What is the source of energy for the life in deep sea ocean trenches where sunlight does not reach?
What is the source of energy for the life in deep sea ocean trenches where sunlight does not reach? Answer: Instead of sunlight, vent life relies on hydrogen sulfide – more commonly known as rotten egg gas and toxic to most land-based life. In a process called chemosynthesis, specialized bacteria create energy from the hydrogen […]
What is the intensity of UV light?
What is the intensity of UV light? The intensity of UV radiation is measured in the units of milliwatts per square centimeter (mW/cm2) which is energy per square centimeter received per second. Also, it is measured in the units of millijoules per square centimeter (mJ/cm2), which is energy received per unit area in a given […]
Why is it difficult for a high speed car to negotiate an unbanked turn?
Why is it difficult for a high speed car to negotiate an unbanked turn? (a) A huge force is pushing the car outward. (b) The magnitude of the friction force might not be enough to provide the necessary radial acceleration. A car negotiating an unbanked road at high speed is actually accelerating as the direction […]

Why is NO2 not a greenhouse gas?
Why is NO2 not a greenhouse gas? Neither nitric oxide nor nitrogen dioxide are greenhouse gases, although they are important in the process of creation of tropospheric ozone which is a greenhouse gas. Because of this, there is general agreement that the atmospheric sources and sinks of nitrous oxide are difficult to bring into balance. […]
