Answer: The surface of the pad pushes the rocket up while gravity tries to pull it down. As the engines are ignited, the thrust from the rocket unbalances the forces, and the rocket travels upward. Later, when the rocket runs out of fuel, it slows down, stops at the highest point of its flight, then falls back to Earth.
Answer: The chemical formula for the compound of these two elements is 
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here metal lead is having an oxidation state of +4 called as 
cation and sulphur non metal has oxidation state of -2 called as 
. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
The chemical formula for the compound of these two elements is
Answer:
The 2nd option
Explanation:
It slows down the transfer of thermal energy from inside to outside the coat.
The answer to the question you have asked is 1.8 miles east.
Answer:1.28v/k
Explanation:
Thermoelectric power is the same as Seebeck coefficient.
So the formula is S =Vemf/Th - Tl
= 12.8/310-300
S= 12.8/10
=1.28V/T
