Physical Sciences Break 1.0

Knowing either the empirical or molecular formula of a compound, can help to determine its composition in more detail. The opposite is also true. Knowing the composition of a substance can help you to determine its formula. There are four different types of composition problems that you might come across: Problems where you will be given the formula of…

https://maimelatct.wordpress.com/ Chipa Thomas Maimela‘s insight: Redox reactions involve the exchange of electrons. One ion loses electrons and becomes more positive, while the other ion gains electrons and becomes more negative. To decide if a redox reaction has occurred we look at the charge of the atoms, ions or molecules involved. If one of them has…

https://maimelatct.wordpress.com/ Chipa Thomas Maimela‘s insight: When we add resistors in series to a circuit: There is only one path for current to flow which ensures that the current is the same at every point in the circuit. The voltage is divided across the resistors. The voltage across the battery in the circuit is equal to the sum of…

https://maimelatct.wordpress.com/ Chipa Thomas Maimela‘s insight: When we add resistors in parallel to a circuit: There are more paths for current to flow which ensures that the current splits across the different paths. The voltage is the same across the resistors. The voltage across the battery in the circuit is equal to the voltage across each of the parallel…

See on Scoop.it – PHYSICAL SCIENCES BREAK 1.0 the angle between the horizontal and the incline is also the angle between the gravitational force and its component perpendicular to the inclined plane (this is normal to the plane). Using this angle and the fact that the components form part of a right-angled triangle we can…
