When a distribution is positively skewed it is very different from a typical bell curve result, a normal distribution, as it has a long right-hand tail. High scores are occurring at the extreme, so the distribution will have the mean score to the right of the peak.
The mean is usually greater than the median, which is always greater than the mode (most displayed score). If a group's ...
The merry go round has a spinning motion and is a good example of centrifugal force. When you sit on the edge you feel dizzier than if you sit in the middle. This is because your inner ear helps you keep your balance, and when it's disturbed by a spinning force you feel dizzy.
There's a greater force on the edge, and therefore you get dizzier. This feeling of being pushed outward is ...
There is only one syllable in the word 'thought' but there are three phonemes, th, ough, and t. children are now taught phonemes at school but many, understandably, find it very difficult on meeting a new word to 'sound out' phonemes that then do not make a word sound they can recognise.
This is because of the irregularity of our language, unlike, say, Spanish, where sounding out ...
I think this question is seeking a differentiation between physical and chemical changes. An example of physical change is when hot water is poured over an ice cube. The ice rapidly turns back into liquid. Physical changes make matter take a different form: size, shape, color.
Also, physical changes occur when substances are mixed but don't chemically react. No new substance is ...
It would be difficult to overthrown Assad with the kind of support the receives from Russia (provision of air support and diplomatic cover), Iran and support from several shiite militia this is almost an impossible feat to overthrown Assad in the nearest future.

The other long bone in the forearm is the radius and ulna runs parallel to it. The two bones give structure to the forearm. It joins with ...
The correct answer is option A (- 3).
Elements in the periodic table are arranged according to the number of ions they have, for example, sodium a group 1 element has +1 cation, group 2 elements like calcium has +2 cation. Potassium is a group 1 element which means it has one cation. However, some elements from numerous different ions.
Example of such is phosphorus, it can exist ...
Option C - mass
Mass doesn't change in physical or chemical change.
Physical change are changes that affect the form of a substance. Example is the change in the state of water from solid to liquid and to ice.
Chemical change is a type of change that occurs when a substance is changed from one form to another form that cannot be reversed. Chemical composition ...
Option A is correct.

Option E is correct.
In the above question, hydrogen peroxide is behaving as a reducing agent. Hydrogen peroxide is reducing silver from an oxidized state to a reduced state. Oxygen is been removed from silver.
In the reaction, oxygen is formed in it's pure state and hydrogen peroxide is been oxidized to form water. This chemical reaction represents an example of a Redox ...
