No, you wouldn't do any more work by going up the stairs twice as fast.
work done is equal to : F x D
time is not included, which mean you only done the work faster, but not doing any more work compared to the slower one
hope this helps
Answer:
Zero
Explanation:
It is given that,
A person swims to the other end of a 20m long pool and back.
We need to find his displacement.
Displacement = shortest path covered
He reaches at the same position as from where he has started. It means the shortest path covered is equal to 0 i.e. his displacement is zero.
Answer: False
Explanation:
The statement that the environment affects people, but people don't affect the environment is incorrect. It should be noted that people also affect the environment.
Some of our impact on the environment include pollution, deforestation, overpopulation, burning of fossil fuels etc. Thus has resulted in changes such as erosion, climate change, etc.
Answer:2H2O2 → 2H2O + O2
Explanation:
For a chemical equation to be balanced, the number of moles of each element at the reactant must be equal to that of the product.
According to the equation given
H2O2 → H2O + O2
There are two hydrogen atoms with two oxygen atoms at the reactant and 2hydrogen and 3oxygen at the product which shows the equation is not balanced. To balance this,
We will add 2 moles to H2O2 at the reactant and 2 moles to H2O at the product to give;
2H2O2 → 2H2O + O2 (Balanced equation)
As we can see that we now have 4 moles of Hydrogen and 4 moles of oxygen at both reactant and product making the equation balanced.
