Explanation

Creativity involves producing ideas or products that are both original and useful/adaptive.

It reflects innovative thinking and problem-solving skills.

Explanation

The relation between work (W) done and torque (τ) in rotational motion is:

W = τdθ

Where:

- W is the work done

- τ is the torque

- dθ is the angular displacement

This shows that work done in rotational motion is the product of torque and angular displacement.

Explanation

Combustible means آتش گیر

Flammable means آتش گیر

Explanation

Smash up means توڑ

Damage means نقصان

Explanation

Pressure P = F/A. The uncertainty in P is given by:

(ΔP/P) = (ΔF/F) + (ΔA/A)

Given ΔF/F = 2% and ΔA/A = 5%,

(ΔP/P) = 2% + 5% = 7%

Explanation

The microscopic form of Ohm's law is:

J = σE

where J is the current density.

σ is the conductivity.

E is the electric field.

Explanation

Active learning involves students engaging in problem-solving, critical thinking, and application of knowledge.

It goes beyond passive listening, making learning more interactive and effective.

Explanation

The relation between alpha (α) and beta (β) is given by:

β = α / (1 - α)

Given α = 1/2:

β = (1/2) / (1 - 1/2)

= (1/2) / (1/2)

= 1

Explanation

The relation between the coefficient of volume expansion (γ) and the coefficient of linear expansion (α) is: γ = 3α

This relation holds true for isotropic solids.

The coefficient of volume expansion is approximately three times the coefficient of linear expansion.

Explanation

A matrix has an inverse only if its determinant is non-zero, meaning it is non-singular.

Singular matrices (with determinant = 0) do not have an inverse.
