Empty grocery cart runs faster than the loaded one.

By Newton's second law ( law of Acceleration ) :

\(\qquad \sf  \dashrightarrow \: F = ma \)

If the mass is less, less force will be exerted to move it. hence empty cart runs faster than full cart as it requires more force.

Using Seatbelt to hold your body from leaning forward when a car you are riding suddenly stops.

By Newton's first law ( law of inertia ) :

" An object has tendency to resist change in its state until any external unbalanced force is applied on it. "

So, while driving our state is in motion, and when we apply brake, it's change of state from motion to rest, hence by law of inertia, our body still keep up in motion, that makes us to lean forward.

While rowing a boat,paddling will cause the bat to moved forward.

By Newton's third law ( law of enteraction ) :

" Every action has an equal and opposite reaction "

when we paddle, we push (apply force on) the water backwards, and hence water exerts a force on us in forward direction that let us move accordingly in water.

A biker slightly presses the brake as his bike travels down on a slope.

By Newton's second law ( law of Acceleration ) :

\(\qquad \sf  \dashrightarrow \: F = ma \)

A biker applies brake when it's a slope, because it's acceleration increases significantly when it goes down the slope and to maintain the speed he applies a brake to slow down. ( increase in Acceleration causes bike to move fast, as more force is exerted )

lt is easier for you to move a box with relief goods when helped by friends than moving it all by yourself.

By Newton's second law ( law of Acceleration ) :

\(\qquad \sf  \dashrightarrow \: F = ma \)

By the given formula we can clearly conclude that, to move a bulky object ( having heavy mass ), greater force is required, so we call for help as we can easily increase the force when there's more than one person pushing it.

A toy truck with loads runs slower compared to a toy truck with empty loads when you pushed them at the same time.

By Newton's second law ( law of Acceleration ) :

\(\qquad \sf  \dashrightarrow \: F = ma \)

If same force is exerted on heavy and light object, Acceleration of that of lighter body will be more than that of bulky body, so.. the truck with load on it has more mass than truck with no load, hence truck with load moves slower.

A kid catches a flying boomerang and stopping its motion.

By Newton's first law ( law of inertia ) :

" An object has tendency to resist change in its state until any external unbalanced force is applied on it. "

When the kid catches the boomerang it was in motion, so it resists to come at rest, Therefore we need to apply a force and with time it comes to rest.

Your hand hurts when you punch someone hard.

By Newton's third law ( law of enteraction ) :

" Every action has an equal and opposite reaction "

As we hit something hard, it feels painful because when we apply force on that hard object it applies the same force on our palm that results in pain.

Rocket propulsion or when rocket lifts off from a shuttle System.

By Newton's third law ( law of enteraction ) :

" Every action has an equal and opposite reaction "

In order to go up in the sky, one rocket applies a force download by the process of propulsion and hence by Newton's third law, a force of same magnitude is applied on it that cause Rocket to lift up.

A cart at rest start moving once someone pushes it forward.

By Newton's second law ( law of Acceleration ) :

\(\qquad \sf  \dashrightarrow \: F = ma \)

Acceleration in a body is caused by force acting on it, so to move a car ( Accelerate ) we push it forward ( apply force ).

The dirty (modify) bit identifies: a page that has been modified since it was loaded since it was loaded into memory. Therefore, option D is correct.

The dirty bit, also known as the modify bit, is a flag that is associated with each page in a computer's memory management system. It is used to indicate whether a particular page has been modified (changed) since it was loaded into memory.

When a page is initially loaded into memory from secondary storage (such as a hard disk), the dirty bit is set to 0, indicating that the page is clean and has not been modified. However, when the contents of the page are modified by a process or program, the dirty bit is set to 1, indicating that the page has been modified.

The dirty bit is important for various memory management operations, such as page replacement algorithms and write-back policies. For example, when a page needs to be evicted from memory to make space for a new page, the operating system checks the dirty bit. If the dirty bit is set (1), it means that the page has been modified, and its contents need to be written back to secondary storage before it can be replaced. If the dirty bit is not set (0), it means that the page is clean, and it can be replaced without the need for writing it back.

The dirty (modify) bit is used to indicate whether a page has been modified since it was loaded into memory. It plays a crucial role in memory management operations, enabling efficient page replacement and write-back policies.

In the realm of programming-language development during the 1970s and 1980s, several notable figures left a lasting impact. Bjarne Stroustrup ushered in the 1980s by introducing the C++ programming language, an extension of C that brought object-oriented principles to the forefront. John McCarthy's contributions were marked by his creation of LISP, a language pivotal for artificial intelligence research and symbolic processing.

Meanwhile, Niklaus Wirth's innovation lay in Pascal, a language designed with pedagogy in mind, facilitating programming education. However, the claim of Bill Gates and Paul Allen released the first programming language for personal computers is inaccurate, as their pivotal role was in software and operating systems, not language development.

There are 256 different 9-bit strings that contain 5 or more 1's.

The question is asking for the number of 9-bit strings (sequences of 9 binary digits) that contain 5 or more 1's.

To solve this, we can consider the different cases:

1. Count the number of 9-bit strings with exactly 5, 6, 7, 8, or 9 1's individually.

2. Sum up the counts from each case to get the total number of strings that satisfy the condition.

For the first case, the number of ways to choose 5 positions out of 9 for the 1's is given by the binomial coefficient "9 choose 5," which can be calculated as C(9, 5) = 126.

Similarly, for the second case, we have C(9, 6) = 84, for the third case, C(9, 7) = 36, for the fourth case, C(9, 8) = 9, and for the fifth case, C(9, 9) = 1.

Now, we sum up the counts: 126 + 84 + 36 + 9 + 1 = 256.

Therefore, there are 256 different 9-bit strings that contain 5 or more 1's.
