Summary:
Ergonomics can be used to improve a student’s ability to focus on learning for say, when writing a long essay. Ergonomics helps with keeping the wrists comfortable with an ergonomic writing utensil and not straining the back with a comfortable sitting position. It helps with eye strain, keeping students at a comfortable distance from the board. And it reduces distractions to improve focus.
Longer version:
Sitting posture is a very important ergonomic factor which could influence a student's focus. Bad sitting posture could be caused by the height of chair and the desk position. Bad sitting posture often affects a child's level of attention or focus. Hence, choosing a an appropriate table and chair combination for different height measures should be considered. The distance between students and the lecture board should be considered as students have varying preferences. Hence, taking note of a comfortable distance for each student is an important concept. The removal of distractive elements in the classroom environment is also an ergonomic concept which could improve focus. Therefore, the concept of ergonomics applied in classroom environment could help improve student's focus.
Answer: Comfortable Furniture, Lighting, Reduced Noise, Correct Posture.
Explanation:
In My opion Ergonomics can be used significantly in the classroom environment to improve a student's ability to focus on learning in the following ways;
Comfortable furniture: By providing comfortable furniture such as desks, chairs, and tables, the students will be able to focus on learning for a more extended period.
Lighting: Adequate lighting in the classroom is essential for students as it can prevent eye strain and headaches.
Reduced noise: An environment with reduced noise will help students concentrate better on their studies.
Correct posture: Ergonomics can be used to promote the right posture among students while studying. Poor posture can cause health issues such as backaches and neck pain, which can negatively affect a student's ability to focus on learning.
In conclusion, ergonomics can significantly improve a student's ability to focus on learning by providing comfortable furniture, adequate lighting, reduced noise, and promoting correct posture.
Crude oil at 20 c fills the space between two concentric cylinders 250 mm high and with diameters of 150 mm and 156 mm. Find the torque is required to rotate the inner cylinder at 12 r min, the outer cylinder rernaining stationary
the torque is required to rotate the inner cylinder at 12 r min, the outer cylinder remaining stationary is 11.0807 N-m.
we have left out some other important details, such as the time required to reach that rpm, whether the beginning state is at rest, and the axis around which the cylinder is revolving. However, we'll suppose that it will be 60 seconds (time is necessary to convert rpm to angular acceleration)
rotation around the center axis
Angular acceleration = torque + MOI
Currently, angular acceleration equals 2 rpm/(t 60).
In order to avoid getting an extremely high figure, we estimated that the diameter of the cylinder was 600 mm rather than 600 meters: angular acceleration= 1.047 rad/s² MOI for cylinder across center dia= 1/4MR²+ 1/12ML²
MOI= 10.5833 kg-m
Now, the product of these two is torque.
11.0807 N-m of torque
Various MOI equations can be used to compute for different axes of rotation.

If current flowing through a conductor is 10 mA. how many electrons travel through it in 10 s?
6.25×10⁻¹⁸ electrons will flow through a copper wire.
What are electrons?Electrons can be defined as the sum of atomic particles that is the career of negative charge, they are responsible for the chemical property of an element, the electrons are present in the shell.
Use formula ( I = ne/t )
Here,
number of electron
electron =1.6 x 10¯¹9 C
We have a relation between charge and current as
Charge = Current×time i.e
Q = i×t.
Now we have current = 10 amp & time = 10sec from given data.
Therefore charge Q = 10×1 = 100 coulombs.
Again we have a relation between charge and no of electrons
I.e no of electrons= total charge / 1.6×10⁻¹⁹
So, no of electrons = ( 100C/1.6×10⁻¹⁸ )
= 6.25×10⁻¹⁸ electrons.
Therefore, 6.25×10⁻¹⁸ electrons will flow through a copper wire carrying 10 amps current for 10 sec

Tech a says that a brake-by-wire system can start to apply brakes before the driver can step on the brake pedal. tech b says that brake-by-wire systems use heavy cables to transmit the brake pedal force to the wheel brake units. who is correct?
A brake-by-wire technology, according to Tech A, applies individual braking units to each wheel.
There are three different types of brake-by-wire technologies being used in the automotive industry to advance braking systems: electro-hydraulic, entirely electric, and a hybrid of the two. A brake booster is not required thanks to the electro-hydraulic system. Although there aren't any entirely drive-by-wire production cars yet, several car makers have created concept cars that satisfy the bill. To put it another way, a drive-by-wire system uses an electrical signal to instruct the engine on how much power to produce. The latter (drive-by-cable) still transmits data from the accelerator pedal to the engine through a mechanical cable.

Is annealed polycrystalline copper a material that work hardens significantly or a material that exhibits a low work-hardening rate
Those that harden under strain, such as the aluminum-magnesium alloys used in beverage cans and the copper-zinc alloy, brass, used for cartridges, which show more strain hardening than pure copper or aluminum, respectively.
When a material is deformed under a substantial amount of strain, strain hardening is seen as a strengthening process. Lamellar crystals and chain molecule orientation on a vast scale are the culprits. When plastic materials are stretched past their yield point, this phenomena is frequently seen. When a metal is stretched past its yield point, strain hardening occurs. The metal appears to get stronger and harder to deform as more stress is needed to cause additional plastic deformation. Strain hardening is directly related to fatigue.

Consider an incandescent lightbulb. If you wanted to turn a 10-w lightbulb into a 100-w lightbulb, how would you change the temperature of the filament inside the bulb?.
The temperature of the filament within the lightbulb can be altered by a factor of 10²⁵ by applying the blackbody radiation formula.
To tackle this issue, we need to understand black body radiation. A black body object's energy emission is inversely proportional to its area and the temperature to the fourth power. It can be calculated using the formula P = A e. T4, where is Stefan Boltzmann's constant (5.67x10⁸W/m/2K4), P is power, A is surface area, e is emissivity, and A is surface area.
We can deduct from the previous query that P1 = 10 watts and P2 = 100 watts.
The temperature ratio is T14/T24 = P1/P2 according to the black body radiation formula, which means that T2 = (T1*10⁴)/4
T2=T1 x 100²⁵.
As a result, the filament's internal temperature is altered by a factor of 10²⁵.

It is comparable to engineering notation. In this case, x is in the range of 0 to 1000, and the exponent n is the biggest multiple of 3 such that 10ⁿ is less than the integer. As a result, the responses are in the form x10ⁿ. For example, 53.476*10³ is used to symbolize the number. This makes it easy to add prefixes like micro, mili, mega, or kilo in front of the unit right away. The significand has exactly one digit before the decimal point in scientific notation.
