Equations And Definitions Flashcards
(24 cards)
Longitudinal wave
Vibrations that are parallel to the energy transfer
An example of a transverse wave
Light
Respiration equation
Glucose+oxygen=carbon dioxide+water+energy
Photosynthesis equation
Carbon dioxide+water= oxygen+glucose
Equation for weight
Mass x gravitational field strength= weight
Equation for potential difference
Currentxresistance= potential difference
Equation for speed
Distance/time=speed
Reflection
When light travelling through one material bounces of a different one
Refraction
The bending of light; occurs due to a change in speed or direction of a light ray or wave as it travels through one medium to another.
Process of photosynthesis
Photosynthesis is a process by which plants and some bacteria convert light energy into chemical energy producing glucose and oxygen.
Respiration
Respiration is a process by which organisms breakdown glucose to release energy period. There are two types of respiration.There is aerobic respiration which requires oxygen and releases a significant amount of energy and then there is an anaerobic respiration which occurs in the absence of oxygen and releases less energy than aerobic respiration. 
Transparent
Light can pass directly through the object
Translucent
Only some light can pass through the object
Opaque
No light passes through the object and a shadow is formed
carcinogen
A substance that can cause cancer
What human system can be damaged by smoking?
The gas exchange system
What type of cells are damaged in the trachea bronchi and bronchioles by smoke and tar?
Ciliated cells in the trachea bronchi and bronchioles are damaged by smoke and tar
What takes the place of oxygen in red blood cells which is found in cigarette smoke?
Carbon monoxide
What are the risk factors of smoking?
Bronchitis coronary heart disease and emphysema are all risk factors of smoking
What is damaged in patient with emphysema?
The alveoli
What is smokers cough and what is it a result of?
Smokers cough can result from an excess of mucus that helps protect the lungs from infection.
What cancers are linked to smoking?
Lung cancer, mouth cancer and throat cancer
What is a series circuit?
A series circuit is where the circuit elements are arranged in a single path. This means that there is only one route or path the current can take. For example, if there was a string of three lightbulbs and one went out, they would all go out.
What is a parallel circuit?
A parallel circuit is an electrical circuit where components are connected on separate branches. This means that there are two or more paths the current can take.The voltage and potential difference are the same across each branch but the current may vary. For example, if there was a string of three lightbulbs and one went out the other two would still remain on.
