Is a recession coming 2020? Current projections show a 55 percent chance of a recession in the second half of 2020. The biggest risks are trade war uncertainty and (a) global slowdown. (Odds of a recession between now and the November 2020 election are) 25 percent. (Odds of a recession between now and the November […]
How do you prove a rhombus is a quadrilateral?
How do you prove a rhombus is a quadrilateral? To prove a quadrilateral is a rhombus, here are three approaches: 1) Show that the shape is a parallelogram with equal length sides; 2) Show that the shape’s diagonals are each others’ perpendicular bisectors; or 3) Show that the shape’s diagonals bisect both pairs of opposite […]
Which energy has the shortest wavelength?
Which energy has the shortest wavelength? Gamma Rays Which transition has the highest frequency? (ii) Energy and frequency are directly related. Therefore the highest-energy transition is also the one with the highest frequency (n = 3 —> n = 1). What is the transition Imagen of maximum frequency? 5th spectral line of Humphery series. Which […]
How far back can carbon dating date?
How far back can carbon dating date? C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to approximately 50,000 years ago, although special preparation methods occasionally make accurate analysis of older samples possible. […]
What are the two types of graded potentials?
What are the two types of graded potentials? Graded potentials can be of two sorts, either they are depolarizing or hyperpolarizing (Figure 1). Are EPSPs graded potentials? Graded potentials that make the membrane potential less negative or more positive, thus making the postsynaptic cell more likely to have an action potential, are called excitatory postsynaptic […]
Why do we need controls?
Why do we need controls? Controls allow the experimenter to minimize the effects of factors other than the one being tested. It’s how we know an experiment is testing the thing it claims to be testing. This goes beyond science — controls are necessary for any sort of experimental testing, no matter the subject area. […]
How do you know charges of elements?
What are the 4 factors that affect the rate of diffusion?
What are the 4 factors that affect the rate of diffusion? Several factors affect the rate of diffusion of a solute including the mass of the solute, the temperature of the environment, the solvent density, and the distance traveled. What makes a reaction reversible? Reversible Reactions After products are formed, the bonds between these products […]
Why is the strong force so strong?
Why is the strong force so strong? The strong force holds together quarks, the fundamental particles that make up the protons and neutrons of the atomic nucleus, and further holds together protons and neutrons to form atomic nuclei. As such it is responsible for the underlying stability of matter. What is most powerful force in […]
What is Sir effect?
What is Sir effect? SIR effect finds immense use in explaining Stability of carbocation, acidity and basicity of organic compounds: For example(1): Ortho substituted Benzoic acid is more acidic then meta or para substituted benzoic acid irrespective of nature of group (electron donating group or electron withdrawing group) Is ortho effect and Sir effect same? […]
