride) is ionic.

Lead(II) chloride forms an ionic lattice structure with chloride ions,

while PbCl₄ is a covalent complex.

Explanation

Cilia and flagella have a characteristic "9+2" arrangement of microtubules: nine outer pairs and two central single tubules.

Explanation

The selective permeability of a membrane is primarily due to its lipid bilayer and the embedded proteins.

Lipids form the basic structure of the membrane, while proteins play roles in transport and signaling.

Explanation

The smooth endoplasmic reticulum (SER) is involved in the synthesis of lipids, including phospholipids and steroids.

Explanation

The glyoxisome is a single-membrane organelle.

In contrast, the endoplasmic reticulum, Golgi apparatus, and mitochondria all have double membranes.

Explanation

Maltose is a disaccharide consisting of two glucose units linked by an α-1,4 glycosidic bond.
