Q: An electric stove changes electric current to what form of energy? Read this paragraph and choose the correct option from the provided answers: Electric devices, such as lights and household appliances, change electric current to other forms of energy. For example, an electric stove changes electric current to thermal energy. Other common devices, such as mobile phones and computers, use electric current for another purpose: to encode information. A message encoded this way is called an electronic signal , and the use of electric current for this purpose is called electronics . For an overview of electronics and electronic signals, read the short article at this URL: http://www. bbc. co. uk/scotland/learning/bitesize/standard/physics/electronics/overview_rev1. shtml . Choices: - thermodynamic - kinetic - nuclear - thermal A:
**Answer**

Q: When does internal reflection occur? Read this paragraph and choose the correct option from the provided answers: Total internal reflection occurs when light goes from a slow (high index of refraction) medium to a fast (low index of refraction) medium. With total internal reflection, light refracts so much it actually refracts back into the first medium. This is how fiber optic cables work: no light leaves the wire. Choices: - when light goes from a slow medium to another slow medium - when light goes from a fast medium to a slow - when light goes from a fast medium to another fast medium - when light goes from a slow medium to a fast A:
**Answer**
when light goes from a slow medium to a fast

Q: An endocrine disease usually involves the secretion of too much or not enough hormone by which gland? Read this paragraph and choose the correct option from the provided answers: Diseases of the endocrine system are fairly common. An endocrine disease usually involves the secretion of too much or not enough hormone by an endocrine gland. This may happen because the gland develops an abnormal lump of cells called a tumor. For example, a tumor of the pituitary gland can cause secretion of too much growth hormone. If this occurs in a child, it may result in very rapid growth and unusual tallness by adulthood. This is called gigantism. Choices: - Pituitary - Thyroid - Pancreas - endocrine A:
**Answer**
endocrine
