The guidelines for making good and accurate observations are:
1. Standardise the experimental setup: Know the precision and the accuracy of the instrument used to make observations. Example, thermometer with a least count of 1°C cannot measure in fractional values.
2.Take careful measurements: Holding the instrument properly without causing any disturbance is the key.
Answer:
The third diagram shows Refraction of waves.
Explanation:
Refraction is a phenomenon, which occurs in a wave when it travels from one medium to another medium, and during Refraction there is slight or greater change in direction of the wave.
hence, the wave will pass through the surface and displaces from its actual path.
that's why the most appropriate diagram showing Refraction is third one ( c ) .
Maybe you can do something like a self operating beaker that does all the measuring, pouring, and mixing for you. If that’s not interesting enough you can make it talk too, like a robot. Hope this helps!
Answer:
The cognitive abilities of an individual to learn from experience, to reason well, and to cope effectively with the demands of daily living
Explanation:
Intelligence is something that can actually be measured, even though it is not a physical, but a psychological trait. The humans had wanted to be able to measure their intelligence for quite some time, but that only became possible with the development of the modern psychology and the test specially created for this purpose. The intelligence represents the cognitive abilities of an individual to learn from experiences, how well can it reason, as well as to cope effectively with the demands of the daily living. To put it more simple, it is the ability of an individual to acquire and apply skills and knowledge in its life.
