Answer
Hi,
In a chemical equation, chemicals that react are the reactants, while chemicals that are produced are the products/by products. Both sides of the equation must be balanced.
Explanation
When writing a chemical equation, reactants reacts to produce products. For example in the equation for formation of water, hydrogen combines with oxygen as 2H₂ +O₂→2H₂O where the first part before the arrow represent the reactants and the next part after the arrow are the products. Reactants are on the left where as products are on the right.Coefficient 2, in this cases is used for balancing the equation.
Good luck!
Answer:
the highest point the rocket reaches is
Explanation:
Hi
First of all we are going to use while the engine is on, so .
Second, we're going to find the speed as the engine shuts off, so we have
Third, we need the time when the rocket reaches max high after engine turns off, to do that we use , then we isolate t,
Finally we can find highest point by using
Answer:
Explanation:
We are given that
Final velocity, v=199 km/h=
1km/h=
Initial velocity, u=0
S=2000 m
We know that
Using the formula
Hence, the minimum acceleration necessary for the plane to take flight=
I guess 48 , but I’m not sure
