Explanation

• The adverb form of "simple" is "simply".
• It means in a straightforward or easy manner.

Explanation

Reported speech requires past perfect for an action completed earlier.

Correct sentence: “Ahmed said that his friends had betrayed him.”

Explanation

Explanation

With is a preposition here.

We generally use with before influence.

He got the job with influence اس نے اثر و رسوخ سے کام حاصل کیا

Explanation

A scalar quantity only has magnitude (a numerical value) and no direction.

Speed is the magnitude of velocity,

Which means it tells you how fast something is moving without considering its direction. 

a) Velocity:

Velocity is a vector quantity because it has both magnitude (speed) and direction. 

b) Acceleration:

Acceleration is also a vector quantity as it describes the rate of change of velocity,

which means it needs both magnitude and direction to be fully defined. 

d) Force:

Force is a vector quantity as it has both magnitude (how strong the push or pull is) and direction. 

Explanation

- Potential difference (V) is the work done per unit charge to move a charge between two points.  

- Formula: V = W/Q  

  (where W = work in joules, Q = charge in coulombs)  

- 1 Volt = 1 Joule / 1 Coulomb  

- It tells us how much energy is used to move electric charges through a circuit.

Explanation

Bernoulli's equation is derived under the following assumptions:

- A) Steady flow  (Flow parameters do not change with time)  

- B) Incompressible fluid  (Density remains constant)  

- C) No external forces acting on the fluid. Incorrect assumption  

   → Bernoulli’s equation does consider external forces like gravity (included as potential energy).  

- D) Negligible viscosity  (No energy loss due to internal friction)

Thus, option C is not assumed and is the correct answer.
