Answer:
Objects that have like charges attract each other.
Objects that have opposite charges repel each other.
When fur is rubbed on the balloon electrons move from the balloon to the fur.
This is because the balloon's material is an insulator.
Electrons have negative charge.
Protons have a positive charge.
neutrons have no charge.

D. Constructive Interference of waves
Explanation:
Rogue waves occur when wave forms arrive suddenly in oceans, thus causing ships to sink within a very short time. The explanation scientists have for this is constructive interference magnified by second-order bound non-linearities. Waves are meant to arrive in a particular direction. During constructive interference, these waves arrive from different directions and in an organized way thus increasing the height of the wave.
This increased height is as a result of the waves not being in a linear form and having sharp peaks. There is also a significant difference between the crests and troughs. Scientists arrived at this explanation for the rogue waves though three experiments conducted in 1997, 2007, and 2015.
The law of conservation of mass states that the number of atoms of each element on the product side should equal the number of atoms of each element on the reactant side. The unbalanced equation:

Through introspection, we can see that the Oxygen atom (O) has 4 atoms on reactant side and two atoms on product side. So in order to balance the equation we add a coefficient of 2 on the oxygen in the product side, to get a balanced equation:
.
Answer:
First you calculate the distance covered in First 3hrs then calculate the time for the remaining distance then add the total time
“Specific Hazards Arising from the Material: Flammable in the form of dust when exposed to heat, sparks or flame. May react with water under fire conditions to liberate flammable hydrogen gas. May emit fumes of scandium oxide under fire conditions.”
Hopefully this gave you some background information. - j:)
