Answer 1

The given statement "When solving the impact problems, we should always assume that during an impact between two bodies, there is no permanent deformation in the bodies" is False and  there is usually some amount of permanent deformation during an impact when semi-truck collides head-on with a mini car.

The statement is False because In reality, there is usually some amount of permanent deformation that occurs during an impact, especially if the impact is severe. However, in many cases, the amount of deformation may be negligible or can be ignored for simplicity in calculations.Therefore the statement is False.

If a semi-truck collides head-on with a mini car then According to Newton's Third Law of Motion, every action has an equal and opposite reaction. Therefore, both the semi-truck and the mini car will exert equal force on each other during a head-on collision. The force experienced by each vehicle will depend on factors such as their mass, speed, and the duration of the impact. However, it is likely that the semi-truck, being much larger and heavier than the mini car, will experience less of a change in velocity than the mini car and therefore will exert more force on the smaller vehicle.

how does the sovent drainage and waste system operate without the venting piping used in traditional systems?

Answers

The solvent drainage and waste system operates without venting piping by using a combination of air flow and pressure.

Instead of relying on venting piping to exhaust fumes and waste, the system takes in air from the atmosphere and circulates it through the system with a blower or compressor. This creates a pressure difference that drives the solvent out of the system, taking any remaining waste with it. The pressure also keeps odors from escaping and prevents the system from backflowing.

Drainage is the removal of a mass of water either naturally or artificially from the surface or subsurface from a place.
