20 cze 2024 · take two sets of points, using slope equation calculate density (change in volume/change in mass), repeat twice and find average, find element with closest density. Main steps in procedure. 1. record unknown names. 2. collect 5 different sized samples. 3. record mass three times for sample 1. 4. add water to graduated cylinder, record inital ...
30 cze 2024 · The water flows from a constant head apparatus through a horizontal capillary tube and is then collected by a beaker; the time for a given volume to be collected is measured. The pressure difference between the two ends of the capillary tube is hrg where r is the density of the liquid. The internal diameter of the capillary tube is measured ...
27 cze 2024 · a = (v1 – v)/t. Where a is acceleration, v1 is the object's initial velocity, v is the object's final velocity and t is time. Using this formula to calculate displacement, you would have: d = 1/2 (at2)+vt. Where d is displacement, a is acceleration, t is the time it took to get from the start point to the end point, and v is the final velocity.
2 dni temu · Understanding and being able to accurately calculate the flow rate of a siphon system can greatly improve the efficiency and effectiveness of these systems. ... Siphons require a continuous liquid column and work best when the discharge end is lower than the liquid surface on the supply side. The effectiveness can be limited by factors like air ...
4 dni temu · A carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometre range ().They are one of the allotropes of carbon.Two broad classes of carbon nanotubes are recognized: Single-walled carbon nanotubes (SWCNTs) have diameters around 0.5–2.0 nanometres, about 100,000 times smaller than the width of a human hair.They can be idealised as cutouts from a two-dimensional graphene ...
3 dni temu · Young's modulus (or Young modulus) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise. It is the modulus of elasticity for tension or axial compression. Young's modulus is defined as the ratio of the stress (force per unit area) applied to the object and the ...
5 dni temu · Determine the density and possible identity of the substance, using Table 2. Calculate the volume of water, in millilitres, that would be displaced by 1.82 g of cobalt. 0.204 mL. Briefly explain why the density of a substance, as calculated using the Procedure described in this experiment, would be correct, too high, or too low, if: a) some of ...
