As your spaceship coasts toward Mars, you need to move a heavy load of 1200 kg along a hallway of the spacecraft that has a 90 degree right turn, without touching the walls, floor, or ceiling, by working remotely, using devices attached to the load that can be programmmed to fire blasts of compressed air for up to 1.0 s in any desired direction. During a blast the load is subjected to a force of 20 N. The center of the load must move 2 m along the first section of the hallway, starting at rest. Let the starting point be <0,0,0> m, with the first section ending at <4,3,0> m. Using just three blasts of compressed air, choose the times when these blasts should be scheduled, their durations, and their directions. How long does it take to complete the entire move?

I know it is not 24 s a similiar or the same question was post at another time and it is wrong. I came up with 13 minutes roughly. If you could be do your best to answer this question, the question is from matter & interactions 4th edition modern mechanics chapter 2. This question was within the usage of the momentum principle section and although you need a grasp of this principle a d = \v\ * t can be used to calculate it I believe. I used a small window of acceleration of 0.5s and a total of 1.0s acceleration at the turn two positions .5s each one ending another starting to get the one blast necessary then .5 seconds of deacceleration at the 4m interval end.  

Hope someone really answer this thank you.

By studying seismic measurements and geological evidence, scientists have made the following obser
vations about earthquakes. i. Small tremors (magnitude below 1.0 on the Richter scale) are almost constantly oc
curing on every continent.
ii. The number of earthquakes with magnitude at least 3.0 on the Richter scale averages
200,000 per year, worldwide.
iii. Based on geological evidence, the number of major earthquakes (magnitude> 7.0 on
the Richter scale) has averaged 20 per year, and this average rate has not changed over
the last 10,000 years.
iv. The number of earthquakes occurring each year is independent of the number that
occurred in any previous year.
v. The magnitude of an earthquake is inversely proportional to the logarithm of the
frequency that earthquakes of at least that magnitude occur. In other words, let
X(m) denote the expected number of earthquakes per year with magnitude greater
than or equal to m. Then logX(m) is proportional to m.
(a) Explain why it is reasonable to use a Poisson random variable to model the number of major
earthquakes occurring in any given period of time? Indicate which of the above observations
support your explaination.
(b) Let N(t) be a Poisson random variable that models the number of major earthquakes (magnitude
> 7.0) that will occur in the next t years. Give the probability mass function for N(t).
(c) Calculate the expected value and standard deviation for N(3).
(d) Calculate the probability that there will be at least 3 earthquakes in the next month.

You plan to invest in the Kish Hedge Fund, which has total capital of $500 million invested in five stocks:

Kish's beta coefficient can be found as a weighted average of its stocks' betas. The risk-free rate is 5%, and you believe the following probability distribution for future market returns is realistic:

1. What is the equation for the Security Market Line (SML)? (Hint: First determine the expected market return.)
   1. r_i = 3.7% + (7.3%)b_i
   2. r_i = 5.0% + (6.9%)b_i
   3. r_i = 4.0% + (8.1%)b_i
   4. r_i = 4.0% + (6.9%)b_i
   5. r_i = 5.0% + (8.1%)b_i

5. Today Van de Graaff accelerators sometimes serve as “injectors” for other types of accelerators that then further increase the energy of the particles. Consider a Van de Graaff accelerator that is being used to accelerate protons. The high voltage terminal (metal sphere) of the Van de Graff is charged using a rubberized belt that is 30 cm wide and travels at a velocity of 20 m/s. Charge is sprayed onto the belt near the roller at the low voltage end and removed from the belt near the upper roller inside the high voltage terminal. The belt is given sufficient surface charge density at the lower roller to cause an electric field of 1.0 MV/m (i.e. approaching the breakdown field of air at atmospheric pressure which is ~ 3 MV/m) on each side of the belt. (a) What is the charging current delivered to the high voltage terminal in µA? Suppose we would like to accelerate the protons to an energy of 3 MeV. Take the radius of the spherical high voltage terminal to be the such that the electric field at the surface of the sphere just below the breakdown field of air (b) How long does it take to charge the high voltage terminal of the Van de Graaff from zero volts to 3 MV? The beam of 3 MeV protons is focused onto a lithium target. The beam is equivalent to a current of 5 µA. (c) At what rate do protons strike the target? (d) At what rate is energy (heat) produced in the target? (e) Would you consider the Van de Graaff a ‘source of emf ? Why or why not?

Iconic memory is a type of memory that holds visual information for about half a second (0.5 seconds). To demonstrate this type of memory, participants were shown three rows of four letters for 50 milliseconds. They were then asked to recall as many letters as possible, with a 0-, 0.5-, or 1.0-second delay before responding. Researchers hypothesized that longer delays would result in poorer recall. The number of letters correctly recalled is given in the table.

Part A: A European firm has two options: either to operate at home in Europe and export its product to India, or to invest directly and produce in India (FDI). Say that the demand function for this product in the Indian market is p = 800 − Q , where

Q ≡ q _L + q_EU , and where q_L is the output of the local (Indian) firm and q_EU is the output of the European firm under exports or FDI (all prices are supposed to be in euros). Regarding efficiency, the European firm (wherever it is located) has to use 2 units of labor to produce one unit of output, while the Indian firm has to use 4 units of labor. Regarding factor prices, in the European labor market, the cost of labor is 20 euros for each unit of labor used, while it is only 10 euros in the Indian labor market. Competition between the Indian and the European firm is as in Cournot under both exports and FDI.

If the European firm decides to operate at home and export its goods to India, it has to pay a transportation cost of 100 euros per unit of output. On the other hand, if the European firm decides to invest directly and produce in India, it has to pay a fixed cost of 26000 euros for license and other bureaucratic costs. What is better for the European firm to do? (In your solutions, present numbers with no more than two decimal points.) (Mark: 1.5)

Part B: In no more than 200 words, discuss why firms may choose FDI instead of exports to a foreign country. (Mark 1.0)
