When do you use applied research?
Applied research tries to solve a particular problem. Like how can we make a better widget? Research funds are allocated and the scientists are usually expected to have an answer by the end of the project and are often expected to show a profit. Pure research is science for just finding something new without knowing what that will be. The Hubble space telescope is a good example of that. Pure research leads to new discoveries. Applied research tries to make practical uses for some of those discoveries. Pure research discovered something called Giant magneto resistance applied research turned that discovery into a hard disc drive that can hold thousands of songs, movies and pictures. * Is conducted in relation to actual problems and under the conditions in which they are found in practice; * Employs methodology that is not as rigorous as that of basic research; * Yields findings that can be evaluated in terms of local applicability and not in terms of universal validity.
What does a catapult consist of and what math is needed?
A catapult is a mechanical device that can be used to project a projectile. There are several different designs. The device is "charged" by either stretching an elastic material or by putting a beam under a bending tension. This stores up potential energy in the machine. The catapult is then fired by releasing this energy instantly. The mathematical required are:calculation of tension in the elastic band or bent beam,impulse imparted to the projectile,trajectory of projectile travelling under the influence of the force of gravity.At school, it is usually assumed that air resistance can be ignored.
Have a look at how many primes there are up to 10 20 30 40 and so on until 100. Describe what you notice?
There are 4 under 10 8 under 20 10 under 30 12 under 40 15 under 50 17 under 60 19 under 70 22 under 80 24 under 90 25 under 100 The frequency of primes decreases as the numbers increase.
How many prime numbers are there under 1000?
