Advantages of using scientific methods: You can test in many different ways, and the more times you test, the more accurate your results will be. Disadvantages of using scientific methods: You can come up with different results which can disprove your hypothesis, and this leads to inconsistent conclusions.

It is because most likely you are to have a fair test, it is to ensure that the test was fairly done and that your results aren't due to a "one off" or a change in the experiment. For example in an experiment using rats one experimental rat may be different to the other rat like be abnormal or slightly unusual and therefore you would have an unfair test as the two weren't the same. So you wouldn't get a correct measurement or end result.
Invitro tests are carried out using cells, enzymes or isolated receptors as target for the substance under test. The advantages include small test sample to be used, no need for ethical consideration and ease of operation which facilitates bioassay guided isolation of active compounds
If rigidity obtained by a torsion test is low, that means that the item is likely to fracture. A torsion test will tell a person how easily something will break.

Hacking is unauthorized use of computer and network resources, it could be remotedly or by directly logging in your PC advantages: hacking tools are used to test the security of a network, pc etc. disadvantages: is being used by criminals to steal information and passwords
Yes.Modulus of RuptureUltimate strength determined in a flexure or torsion test. In a flexure test, modulus of rupture in bending is the maximum fiber stress at failure. In a torsion test, modulus of rupture in torsion is the maximum shear stress in the extreme fiber of a circular member at failure. Alternate terms are flexural strength and torsional strength.
Advantages are that you don't have to have the baby growing inside you for almost a year, and you don't have to force it out of your snatch at birth. Disadvantages are that you need a series of ever-bigger test tubes which are really expensive (although if you can afford a baby you must be rolling in spare cash anyway!), and they're easy to break, especially as you have to keep them out of direct sunlight
Torsion refers to twisting.Example: Different materials like metal are tested to their breaking point by:PullingBendingTwisting
A pre-test and post-test loop allows for effective evaluation of changes in a process or program by measuring outcomes before and after an intervention. Advantages include the ability to assess the impact of changes and improve decision-making based on data. However, disadvantages may include potential biases if the testing conditions change between tests, and the possibility of participants altering their behavior due to awareness of being tested. Additionally, it can be resource-intensive, requiring careful planning and execution.
the formula of B.H.N is give less accurate value when the indentation is more. It has only one scale And applied only to some materials.
