How do you calculate the energy content of fuel? where H = heat energy absorbed (in J), ∆t = change in temperature (in °C), m = mass (in g), and Cp = specific heat capacity (4.18 J/g°C for water). Dividing the resulting energy value by grams of food burned gives the energy content (in J/g). […]

What happens to magnetic potential energy when repelling magnets are forced together? The field produces a repulsive force pushing them apart. They repel each other. In this case, the closer they are, the higher their potential energy will be. If allowed to move, they may move as far apart as possible or one will swing […]

When current is circular magnetic field is straight? The magnetic field produced due to a straight current carrying conductor is in the form of concentric circles. The centre of the circles lies on the conductor itself and are in the plane perpendicular to the straight conductor. This implies that the magnetic field produced due to […]

How is a burette better than a measuring cylinder? The burette is better for delivering a precise amount of volume, it’s best for titrations. A graduated cylinder is good for delivering a large amount of liquid (~1mL to 1L) with only a fair degree of accuracy. How precise is a burette? The burette tube carries […]

What is used to measure longer length? Centimeters and millimeters help measure smaller lengths and meters and kilometers help measure larger lengths like distance. For example, the length of the pencils can be calculated in centimeters (cm), while kilometers can measure the distance between two buildings or places. What do you need to know in […]
