What is the importance of child study? By studying children, we can learn more about why they develop the way they do and also the most effective ways to help them to develop as responsible citizens with positive contributions to make. How can parents/caregivers influence a child’s development? Parents and caregivers offer their children love, […]
How do pressure belts affect climate?
How do pressure belts affect climate? When the air sinks it creates an area of high pressure. Winds blow from areas of high to low pressure, which transfers the air from where it is sinking to where it is rising. This continual transfer of wind maintains the pressure belts of high and low pressure which […]
Can we determine the distance a gun was fired from by the wound?
Can we determine the distance a gun was fired from by the wound? The size and density of the pattern of residues on the object can vary with distance, allowing a firearm examiner to determine the proximity of the shooter to the target when the gun was fired. Examiners test fire the shotgun at different […]
Does pressure decrease with expansion?
Does pressure decrease with expansion? Pressure–Volume Work During an expansion (Figure 12.5), an increase in volume decreases the internal pressure of a system as the system does work. Does pressure change in adiabatic free expansion? Adiabatic free expansion of a gas Because there is no external pressure for the gas to expand against, the work […]
What is the type of mass of spread?
What is the type of mass of spread? e) Spreads: A spread is an extension of a cohesive soil or rock mass combined with a general subsidence of the fractured mass of cohesive material into softer underlying material. The rupture surface is not a surface of intense shear. Spreads may result from liquefaction or flow […]
What is wrong with Anthropocentrism?
What is wrong with Anthropocentrism? Anthropocentrism, in its original connotation in environmental ethics, is the belief that value is human-centred and that all other beings are means to human ends. Environmentally -concerned authors have argued that anthropocentrism is ethically wrong and at the root of ecological crises. What is an example of anthropocentrism? Thus, anthropocentric […]
What are the three main states of matter?
What are the three main states of matter? They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. Can be compressed into smaller spaces? Because there is space between the particles, they can be squashed into a smaller volume when the gas is compressed….particles are fixed to […]
What do polar solvents dissolve?
What do polar solvents dissolve? The rule of thumb is that “like dissolves like”. Polar/ionic solvents dissolve polar/ionic solutes and non-polar solvents dissolve non-polar solutes. For example, water is a polar solvent and it will dissolve salts and other polar molecules, but not non-polar molecules like oil. What are two factors that affect the solubility […]
Which of the following elements is the most reactive Cl Br or I?
Which of the following elements is the most reactive Cl Br or I? 1 Expert Answer Mike – I can tell you the order of reactivity for these specific nonmetals, I<Br<Cl, therefore, Cl is the most reactive nonmetal in this list. Is nitrogen gas heavier than oxygen? Oxygen is denser than both air and nitrogen, […]
Which of these is an example of negative reinforcement?
Which of these is an example of negative reinforcement? Deciding to take an antacid before you indulge in a spicy meal is an example of negative reinforcement. You engage in an action in order to avoid a negative result. One of the best ways to remember negative reinforcement is to think of it as something […]
