Answer:
Potential Energy
Explanation:
The electron transport chain is a series of proteins and organic molecules located in the inner membrane of the mitochondria.During electron transfer and proton pumping electrons are moved from a higher energy level to a lower one and in the process release energy.This energy is used to make ATP.It is stored in the electrochemical gradient of protons and it has to be released for electron transport to continue.
Answer:
Test (OR you may decide to call it study)
Answer:
3160.41J
Explanation:
From the work energy theorem, the net work done is given by;
W = Kef - Keo
Where kef is final kinetic energy and keo is initial kinetic energy.
Now, from the question,
m = 62.8 kg
Initial speed(vo) = 5.2 m/s
Final speed (vf) = 11.3 m/s
We know that formula for kinetic energy is K = (1/2)mv²
Thus, Kef = (1/2)mvf² and Keo = (1/2)mvo²
Thus;
W = (1/2)mvf² - (1/2)mvo²
W = (m/2)(vf² - vo²)
W = (62.8/2)(11.3²-5.2²)
= 31.4(100.65) = 3160.41J
Yes they do because they just have to
The safety contract will include basic lab safety guidelines such as:
- Remove all flammable materials from the work station.
- Avoid leaving the heating set-up unattended.
- Fold long sleeves, tie back long hair, remove all accessories that may catch on fire.
- Wear proper lab attire.
- Avoid horse-playing in the lab.
- Report any injuries to the teacher, no matter how minor, as soon as possible.
- Avoid working alone inside the lab.
- Make sure you are aware of the location of the safety equipment and features of the lab especially the first aid kit, fire exit, fire blanket, and fire extinguisher.
- Follow instructions carefully.
- Dispose materials properly.
- Report any faulty equipment as soon as possible.
- Avoid touching hot surfaces with bare hands.
- Wash all used glassware.
- Keep workstation clean and tidy to avoid accidents.
- Avoid eating and drinking inside the lab.
- Put away unnecessary things. Only materials needed for the investigation must be on the workstation.
Further Explanation:
In his safety contract, Chris will find statements that has him agreeing that he will behave appropriately inside the lab especially since they will be working with an open fire (Bunsen burner) or a heating equipment (hot plate) to change the temperature of the water. Proper behavior and basic expectation inside a lab are in the items listed above.
