What is the major advantage of the field experiment? Field Experiment Strength: behavior in a field experiment is more likely to reflect real life because of its natural setting, i.e. higher ecological validity than a lab experiment. Strength: There is less likelihood of demand characteristics affecting the results, as participants may not know they are […]

Who discovered the nuclear? December 1938: Discovery of Nuclear Fission. In December 1938, over Christmas vacation, physicists Lise Meitner and Otto Frisch made a startling discovery that would immediately revolutionize nuclear physics and lead to the atomic bomb. What is a nuclear scientist called? A nuclear scientist is a physicist who studies how to harvest […]

How many types of fingerprint patterns are there? eight different types How deep are your fingerprints? High quality prints appear to correlate with an optimal penetration depth-between 40 and 60 microns. What is the dogmatic principle of fingerprint? Fingerprint is governed by three dogmatic principles which are recognized judicially by the different courts of the […]

How can I use platform balance? The Tech Facility beam balance is a two platform balance, and can be used in two ways: (a) You can place objects or weights on both platforms and balance them against each other, or (b) you can weigh something on just one platform. Before using the balance for weighing, […]

Is iPhone 11 Pro Max too big? The iPhone 11 Pro Max was, of the three devices, the largest, heaviest and most expensive. She also noted that the phone is “just too big,” and one of many iPhones that are “too big for the average woman’s hands.” It’s also the heaviest iPhone ever. Some on […]

Does boiling water go above 212 degrees? Above 212°F at standard pressure, liquid water is unstable. in it, this boiling process doesn’t happen until the temperature is significantly above 212°F, so you can temporarily have liquid water (called ‘superheated’) above that boiling point. Is steaming faster than boiling? Steaming makes your vegetables taste better. Steaming […]

What is the formula for tangent? The tangent function, along with sine and cosine, is one of the three most common trigonometric functions. In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). In a formula, it is written […]

Does water or oil cool faster? The rate of heat flow will be determined by the thermal conductance of the pot and the temperature difference between the liquid and the surrounding. Since the water has a higher specific heat than most oils, it would have to lose more heat to cool down, and you would […]

Why does surface area affect the rate of weathering? If a large rock is broken into smaller pieces, weathering happens much more quickly. The rate of weathering increases because the surface area-to-volume ratio of the small rocks is greater than that of the large rock. So, a greater proportion of a smaller rock is exposed […]

How can you make an object more stable? There are two ways of making an object more stable. One way is to lower its centre of gravity. Racing cars have very low centres of gravity, so that they are less likely to roll over enven when cornering at high speeds. The other way is to […]
