A hydraulic arrangement consists of a water- filled U-tube that is wider on one end than on the other. Pistons are fitted in both ends.
I electromagnets, the magnetic field is turned off when there is no induced current. So, electromagnets act as magnets only when current is induced in an insulated wire wrapped around a material mage of ferromagnetic material such as iron core rotating in a magnetic field.
So, option D is the correct one.

Answer:
The answer to your question is 720.5°K
Explanation:
Data
Volume 1 = 285 ml
Temperature 1 = 355 °K
Pressure 1 = 1.88 atm
Volume 2 = 435 ml
Temperature 2 = ?
Pressure 2 = 2.5 atm
Formula
To solve this problem use the combined gas law
P1V1 / T1 = P2V2 / T2
- Solve for T2
T2 = T1P2V2 / P1V1
- Substitution
T2 = (355)(2.5)(435) / (1.88)(285)
- Simplification
T2 = 386062.5 / 535.8
- Result
T2 = 720.53°K
Conclusion
The gas must be heated to 720.5°K
Answer:
The 3rd graph
Explanation:
A free body diagram is a diagram which shows all the forces acting on an object.
The problem asks us to find the free body diagram of block A, so we must find all the forces acting on block A.
We have 3 forces acting on block A in total:
- The force of gravity (its weight), which pushes the block downward (in the diagram, it is the force represented with 
- The tension in the rope 1, which pulls block A upwards: this force is represented with 
- The tension in the rope 2, due to the weight of block 2, which pulls block A downwards: this force is represented with 
Based on the direction of these 3 forces, the correct diagram is the 3rd one.
Answer:
The correct answer is B.
The astronaut will know due to the light from the explosion.
Explanation:
Sound and vibrations require a medium such as air to travel through. Space, there is no air. Only a vacuum. So sound and vibrations are unable to travel. Light requires no medium to travel. It can go through a vacuum.
Therefore the Astronaut will see a bright flash of light as it travels from the explosion to outer space. It is also important to note that light can travel very far because nothing else interacts with its wave particles and as such, it cannot be impeded.
Cheers!
