With so many people using electricity on a daily basis—whether it is to charge their cell phones or to use their TV—a lot of cables (made of plastic) must be used. Plastic destroys our ecosystem, yet we continue to produce it. Indispensable as it may seem, it has an adverse effect on the environment. The manufacturing of plastic is not exactly ecofriendly. With a little help from modern technology Elif discovered a way to help curb our plastic problem. She used banana peels as the main ingredient to make bio-plastics. Which of the Sustainable Development Goal does this scenario relate to? a) Life on land b) Responsible consumption, and production c) Affordable and clean energy d) Sustainable cities and communities

Air pollution kills an estimated seven million people worldwide every year. WHO data shows that 9 out of 10 people breathe toxic air. From smog hanging over cities to smoke inside the home, air pollution poses a major threat to human health and climate. The major pollution sources include vehicles, power generation, agriculture/ waste incineration, and industry. Harmful gases like SO2, NO2, CO are emitted directly into air because of pollution. Deploying an air quality index monitor is one way that would help to know the local air quality and take action to protect their health. Taking this as the problem, choose which of the following would be the ideal problem statement template. a) Our WHO have a problem that people breathe toxic air when smog hangs over cities. An ideal solution would be to shut down industries and stop the movement of vehicles in major cities. b) Our people have a problem that they die in accidents when more number of vehicles are used. An ideal solution would be to develop be to stop the movement of vehicles in major cities. c) Our people have a problem that air pollution has damaging effects on human health when harmful gases like SO2, NO2, CO are emitted directly into air. An ideal solution would be to develop an air quality index monitor so that one can know the local air quality and take action to protect their health. d) Our WHO have a problem that people die every year when there is an increase in the number of vehicles and industries. An ideal solution would be to make sure people stay indoors to protect their health.

In `R-L-C` series circuit, we have same current at angular frequencies `omega_(1)` and `omega_(2)`. The resonant frequency of circuit isA. `[omega_(1)omega_(2)]^(1//2)`B. `(omega_(1)+omega_(2))/(2)`C. `(omega_(1)omega_(2))/(omega_(1)+omega_(2))`D. None

Answer» Correct Answer - A
`Z_(1)=Z_(2),sqrt(R^(2)+(X_(C )-X_(L))^(2))` = same
`(X_(C)-X_(L))^(2)` =same
`((1)/(omega_(1)C)-omega_(1)L)=-((1)/(omega,C)-omega_(2)L),(1)/(C )((1)/(omega_(1))+(1)/(omega_(2)))=L(omega_(1)+omega_(2)),(1)/(sqrt(LC))=sqrt(omega_(1)omega_(2))`

For the ideal RL circuit shown, the resistance is `R=10.0Omega`, the inductance is `L=5.0 H` and the battery has voltage `xi_("bat") = 12` volts. Some time after the switch S in the circuit is closed, the ammeter in the circuit reads `0.40A`. If the rate at which energy is being stored by the inductor at this instant is `(16)/(x)` Watts, what is the value of x? A. 3B. 4C. 5D. None of these

Answer» Correct Answer - C
`(dU)/(dt)=(Lidi)/(dt)=i(V_(L))=i(V-V_(R))=0.4(12-0.4xx10)=3.2"Watts"=(16)/(5)"watts"impliesx=5`

The iodide is quantitatively converted to chloride when it is heated in a stream of chlorine. `XI_(3) + 3Cl_(2) rarr XCl_(3) + I_(2)` It 1 gm of `XI_(3)` is converted into `(1)/(3) gm` of `XCl_(3)` then atomic mass of X is :A. `30.75 gm`B. `20.5 gm`C. `61.5 gm`D. `10.25 gm`

Answer» Correct Answer - A
`{:(2XI_(3),+,3Cl_(2),rarr,2XCl_(3),+,3I_(2),),(1 gm,,,,(1)/(3) gm,,,):}`
Let atomic mass of X be M
`n_(XI_(3)) = n_(XCl_(3))`
`(1)/(M + 381) = ((1)/(3))/(M + 106.5)`
`M + 106.5 = (M)/(3) + 127`
`(2M)/(3) = 20.5`
`M = 30.75 gm`

Why do tendrils coil around hard rough objects?

Answer»

The growth movement of tendril in response to unilateral stimulus of touch is called thigmotropism. tendrils of louki, lori, karela, and sweet pea plants coil around hard objects when they come in their contact. It occurs due to unequal growth of two sides of a tendril. The growth of the surface which comes in contact of the support is retarded, while it remains normal or increased on the other side, due to which tendril coils around the support.

Working 5 hours a day, A can complete a piece of work in 8 days and working 6 hours a day, B can complete the same work in 10 days. Working 8 hours a day, they both can complete the work in:1. 4 days2. 5.4 days3. 4.5 days4. 3 days

Answer» Correct Answer - Option 4 : 3 days

Given:

'A' can complete a work in 8 days working 5 hours a day

'B' can complete a work in 10 days working 6 hours a day

Concept used:

If a person works in n days working y hours a day, then

One day work by that person is 1/ny part of total work

Calculation:

One day work by A = 1/(8 × 5)

⇒ One day work by A = 1/40

And one day work by B = 1/(10 × 6)

⇒ one day work by B = 1/60

One day work by both A and B = one day work by A + one-day work by B

⇒ 1/(A +B) = (1/40) + (1/60)

⇒ 1/(A +B) = (3 + 2)/120

⇒ 1/(A +B) = 5/120

⇒ (A +B) one day work = 1/24 part of one work

Then one work will be done by both A and B in 24 days

Working 8 hrs a day Both A and B can complete a work = 24/8

⇒ Working 8 hrs a day Both A and B can complete a work = 3 days

∴ Working 8 hrs a day Both A and B can complete a work in 3 days.

What are the types of Transmission media?

Answer»

Signals are usually transmitted over some transmission media that are broadly classified in to two categories.

a.) Guided Media: These are those that provide a conduit from one device to another that include twisted-pair, coaxial cable and fiber-optic cable. A signal traveling along any of these media is directed and is contained by the physical limits of the medium. Twisted-pair and coaxial cable use metallic that accept and transport signals in the form of electrical current. Optical fiber is a glass or plastic cable that accepts and transports signals in the form of light.

b.) Unguided Media: This is the wireless media that transport electromagnetic waves without using a physical conductor. Signals are broadcast either through air. This is done through radio communication, satellite communication and cellular telephony.
