Why is the value of G 9. 8 m s2?.
Answer:
the acceleration due to gravity on earth or the value of g on earth is 9.8.
Laura is riding her bike at a speed of 15 m/s when she spots a dog in his path. If she needs to come to a full stop in 3 seconds what must her deceleration be?
The deceleration of Laura is obtained as - 5m/s^2.
What is the deceleration?We know that the deceleration would have to be the rate of the decrease in the speed of the object with time. We would use the formula for the acceleration to be able to obtain the deceleration of the object as follows;
a = v - u/t
a = deceleration
v = final velocity
u = initial velocity
t = time taken
Then;
a = 0 - 15/3
a = - 5m/s^2
Thus she would have a deceleration of - 5m/s^2 from the calculation that we have done above.

What happens when two forces are parallel?.
Two parallel forces that are equal in strength, sense-opposite, and do not share an action path make comprise a couple force. Only rotation is produced; there is no translation. A couple's resulting force is zero.
What outcome may two parallel pressures produce?Two parallel forces may be moving in the same direction or in opposition to one another. Two forces combine when they move in the same direction. Balanced forces are two equal forces acting in opposition to one another. Couple: A couple is a pair of opposing, parallel, equal forces that have lines of action that are parallel to one another and act in different directions. When two forces engage in opposition to one another, the lesser force is subtracted from the larger force to form the combined force. The direction of the larger original force is the direction of the generated force (resultant).

What is force multiplied by distance?.
Force multiplied by distance is nothing but work done. It can also be described as work done is the dot product of force and distance.
A force is a quantity which is a vector because it has both a magnitude and a direction. According to Newton's laws, the force acting on an item is what causes it to move or cease moving.
Force multiplied by distance equals work. Work is a form of energy that is expended as an object moves along certain distance. However, note that this particular formulation:
W = F d
The above equation works only if force is constant and if the movement is entirely linear on a flat surface. General formula for determining work can be done through calculus as:
W = ∫ F ds
where the distance becomes differential from d to ds, and allows us to evaluate the work done even for non-linear paths or on paths that are inclined at angles above the horizontal plane.

How many Newton laws are there?.
There are three laws of motion described by Sir Isaac Newton. These laws describe the behavior of objects in motion and form the foundation of classical mechanics. The laws are as follows:
1. The first law states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity unless acted upon by an external force. This is often referred to as the law of inertia.
2. The second law states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. The acceleration of an object is given by the equation F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.
3. The third law states that for every action, there is an equal and opposite reaction. This means that if an object exerts a force on another object, the second object will exert an equal and opposite force on the first object.

Does more bandwidth reduce latency?.
Yes, more bandwidth reduce latency.
Bandwidth reduces latency because there is a wider pipeline through which more data passes, reducing the chance of data packets being delayed. On the other hand, high latency can create bottlenecks and reduce effective bandwidth, at least until the delayed data packets get through.
Maximum amount of data sent over an Internet connection in a given period of time. Bandwidth is often confused with internet speed. It is actually the amount of information that can be transmitted over a connection in a given amount of time, calculated in megabits per second (Mbps) or wireless communication links for transmitting data over network connections.

How does edge computing improve application performance?.
By moving processing and data storage closer to the edge of the network, where the data is created and utilized, edge computing increases application performance.
How edge computing improves the performance of applications:
Applications become quicker and more responsive as a consequence of first reducing the latency and bandwidth problems related to transmitting data to and from centralized data centers or cloud servers.
Edge computing lowers latency by reducing the quantity of data that has to be transferred over the network by processing data close to the edge of the network. This is because data can be processed and evaluated more quickly and locally rather than having to travel as far.
Applications are more dependable and robust when they can operate offline or with restricted connection thanks to edge computing. This is due to the possibility of local data storage and processing, as opposed to depending on a network connection to a centralized data center or cloud server.
Additionally, edge computing enables real-time data processing, which is crucial for applications like autonomous cars, industrial automation, and IoT that call for quick answers.
To summarize, edge computing brings processing and data storage closer to the edge of the network, where data is created and utilized, improving application performance by lowering latency and bandwidth constraints.

What is momentum simple answer?.
Momentum is a measure of an object's motion.
Momentum is the product of an object's mass and velocity, and is represented by the symbol "p." In physics, momentum is considered to be a vector quantity, meaning it has both magnitude and direction.
The basic equation for momentum is p = m*v, where "m" is the object's mass and "v" is its velocity. This equation states that the momentum of an object is directly proportional to its mass and velocity. In other words, an object with a greater mass or a greater velocity will have a greater momentum.
An important concept in physics is that momentum is conserved. This means that in a closed system, the total momentum before a collision or any other interaction is the same as the total momentum after the collision. It also means that the momentum of an object or system of objects cannot be created or destroyed, it can only be transferred or exchanged.
Momentum also plays an important role in many areas of our everyday lives, for example in sports, where a player has to transfer a lot of momentum to hit a ball with a bat. It also plays a role in transportation, where vehicles have to have a certain amount of momentum to move and maintain the velocity.
In summary, momentum is a measure of an object's motion, and it is directly proportional to the mass and velocity of the object. It is a vector quantity and conserved in closed systems. It plays an important role in many areas of physics, and in our everyday lives.
