Air pressure is the amount of molecules in the air. For example, the higher you go in Earth's atmosphere the less pressure so less molecules. <span />
Answer:
671.76 kg or 6590 N
Explanation:
So the buoyant force generated by the floating ice is equals to the mass of water displaced by the submerged ice. We also need to account for gravity of ice. The resulting additional mass that the ice sheet can support is the difference between the mass of water displaced by ice and the mass of ice submerged totally in water.
So the ice piece can support an additional 671.76 kg of bear, or 671.76 * 9.81 = 6590 N
Answer:
glucose → NADH → electron transport chain → oxygen.
Explanation:
Aerobic respiration is also called as cellular respiration, in which electrons are picked up by the FADH, and NADH from the food. Then through a proton pump electrons are transferred to the electron transport chain, in this, the activity of the proton pump generates an electrochemical gradient, then this gradient used by the ATP synthase enzyme to produce ATP.
In aerobic respiration, the last acceptor of electron is oxygen. An electron is donated to oxygen for the formation of the water.
3 is B my dude and the reason nobody answered is because thousands of questions are asked every day. So not every question can be answered. It doesn't have to do with being lazy.
Answer:
It has been converted into thermal energy due to friction
Explanation:
According to the law of conservation of energy, energy cannot be created nor destroyed, but only transformed from one form into another.
Applied to this problem, it means that the total initial energy of the spring-toy system must be conserved.
Therefore:
- At the beginning, the total energy stored in the spring is 10 J
- After the toy is released, the total energy must still be 10 J.
In reality, we are told that the kinetic energy of the car is only 8 J. The other 2 J have not been destroyed, but they have been converted into thermal energy, due to the presence of frictional forces that act against the motion of the toy car.
