Hi, please answer all these questions for me. Most importantly number 4, please don't skip steps on that one. Question 1: (23%)The primitive translation vector of the face centre cubic (FCC) crystal structure may be takenas:112)āî = ¾a(8 + 9); ā¿ =· + 9); āį = = a(9 + 2); ā3 = = a (x + ²Calculate:1. The volume of the primitive unit cell.2. The reciprocal translation vectors: ai, a2, a3, of the primitive lattice.3. The volume of the reciprocal unit cell.4. Determine the crystal structure of the reciprocal lattice.[3][9][5][6]

PLEASE help me with the two questions. These are the only two I need help with and this is my last question until November. Please solve number #7 from the information in 6, and please solve question #9 from the information in number 8. THANK YOU PLEASE HELP!!
I've attached a screenshot of the question i'm trying to solve and I have pictures of my work here https://imgur.com/a/bQ5IaC1 . My work for this problem is under the 2.44 title, any variable with an "s" in the subscript applies to the speeder, and any variable with a "c" in the subscript applies to the police car.
On the map, let the +x-axis point east and the +y-axis north. An airplane flies at 880 km/h northwestward direction (i.e., midway between north and west). Can you help me visualize the components of the first velocity, and when the plane flies due south at the same velocity? I am afraid I can properly visualize or understand in simple terms what is asked. My point can you help to understand the right angle theorem to the angle.
I've been trying to figure out the last three steps for an hour now, but I can't seem to figure out the correct answers.
I'm getting mixed answers for this question. Can I please get someone who is confident in their answer for a) b) and c) ASAP?
Suppose you have collected the set of data below by measuring the amount of time it takes for a small steel ball to fall from a height of 1.5 m to the ground. What value would you report if I asked you for the fall-time of this small steel ball from a height of 1.5 m?
QUESTION 2 At a location where gravity acceleration constant g=9.80 m/s2, a projectile returns to its original height after 5.9 seconds, during which time it travels 74.1 meters horizontally. If air resistance can be neglected, what was the projectile's initial speed: vo = (Note: For fill in blank, I have set the unit for the answer. So, you just need to provide a number - Please write your numerical answer with all digits and do not use scientific notation. If you are not sure about the number of significant figures, you can keep the number of figures as many as possible - You will not be punished for doing this. ) m/s ? QUESTION 3 An airplane needs to reach a forward velocity of 203.0 km/h (Please pay attention to the unit km/h here - km = 1000 m, h = hour) to take off. On a 2000-m runway, what is the minimur uniform acceleration necessary for the plane to take flight if it starts from rest?

Hello, Can I please have help regarding this problem ? Thanks. Suppose that the clock on our lecture room has a minute-hand length of 10 cm.(Use a coordinate system with the origin at center of clock and +x axis along the3PM direction and the +y direction along the 12PM direction). From the 12 to 8mark, for the tip of the minute hand:a) Sketch a vector diagram labeling ri, rf, Δr, Vi, Vf, and ΔV.b) Calculate the displacement vector in unit-vector notation.c) Calculate the average velocity vector in unit-vector notation.d) Calculate the average acceleration vector in unit-vector notation.e) Calculate magnitude and direction of the average acceleration vector.f) Calculate the magnitude and direction of the total acceleration of the tip ofthe minute hand at the 6 mark.
