Highest fluid potential energy: answer A
Because the fluid is pushed upwards and potential energy is function of height. Since point A is the highest, there is the highest potential energy.
highest fluid pressure: answer C
This is because it is at the bottom where you have a hydrostatic pressure component
increasing fluid speed: answer B
This is because the section of the pipe is smaller and in order to have the same fluid flow rate the speed must increase
Answer:
A compass works by detecting and responding to the Earth's natural magnetic fields. The Earth has an iron core that is part liquid and part solid crystal, due to gravitational pressure. It is believed that movement in the liquid outer core is what produces the Earth's magnetic field.
Explanation:
If you are talking about volume, then an easy way to measured the volume of a liquid would be with a graduated cylinder. A graduated cylinder is marked with volume units such as milliliter (mL) or the liter (L). One liter equals 1 thousand milliliters.
To measure the volume of a solid you use the formula V = (Length)(Width)(Height)
To measure the volume of a gas you use a graduated cylinder held upside down. At first the cylinder is filled with water. When air is blown into the cylinder, bubbles rise and push some water down. The volume of the water pushed down is equal to the volume of the gas that was blown in.
Answer:
b -algae
Explanation:
The most common producers in aquatic ecosystems are the algae. They are called phytoplanktons.
- In the food web and food chain of aquatic ecosystems, they usually set out with the algae.
- These algae are called phytoplanktons.
- They are the producers in all aquatic ecosystem.
- Phytoplanktons consists of algae and cyanobacteria.
- Just like plants on land, phytoplanktons manufacture food in an aquatic ecosystem.
Answer:
2. Same force; same impulse; Mini Cooper has greater change in velocity
4. Same momentum
6. It is distributed to the two halves
Explanation:
I will do the even problems as examples.
2. From Newton's third law, we know the bulldozer and Mini Cooper will experience equal but opposite forces. So the magnitude of the force is the same.
Impulse is force times time. Since the force is the same, and the amount of time is the same, then the impulse is the same.
Impulse is equal to change in momentum, or mass times change in velocity. Since the Mini Cooper has the smaller mass, it has the greater change in velocity.
4. Momentum is mass times velocity. The weight of the rover is different on Mars than on Earth, but the mass is still the same. Therefore, if the rover moves at the same speed, it will have the same momentum.
6. The pencil's momentum is conserved. When the pencil breaks in half, half the momentum goes to one half of the pencil, and half the momentum goes to the other half of the pencil.
