1When some materials are rubbed together, [blank_start]electrons[blank_end] can be [blank_start]transferred[blank_end] from one material to the other.
- Aelectrons
- Btransferred
2A build up of electrons creates a [blank_start]negative[blank_end] charge.
- Anegative
3A lack of [blank_start]electrons[blank_end] creates a positive charge.
- Aelectrons
4Objects that have the [blank_start]same[blank_end] charge will [blank_start]repel[blank_end].
- Arepel
- Bsame
5Insulated materials can be [blank_start]charged[blank_end] by the transfer of electrons.
- Acharged
6If an object is connected to the ground by a conducting material, the [blank_start]charge[blank_end] flows away.
- Acharge
7A charge can pass through a [blank_start]conductor[blank_end].
- Aconductor
8Charge cannot pass through an [blank_start]insulator[blank_end].
- Ainsulator
9If enough charge builds up, a [blank_start]spark[blank_end] may jump across the gap between the body and the earth or an earthed conductor.
- Aspark
10One way to prevent static shocks include to use [blank_start]insulating[blank_end] mats.
- Ainsulating
11One way to prevent static shocks is to wear [blank_start]rubber[blank_end]-soled shoes.
- Arubber
12One way to prevent static shock is to use [blank_start]anti-static[blank_end] sprays.
- Aanti-static
13Photocopiers and laser printers use static to direct [blank_start]ink[blank_end].
- Aink
14[blank_start]Dust[blank_end] can be removed from chimneys by being attracted to a charged plate. Large particles form, falling when they are heavy enough or are shaken.
- ADust
15[blank_start]Finger[blank_end]printing uses static electricity.
- AFinger
16Some dusters are designed to [blank_start]attract[blank_end] dust by static electricity.
- Aattract
17[blank_start]Doctors[blank_end] use static electricity to restart the heart.
- ADoctors
18In paint spraying, paint is charged so that the droplets [blank_start]repel[blank_end] each other, giving a fine, even spay. A surface is given an opposite chage to the paint, ensuring an even coat and less waste.
