Answer:
The nail exerts a force of 573.88 Pounds on the Hammer in positive j direction.
Explanation:
Since we know that the force is the rate at which the momentum of an object changes.
Mathematically ![\overrightarrow{F}=\frac{\Delta \overrightarrow{p}}{\Delta t}](https://tex.z-dn.net/?f=%5Coverrightarrow%7BF%7D%3D%5Cfrac%7B%5CDelta%20%5Coverrightarrow%7Bp%7D%7D%7B%5CDelta%20t%7D)
The momentum of any body is defines as ![\overrightarrow{p}=mass\times \overrightarrow{v}](https://tex.z-dn.net/?f=%5Coverrightarrow%7Bp%7D%3Dmass%5Ctimes%20%5Coverrightarrow%7Bv%7D)
In the above problem we see that the moumentum of the hammer is reduced to zero in 0.023 seconds thus the force on the hammer is calculated using the above relations as
![\overrightarrow{F}=\frac{m(\overrightarrow{v_{f}}-\overrightarrow{v_{i}})}{\Delta t}](https://tex.z-dn.net/?f=%5Coverrightarrow%7BF%7D%3D%5Cfrac%7Bm%28%5Coverrightarrow%7Bv_%7Bf%7D%7D-%5Coverrightarrow%7Bv_%7Bi%7D%7D%29%7D%7B%5CDelta%20t%7D)
![\overrightarrow{F}=\frac{m(0-(-73.33)}{0.23}=\frac{1.8\times 73.33}{0.23}=573.88Pounds](https://tex.z-dn.net/?f=%5Coverrightarrow%7BF%7D%3D%5Cfrac%7Bm%280-%28-73.33%29%7D%7B0.23%7D%3D%5Cfrac%7B1.8%5Ctimes%2073.33%7D%7B0.23%7D%3D573.88Pounds)
Answer:
Check the explanation
Explanation:
The Total pressure is the overall of fixed or static pressure p, the dynamic pressure q, as well as gravitational head. Total pressure can also be referred to as the measure of the overall energy of the airstream, and is the same to static pressure plus velocity pressure.

Answer:
b. the supremacy clause
Explanation:
This is clearly a violation of the supremacy clause of the constitution. The supremacy clause makes the constitution and federal laws made under the constitutional authority the supreme law of the united state. And in a case where there is a conflicting state law, as we have here with Oregon, the federal law is supposed to take priority.
So in this case where the federal law and the state law do not agree, the feral law has the power to override the law of the state. So oregon has violated the supremacy clause
Answer:
Both Technician A and B are correct
Explanation:
Due to a contamination of the clutch disc friction surface, the clutch chatters
The contamination that causes clutch chattering includes
1) Worn or broken motor mounts
2) Bell housing bolts becoming loose
3) Clutch link damage
4) Warped flywheel, due to overheating, the flywheel can become warped such that the non uniform surface interfaces the clutch resulting in clutch chattering
5) Engine or transmission oil contaminating the disc.
