Can you start a fire using a convex mirror? e) One cannot start a fire using a mirror, since mirrors form only virtual images. Q.An object is located a distance do = 7.2 cm in front of a concave mirror with a radius of curvature r = 18.1 cm. Can you start a fire with […]
Do plants take oxygen out of water?
Do plants take oxygen out of water? Oxygen dissolves into water from two sources: the atmosphere and from plants in the water. In the presence of sunlight, these produce oxygen through photosynthesis and release this oxygen into the pond water. At night and on very cloudy days, algae and submerged plants remove oxygen from the […]
What is the weight of a 1000 kg car?
What causes capacitors to discharge?
What causes capacitors to discharge? If a path in the circuit is created, which allows the charges to find another path to each other, they’ll leave the capacitor, and it will discharge. For example, in the circuit below, a battery can be used to induce an electric potential across the capacitor. How fast do capacitors […]
How much energy does fusion release?
How much energy does fusion release? Each D-T fusion event releases 17.6 MeV (2.8 x 10-12 joule, compared with 200 MeV for a U-235 fission and 3-4 MeV for D-D fusion). On a mass basis, the D-T fusion reaction releases over four times as much energy as uranium fission. What are the cons of nuclear […]

Can you filter out phosphates?
Can you filter out phosphates? Reverse Osmosis is one of the most common and effective methods used for treatment and removal of Phosphates in drinking water. The heart of the system is the Reverse Osmosis (RO) filter that removes contaminants down to 0.0001 microns – so small that only water molecules can squeeze through but […]
How do you interpret a regression summary?
How do you interpret a regression summary? The regression results comprise three tables in addition to the ‘Coefficients’ table, but we limit our interest to the ‘Model summary’ table, which provides information about the regression line’s ability to account for the total variation in the dependent variable. How is P value calculated in linear regression? […]
What is critical period in development?
What is critical period in development? What is the critical period? Also known as the sensitive period, the critical period is a time during early postnatal life when the development and maturation of functional properties of the brain, its ‘plasticity’, is strongly dependent on experience or environmental influences. What are the five main areas of […]
What are the major tissues in the respiratory system?
What are the major tissues in the respiratory system? The conducting passageways of the respiratory system (nasal cavity, trachea, bronchi and bronchioles) are lined by pseudostratified columnar epithelial tissue, which is ciliated and which includes mucus-secreting goblet cells. Do lungs have nervous tissue? The lungs are innervated by the parasympathetic and sympathetic nervous systems, which […]
