How does science affect technology science?

Technology allows science to progress. Technology allows scientists to perform research. Everything around you that was created by man is technology.

Better technology allows scientists to perform wilder and more precise experiments. Then, the results from those experiments often allow for better technology to be made.

In other words improvements in technology gives science better tools with which to discover previously unknown natural phenomena and to better quantify and understand already known natural phenomena.
Technology has a huge role in science most of our discoveries were because we have such great technology to assist us in reaching our goals.

How strong does a laser pointer need to be to cut paper?

Burning paper requires 1 watt (1000 mW), which is more than what most laser pointers can achieve without modifications

For comparison: Popping balloons or lighting matches requires roughly 100 mW (which is the high end mW range of most commonly found laser pointers)

Note: laser pointers anywhere near 100 mW and up are very dangerous to the eyes and can cause permanent degrading of vision (some doctors say any laser above 5 mW can cause eye damage), so use with caution and never point at anyone's face

What does industrial robot mean?

An industrial robot is designed to work- to build things. You see in car factories how the arms are putting the cars together- that is an industrial robot. They are programmed to make certain moves and perform certain tasks.

What will happen if a diode is connected to capacitor?

the diode when forward biased will conduct

and during reverse biased condition(generally doring reverse biased condition ckt is open mens no current flows;when register is connected)current flows

but during reverse biased condition

1--for sometimes initially current flows due to discharging of capacitor.

2--then ckt will be having no current

Do radio frequency devices cause headaches?

No, not under normal circumstances do RF devices cause headaches. Radio frequencies are all around you at any given moment in time. Standard devices that you use everyday such as a radio (car, home, or walkman) or cordless phone pick up and use these radio transmissions.

What is the difference between process and procedure?

There are a number of procedures within a process. A process requries a set of procedures. It means that you take actions to get results. The actions you take are your set of procedures (ISO). Procedures / actions / activities / work instructions all describe the lowest level of decomposition ie: the procedure cannot be broken down further.

-- These terms can be defined differently in terms of different scenario. In a Quality perspective, Process is the set of action items to achieve the work completion and procedure is further decomposition of process to ensure the quality.

In boiling it all down, I have found that the best means of comparison is this: A Process defines what is to be done, and a Procedure describes how (the steps involved) the activities of the process are to be performed. A good illustration would be that an organization has to define, for example, the process of software testing. In so doing, there are inputs (Requirements), activities (Test Planning and Execution) and outputs (Test Analysis Report). The objective of the process model is to show that an organization is meeting the generally prescribed testing activities in addition to performing adequate planning, review and approval along the way. Once the process has been accepted, the organization will then drill into each of the activities on the process diagram and annotate the actual steps (procedures) that will reflect the activity and produce the desired output.
