  2. Silver

  3. Gold

  4. Platinum
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Circuit boards contain small quantities of various precious and heavy metals. Among them, gold is used for plating connectors and contacts due to its excellent conductivity and corrosion resistance, making it the most valuable recyclable component per unit mass.

Multiple choice evs sources of water conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources

How much radiant energy will an object emit if its temperature is at absolute zero?

  1. The maximum theoretical amount

  2. None

  3. The same as it would at any other temperature

  4. Depends on the chemical composition of the object
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

According to the third law of thermodynamics, at absolute zero, all molecular motion ceases, and therefore an object emits no radiant energy (thermal radiation).

Method of managing used envelope: Reuse: : Method of managing fuels.

  1. Recycling

  2. Use for repurpose

  3. Reduce the use

  4. Refuse the use
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The waste management hierarchy emphasizes the 3Rs: Reduce, Reuse, and Recycle. If reusing an envelope is a management method, reducing the consumption of fuel is the corresponding conservation strategy.

Multiple choice evs sources of water conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources

To meet energy crisis what other sources can be exploited?

  1. Wind

  2. Water

  3. Nuclear

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

The wind, water, and nuclear energy are renewable forms of energy resources. These reserves once consumed can be replenished again. When there is an energy crisis, due to the reduction in the number of energy reserves, there will be an increase in the use of renewable resources. These energy resources can be exploited for the production of energy when there are no other resources available. 

Thus, the correct answer is option D.

Greatest problem in the water conservation is to reduce the amount of

  1. Ground water

  2. Precipitation

  3. Evaporation

  4. Run off water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Evaporation from water reservoirs in hot arid climates causes a loss of 10 vertical feet a year. This water loss can be controlled by construction of reservoirs with greater water depth and concentration of water into single reservoir. Also wind blowing across the surface of water reservoir causes additional evaporation. A windbreak helps to conserve water. Thus the correct answer is option C.

Multiple choice biology garbage in, garbage out recycling of paper ways to reduce non degradable garbage recycling reduce, recycle, reuse

Which one is recyclable waste?

  1. Paper

  2. Torn clothes

  3. Metallic and plastic discards

  4. All the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Recyclable wastes can be reused into new materials. For example, paper can be recycled and this will reduce deforestation because the paper is made from wood pulp. Torn clothes can be recycled to form bags and into other usable forms. Metallic and plastic discards can be melted and recycled into usable forms any number of times. Recycling reduces environmental pollution and uses less energy as compared to the production of new materials from raw materials.
Hence, all the options are correct.
So, the correct answer is 'All the above'.
