Are Roma tomatoes easy to grow? All tomatoes need plenty of water, soil rich in organic material and need to be staked up off the ground for the best fruit production. Roma tomatoes are no different. Romas do tend to be a little easier to grow than other tomatoes due to the fact than many […]

How do you calculate the time it takes an object to fall? The acceleration of gravity near the earth is g = -9.81 m/s^2. To find out something’s speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. […]

What are the four geologic principles? There are several basic principles that geologists use to figure out the history of a rock: Uniformitarianism. Original horizontality. Superposition. Which layer of the rock shows the cross cutting relationship? The youngest layer is at the top. If a geologic feature such as a fault or igneous intrusion cuts […]

What is the 4 second rule? The 4 second rule’s main purpose is to ensure drivers stay at least 4 seconds behind the car in front of them. 4 seconds is proven to be the adequate distance to prevent crashes, contradicting previous estimates of 2-3 seconds. What is the safe stopping rule? The safe rule […]

Which liquid slows faster? Physicists surprised to find that in specially coated tubes, the more viscous a liquid is, the faster it flows. It’s widely known that thick, viscous liquids — like honey — flow more slowly than low-viscosity liquids, like water. What is the thickest liquid in the world? pitch What is something that […]

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 […]

What theory of personality is the best? It is essentially the psychological “blueprint” that informs behavioral patterns. Some of the best-known trait theories include Eysenck’s three-dimension theory and the five-factor theory of personality. What is an example of humanistic perspective? Group therapy for families is an example of a humanistic approach. This type of therapy […]

Which three types of reaction are catalyzed by the pyruvate dehydrogenase complex? 1 The Intermediates Are Covalently Bound Sequentially to Active Sites. Pyruvate dehydrogenase complex is a multifunctional enzyme complex which catalyzes oxidative decarboxylation of pyruvate to acetyl-CoA, NADH, and CO2. What is the advantage to having an enzyme complex as in pyruvate dehydrogenase complex? […]

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 […]

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 […]
