In matlab how do i assign a certain value in the matrix to be changed depending on which sphere option is chosen in the menu then also display it for both volume and specific gravity when printed.

here is the question:

most materials expand as their temperature increases. one way to quantify this is with the volumetric coefficient of thermal expansion (α) [inverse kelvins, k-1]. to calculate the change in volume of an object, you can use :

∆v = α v ∆t

where ∆t is the change in temperature, and v is the initial volume. thus the new volume after a temperature change is the initial volume plus ∆v.

part a: create the variable sphdata containing the matrix shown:

0.9 51 101

1.7 42 88.1

1.5 87 133

0.8 54 76.2

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
