Calculate the molar entropy of Krypton at 298.15K and 1 bar. Assume it behaves as a
monatomic ideal gas with m = 0.08308 kg mol-1 and the degeneracy of the ground
electronic state equal to one.
Hint:
Q(N, V, T)= 1/N![(2πmkBT)/h^2] V^N*gel

A spacecraft arrives at Mars’ sphere of influence with a heliocentric velocity of 22 km/s and a heliocentric fight-path angle of 10 deg. When the spacecraft reaches the periapsis of its Mars-centric arrival trajectory, at an altitude of 200 km, it performs a ∆V to circularize its trajectory. What is the required ∆V ?

Question 1: Given a graph with length l(e) on edges, find a minimum length paths from a vertex s to V −s so that among all shortest lengths paths from s to V −s we find the ones with minimum number of edges.

Use Dijkstra's algorithm

Using C++, write a program to calculate the height and velocity of a ball thrown upward at a user-specified height and speed in 10 seconds. Position (h) and velocity (v) of the ball as a function of time are given by the equations: h(t) =(1/2)gt² + v₀t + h₀ v(t) = gt + v₀

Design an O(nlogn) algorithm that takes two arrays A and B (not necessarily sorted) of size n of real numbers and a value v. The algorithm returns i and j if there exist i and j such that A[i] + B[j] = v and no otherwise. Describe your algorithm in English and give its time analysis.

The merry-go-round rotates counterclockwise with a constant angular speed u. The distance between the horse on the merry-go-round and the rotational center is r.

(a) Find the position of the horse x and its velocity v, v(t) = d/dt x(t), as vector-functions of time.

(b) Find the acceleration of the horse, a(t) = d^2/dt^2 x(t), as a vector-function of time. What is its direction (in comparison with the direction of x)?

Now the same horse has a non-constant angular speed u(t) (the merry-go- round still rotates counterclockwise).

(c) Find the position of the horse x and its velocity v, v(t) = d/dt x(t), as functions of time.

(d) Find the acceleration of the horse, a(t) = d^2/dt^2 x(t), as a function of time.

(e) What is the direction of a(t) at the moment when the merry-go-round starts to rotate?

1. The parking orbit of an Earth satellite has apogee and perigee altitudes of 850 km and 250 km, respectively (this orbit is sometimes referred to as an 850 km x 250 km orbit). (a) Determine the delta v required to circularize the orbit using a single-impulse burn at perigee. What is the period of the resulting circular orbit? Sketch the two orbits, indicating the point where the impulsive burn occurs. (b) Determine the delta v required to circularize the orbit using a single-impulse burn at apogee. What is the period of the resulting circular orbit? Sketch the two orbits, indicating the point where the impulsive burn occurs. (c) Compare parts (a) and (b); which is the least “expensive”. (d) Determine the delta v required to escape from the perigee of the parking orbit. (e) Determine the delta v required to escape from the apogee of the parking orbit. (f) Compare parts (c) and (d); which is the least “expensive.”
