Explanation

Standard enthalpy change is measured at a defined pressure of 101 kPa (or 1 bar, according to Testbook.com) and a temperature of 298 K (25°C). 

Explanation

 Angular momentum (L) is defined as the cross product of the position vector (r) of a particle with its linear momentum (p) relative to a chosen origin. 

Explanation

The correct unit of the rate constant for a zero-order reaction is mol dm⁻³ s⁻¹ or mol L⁻¹ s⁻¹. 

Explanation

"The form was singing with the clamor of the distinction."

Clamor means: شور مچانا

A loud and confused noise, often from a crowd or chaotic environment.

 Noise بےهنگم آواز   – Best match; clamor refers to loud, often harsh or unpleasant noise.

Explanation

It is the longest distance covered by the object during projectile motion.

When the angle of projection is 45°, the maximum horizontal range is obtained.

Explanation

Molarity is calculated by dividing the number of moles of solute by the volume of solution in liters. 

Therefore, the molarity of pure water is approximately 55.56 moles/L, or approximately 55.5 M. 

Explanation

The dot product of a vector with itself is equal to the square of its magnitude, or |A|².

The dot product of two vectors A and B is defined as: A · B = |A| |B| cos θ, where θ is the angle between the vectors.

When a vector is dotted with itself, the angle θ becomes 0 (since the vectors are parallel), and cos 0 = 1.

Therefore, A · A = |A| |A| cos 0 = |A|². 

Explanation

73.650 rounded up to one decimal place is 73.7.

When rounding up, if the digit to the right of the desired decimal place is 5 or greater,

You increase the digit in the desired decimal place by one.

Since 5 in the hundredth place is greater than or equal to 5, the tenths place digit (6) is increased to 7.

Explanation

Angular acceleration is produced by torque.

Torque is the rotational equivalent of force.

And just as force causes linear acceleration, torque causes angular acceleration. 

Explanation

The slope of a velocity-time graph gives the rate of change of velocity, which is acceleration.

At any instant, this slope shows the instantaneous acceleration.
