Answer:
KBr
Explanation:
A metal has a very high melting point. Aluminum is a metal.
Ionic solids do not conduct electricity in the solid state. However, when the solids are melted, they conduct electricity.
KBr is an ionic substance, it can only conduct electricity in molten form because the ions are locked up in the solid.
Well the formula for a is a= { vf- vi} ÷ t
where vf is final velocity vi is initial velocity and t is time
thus substituting in the equation you get
a= {13-4} ÷ 1
= 9 m/s2 in the direction of Motion(acceleration is a vector)
The correct option is A.
Chlorofluorocarbon [CFC] is made up of chlorine, fluorine and carbon. In the atmosphere, the CFC moves upward towards the stratosphere, where it will be broken down by ultraviolet radiation to release chlorine, which destroys the ozone layers.<span />
