Conoces algún proceso o producto de la vida cotidiana en el que se utilice agua oxigenada (H2O2) concentrada?
Answer:
wound disinfectant, to kill fungus, teeth whitener
Explanation:
Hydrogen peroxide or hydrogen peroxide is a polar compound which is why it is a strong oxidant.
Therefore it can be used as a wound disinfectant, to kill fungus, teeth whitener
In industry it is used for toothpastes, fabric bleach and in high concentrations 90% as rocket fuel

Mr. Griffith's car battery died, resulting in his car not being able to start. Mr. Griffith's roommates were all sleeping soundly and he did not have the heart to wake them up, so he decided to walk to school. If Mr. Griffith lives 1.5 miles from the school and can walk at an average speed of 0.5 miles/minute, how long will it take Mr. Griffith to get to school from his house?
Answer:
it will take him 3 minutes.
Explanation:
Students designed an experiment to determine the amount of calories in a chocolate chip cookie. A ring stand was used with a clean aluminum soda can hung from the ring that was partially filled with a known mass of water. A thermometer was placed inside the can so that it measured the temperature of the water but did not touch any part of the metal can. Once set-up was complete, an initial water temperature was taken. The cookie was then lit on fire and allowed to completely burn. A final temperature of the water was measured. Refer to the experimental set-up for calories in a chocolate chip cookie. How does this experiment allow students to measure the calories in a cookie
Answer:
Following are the solution to the given question.
Explanation:
Please find the graph image in the attachment file.
The heat is then transferred to water from the burned cake. The temperature difference is being used to calculate the heat energy of the cookie. Transfer of energy is the move in energy from place to place. Whereas the total quantity of energy may well be moved or converted – it is named energy preservation – does not change.
Will the sun change its location throughout its development
Answer:
Yes
Explanation:
The Earth in orbit around the Sun, with its rotational axis shown. The Earth's axial tilt of approximately 23.5° ensures that observers at different locations will see the Sun reach higher-or-lower positions above the horizon throughout the year.
Two identical cars, each traveling at the same velocity, and having the same mass come to a stop
Car A stops in 0.3 seconds.
Car B stops in 5 seconds.
Which of the following statements is TRUE?
O Car A has less momentum and experiences less force than Car B.
O Car A has the same change in momentum but experiences more force than Car B.
Car A has the same change in momentum but experiences less force than Car B.
© Car A has the same change in momentum and experiences the same force as Car B.
1 2
Answer:
The second option - same change in momentum, different force
Explanation:
They experience the same change in momentum, but the force on car A is greater.
p=m*v
Impulse, or change in p=F*t
We know the cars have the same change in momentum, because they both go from the same initial momentum (p=mv), to zero momentum. Therefore, both experience the same change in momentum. Since the time is different, but the change in momentum is the same, the force has to be different.
For example: if both cars had 200 kg*m/s of momentum at the start, and 0 at rest, the impulse is 200 kg*m/s
So,
p(a)= 200=F(0.3)
p(b)= 200=F(5)
Which force has to be greater to make the equations true? The force for Car A, of course!
A 78-kg skydiver has a speed of 62 m/s , what is the kinetic energy?
Answer:
149,916J
Explanation:
Pneumonic device: Kevin is half-mad and very square
this translates to: KE=(1/2)mv^2 !!
KE=(1/2)(78)(62^2)
KE=(39)(3844)
KE=149,916 Joules
Answer:
it's 149916
Explanation:
Formula = 1/2 x m x v^2
so if you put into your calculator 1/2 x 78 x 62^2
you get 149916
