Many of today’s mathematicians use computers to test cases that are either too time-consuming or involve too many variables to test manually, allowing the exploration of theoretical issues that were impossible to test a generation ago.
Answer: Option A
<u>Explanation:</u>
One of the most useful inventions in scientific world are the computers. We can use different programming language and create programs in them. These programs help other to solve difficult problems. Most of the theoretical problems in science can be solved by using these programming features in computer within a specific time limit.
Otherwise, earlier mathematician used to take months to solve a complex mathematical problem manually, but now with the inclusion of computers, the mathematician can solve the problems containing more number of variables or other theoretical issues.
Answer:
Femur
Explanation:
The bone to forensically analyze in order to create a height profile of the victims would the <u>femur</u>.
The approximate height of a human can best be estimated by measuring the length of the bone that runs from the hip to the knee, otherwise known as the femur.
<em>For the males, the length of the femur in centimeters is multiplied by 2.32 followed by the addition of 65.53 in order to arrive at the approximate height of the individual. For the females, on the other hand, the length of the femur in centimeters is multiplied by 2.47 followed by the addition of 54.1.</em>
Answer:
Explanation:
Person suffering from myopia is unable to see objects beyond 50 cm because far point of his vision is 50 cm . He requires a concave lens
( diverging lens ) to correct his vision .
After using the lens ,
ray of light coming from far off place will appear to be coming from 50 cm after refraction through lens so it will be focused on retina .
object distance u = ∝
image distance v = - 50 cm
focal length f = ?
1 / v - 1 / u = 1 /f
- 1 / 50 - 1 / ∝ = 1 / f
- 1 / 50 = 1 / f
f = - 50 cm
focal length is negative so len is concave.
He requires concave lens of focal length 50 cm .
The atom is neutral because the number of protons is equal to number of electrons in which they cancel the charges of each other and the arom becomes neutral
