Explanation

The mitochondrion is the organelle responsible for ATP production, often called the "powerhouse of the cell"

It generates most of the chemical energy needed to power a cell's biochemical reactions.

Through a process called cellular respiration,

Mitochondria convert glucose and other molecules into ATP, the cell's main energy-carrying molecule. 

Explanation

Average speed = Total distance ÷ Total time  

= 150 km ÷ 3 hours  

= 50 km/h

Explanation

The acceleration of a rolling object is zero at the highest point of the hill,

Or the point where its upward motion stops, and before it begins to roll back down.

At this specific moment, the object is momentarily at rest,

But its acceleration due to gravity is still acting on it. 

Explanation

Profit = 28500 - 25000 = 3500  

Profit% = (3500/25000) × 100 = 14%

Explanation

The Green Revolution was introduced during Ayub Khan’s era in the 1960s.

It was based on the introduction of the US helping Pakistan with economic Aid for Pakistan

Explanation

 20 ÷ (5 - 3) × 2

= 20 ÷ 2 × 2

= 10 × 2

= 20

Explanation

 A stopwatch that measures time to the 1/100 second is called a digital stopwatch or digital chronograph.

These electronic devices offer greater precision than traditional mechanical stopwatches
Which typically only measure to 1/10th of a second. 

Explanation

 A = 1, H = 1 → A + 2 = 7 → A = 5  

If Z = 26, O = 15 → Z - O = 26 - 15 = 11

Explanation

Movement along a circular path = Circular motion.

This type of motion can be uniform (constant speed) or non-uniform (changing speed),

And it always involves a continuously changing velocity due to the changing direction of the object, even if the speed remains constant. 

Explanation

A moving object is in equilibrium if it moves with a constant velocity; then its acceleration is zero.

A zero acceleration is the fundamental characteristic of an object in equilibrium.
