Which three of the following are examples of feedback mechanisms which help maintain homeostasis? Answer: The correct answer is- C. Insulin secretion in response to high blood sugar. D. F. Homeostasis can be described as a tendency of living organisms to maintain a state of stable internal environment. Thus, option C), D), and F) are […]
Is angular momentum conserved rolling without slipping?
Is angular momentum conserved rolling without slipping? In rolling motion without slipping, a static friction force is present between the rolling object and the surface. A rigid rotating body has angular momentum directed along the axis of rotation. 11.4: Conservation of Angular Momentum. In the absence of external torques, a system’s total angular momentum is […]
What is U value of insulation?
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 […]

The skull is composed of two parts: the cranium and the mandible…. Skull TA98 A02.1.00.001 TA2 406 Anatomical terminology What […]
What is a disadvantage of hydrogen fuel cells?
What is a disadvantage of hydrogen fuel cells? There are disadvantages to using hydrogen-oxygen fuel cells in cars. These include: hydrogen is in the gas state at room temperature and pressure, so it is difficult to store in the car. fuel cells and electric motors are less durable than petrol engines and diesel engines, so […]

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 […]
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. […]
