Give a step by step description of the physics and mathematics needed to calculate the trajectory of a water bottle rocket. In addition, if the location of the landing of a water bottle rocket could be controlled, what is the physics and mathematics needed to establish control?

A single crystal of a metal that has the FCC crystal structure is oriented such that a tensile stress is applied parallel to the [110] direction. The critical resolved shear stress for this material is 1.75 MPa.

1) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (1-10) direction.

2) Calculate the magnitude of applied stress necessary to cause slip to occur on the (111) plane in the (10-1)direction.

3) Which of these two slip systems is the most favourably oriented (which system will see first plastic deformation)?

a) What is insoluble residue (IR) of cement? b) What is its cause? c) The IR of portland fly ash composite cement is considerably higher than of ordinary portland cement produced from the same clinker. Why?

How would your typical day be changed without availability of your principal mode of transportation? Consider both personal transportation as well as goods and services that you rely on.

I just need you opinion guys, essay will do. THANKS!

What is this asking ???

A surveyor compares the bearings at two ends of a line underground by using a gyrotheodolite. The results at each end can be compared after they are corrected for grid convergence, meridian convergence, deflection of the vertical and index error in the instrument. Could the effects of deflection of the vertical be ignored in practice? (Look up some values of the deflection of the vertical in extreme cases, and estimate how much they affect directions).

Case Study: Carded Graphics, LLC: Sheeter Replacement Decision.

1. Desribe the value drivers of the sheeter replacement decision?

1- Give information about the stages of concrete production. Discuss any two stages in detail.

y'(1+x^2)=(1/1-x)-3xy find the general solution.

Discuss briefly activated sludge age in terms of treated effluent quality.

Write a report showing the processes of the St Mary's wastewater treatment plant.

The report should include:

- General information about the plant (place, purpose, treatment capacity)

- Simplified flow diagram of the plant (showing only the important treatment processes)

- Functions of the each process (a few lines for each)

- Operational and maintenance issues of 2 processes in the plant

- References

Explain the different events that led to the entry of the United States into both the First World War (1914-1918) and the Second World War (1939-1945). Also pay attention to what specific role the US played in bringing these two wars to an end.

The City of Pomona (CA) has a population of 152,361. According to the data from 2017 to 2019, the average day demand in Pomona is 611 liters per capita per day (LCD). A new residential complex is being constructed in Pomona. There will be 16 three-story non-combustible apartment buildings, with an estimated total number of residents of 300 living in this apartment complex. Each building will have the same floor areas as follows: first floor, 1600 ft2 (square feet); second floor, 1400 ft2; third floor, 1200 ft2. The proximity and exposure between buildings can be considered average (use default). Using default peaking factors, please estimate the water demand for this new residential complex.
