Answer:
The total displacement is 102 km north of east.
Explanation:
We can treat this problem as a trigonometric one, so we need to calculate the total displacement on the north and east.
and
The total displacement is given by:

Type-Ia supernovae are probably thermonuclear explosions of accreting white dwarfs that have approached or reached the Chandrase
khar limit. a. Use the virial theorem to obtain an expression for the mean pressure inside a white dwarf of mass M and radius R. b. Use the result of (a) to estimate, to an order of magnitude, the speed of sound, vs = p dP/drho ∼ p P/rho, inside a white dwarf. In an accreting white dwarf with a carbon core that has reached nuclear ignition temperature, a nuclear burning "flame" encompasses the star at the sound velocity or faster. Within how much time, in seconds, does the flame traverse the radius of the white dwarf, assuming R = 104 km, M = 1.4M¯? Note that this soundcrossing timescale is ∼ (Grho) −1/2 , which is also the free-fall timescale (Eq. 3.15.)

b. 2.5 seconds
Explanation:
Chandrasekhar limit:
The Chandrasekhar limit can be seen as the maximum mass of a stable white dwarf star. The currently accepted value of the Chandrasekhar limit is about 1.4 M (2.765×1030 kg).
Using the information above, kindly check attachment for details of the solution.
