D Correct answer
Explanation

Safety precaution while using electricity:

  1. Drain capacitors before working near them and keep the short circuit on the terminals during the work to prevent electrical shock. 
  2. Never touch another person’s equipment or electrical control devices unless instructed to do so. Don’t be too smart. Don’t try your luck. 
  3. Enclose all electric contacts and conductors so that no one can accidentally come into contact with them. If applicable do it always, if not be very careful.

Multiple choice physics when current flows precaution with the electrical circuit precautions to be taken while dealing with current electrical safety devices used to protect from shock of electric current

Which of the following are safety precaution to be taken while using electricity. Select correct answer.

  1. Always use appropriate insulated rubber gloves and goggles while working on any branch circuit or any other electrical circuit.

  2. Never try repairing energized equipment

  3. Never use an aluminium or steel ladder if you are working on any receptacle at height in your home

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The safety precaution to be taken while using electricity:

  1. Always use appropriate insulated rubber gloves and goggles while working on any branch circuit or any other electrical circuit.
  2. Never try repairing energized equipment. Always check that it is de-energized first by using a tester. When an electric tester touches a live or hot wire, the bulb inside the tester lights up showing that an electrical current is flowing through the respective wire. Check all the wires, the outer metallic covering of the service panel and any other hanging wires with an electrical tester before proceeding with your work.
  3. Never use an aluminium or steel ladder if you are working on any receptacle at height in your home. An electrical surge will ground you and the whole electric current will pass through your body. Use a bamboo, wooden or a fiberglass ladder instead.

Multiple choice evs life is precious road safety and pollution personal health care disaster

Wearing helmet is the precautionary measures to avoid electric shock.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Electricity is a produced by the continuous flow of charge. It requires medium to flow from one body to another. The substance through which it can pass are known as conductors and the substance through which it cannot pass are known as insulators. Water is good conductor while wood is a bad conductor of electricity. Wearing helmet is not precautionary measures to avoid electric shock as the helmet is made up of metal which is a good conductor of electricity.

  2. Keeping as far away as is practicable - for example, by using tongskeeping

  3. Keeping radioactive materials in lead-lined containers,

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

D

While handling with radioactive materials we must wear protective clothing and keep it as far as possible. The radioactive materials must be in a lead lined contained because the gamma rays emitting from the radioactive material can be prevented using lead lined materials only.

Multiple choice physics friction advantages and disadvantages of friction merits and demerits of friction and methods to reduce it friction: a necessary evil

In what ways is friction harmful?

  1. It causes wear and tear to the surfaces.

  2. Much energy is lost in overcoming friction.

  3. Both A and B

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Friction comes into play when two irregular surfaces come in contact. The continuous rubbing of these surfaces together causes it to gradually wear out. Also, much of the applied force or energy is wasted in overcoming the force of friction. Hence, it is considered as evil, but it is necessary too.

Multiple choice physics force and newton's laws of motion inertia and mass concept of inertia galileo's law and inertia

Which of the following safety features are used in vehicles to reduce the negative effects of inertia?

(i)Safety seat belts(ii)Automatic air bags(iii)Absorber bumpers

  1. Only (i) and (ii)

  2. Only (ii) and (iii)

  3. Only (i) and (iii)

  4. (i), (ii) and (iii)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

$Force=mass*\dfrac{momentum}{time}$

since the effect of inertia depend on force if the time of impact is increased and hence the same force will produce less effect of inertia the safety seat belt,automatic air bag,Absorber bumpers produce the same effect to decrease the negative effect of inertia.

E Correct answer
Explanation

A sudden accident or a natural catastrophe that causes great damage or loss of life and property is called a disaster. It can be natural like earth quakes, tsunami, floods etc and artificial disasters like terrorist attack etc. Structural measures are any physical construction to reduce or avoid possible impacts of hazards by the application of engineering techniques or technology. For example construction of dams and embankments to control floods, designing electrical power systems to withstand weather and earthquake, enforcing strict building codes to maintain minimum loss in case of collapse during earthquake, seismic resistant designs of buildings, retrofitting public buildings to withstand which is renovation to resist disaster etc.

Early warning system depends upon _____.

  1. Observation and recordings

  2. Risk knowledge and recognition

  3. Warning and dissemination

  4. Appropriate response

  5. All of these
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

A sudden accident or a natural catastrophe that causes great damage or loss of life and property is called a disaster. It can be natural like earth quakes, tsunami, floods etc and artificial disasters like terrorist attack etc. The impact of disaster depends on the precautions we take to save our lives and our environment. One such precaution is early warning system. It provides information regarding disaster before hand and provides ample time to move people from disaster prone areas to safety. Without early warning system the training and evacuation methods can be irrelevant. Early warning system depends on observation and recordings, risk knowledge and recognition, warning and dissemination like spreading news, appropriate response.
