How do skiers reduce drag? Skiers can reduce drag by performing an effective ‘tuck’. To do a tuck, lower your stance and level your back parallel to the slope. This position means less wind hits your body, and the eggs-with-legs shape lets wind cut around you, reducing drag even further. Why do longer skis go […]
How do you find boiling point with temperature and pressure?
How do you find boiling point with temperature and pressure? If the boiling point values for a specified substance at a specified BP temperature and pressure are given, one can determine the Boiling Point at different vapor pressure values using the Clausis-Clapeyron Equation. The Clausis-Clapeyron Equation is derived from VP2=VP1e−ΔHvRT at two different temperatures. What […]
What is the effect of molecular weight on melting and boiling points of alkanes?
What is the effect of molecular weight on melting and boiling points of alkanes? Their melting and boiling points of alkanes are relatively low. The higher the molecular weight (the greater the number of carbons), the higher the boiling point. What is the major use of alkanes? Use of Alkanes Alkanes are important raw materials […]
What are the 3 aspects of sound?
What are the 3 aspects of sound? Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. What is the […]
Does odometer measure speed or velocity?
Does odometer measure speed or velocity? The odometer gives us only the measure but doesn’t show the direction of velocity. The odometer measures the scalar quantity – the speed of the car. The device may be electronic or mechanical or a combination of the two. How do you calculate distance traveled using odometer? The formula […]
What is malleability and example?
What is malleability and example? It is the ability of a solid to bend or be hammered into other shapes without breaking. Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead. Gold and silver are highly malleable. The property is not seen in non-metals. What do you mean by ductility class 8? […]
What is a good amount of kJ to burn a day?
What is a good amount of kJ to burn a day? In order to achieve weight loss an individual needs to consume less energy (kilojoules) than the will body burn. For example if an individual needs 8,700 kilojoules per day to maintain weight, reducing daily intake to 6,600 kilojoules (assuming exercise stays the same), should […]
What is temperature on a PV diagram?
What is temperature on a PV diagram? With everything tied together by the ideal gas law, one variable can always be described as dependent on the other two. Temperature is the slave of pressure and volume on a pressure-volume graph (PV graph). What is name of the curve obtained in PV diagram? Only two thermodynamic […]

What is special about pea plants in genetics?
What is special about pea plants in genetics? To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits (Figure below). As a result, one plant’s sex cells combine with another plant’s sex cells. This is called a “cross.” These crosses produce offspring (or “children”), just like when male and […]
