Timidly means شرم یا خوفزدہ انداز میں کام کرنا ، اعتماد کا فقدان

Fearfully means شرم یا خوفزدہ انداز میں کام کرنا ، اعتماد کا فقدان

Explanation

Na₂CO₃ is the salt that will produce the highest pH when dissolved in water because it is derived from a strong base (NaOH) and a weak acid (H₂CO₃).

Explanation

 Human tissues, particularly in organs like the brain and kidneys, can contain approximately 85% water.

The exact percentage varies by tissue type, but many, especially soft tissues, are largely composed of water.

Explanation

 Half-life definition:

The half-life of a radioactive substance is the time it takes for half of the atoms in a sample to decay. 

This decay process is inherent to the specific nucleus of the atom, meaning the half-life is a property of the substance itself and is independent of factors like the amount present or how old the sample is. 

Explanation

An attribute describes the characteristics or properties of an object or entity (e.g., name, age, color).

It helps define what the object is like.

Explanation

The expression "p implies q" is written as p → q, which means if p is true, then q must also be true.

So, p → q is the correct symbolic form.

Explanation

In the five kingdom classification by Whittaker.

All unicellular prokaryotes like bacteria and cyanobacteria are placed in Kingdom Monera.

These organisms lack a true nucleus and membrane-bound organelles, distinguishing them from other kingdoms.

Explanation

Soft iron is most suitable for transformer cores due to its high magnetic permeability and low hysteresis loss.

It allows efficient magnetic flux linkage, improving transformer performance.

Explanation

A body is in translational equilibrium when the vector sum of all forces acting on it is zero, meaning ∑F = 0.

This implies the sum of forces in both the x and y directions are also zero, i.e., ∑Fx = 0 and ∑Fy = 0.

The statement ∑τ = 0 is related to rotational equilibrium, not translational equilibrium.

The condition ∑β = 0 is not standard terminology in physics.

Explanation

 If matrix A has an order of 3x2, then the order of its transpose (A') will be 2x3.
