Introduction:
When Sun burns all the hydrogen in its core, the thermonuclear reaction stops which result in the unbalanced inward gravity force and the star starts compressing inward. The contraction of the Sun leads to an increase in the collision rate, thus results into the rise in temperature in the star, at a certain point, the temperature becomes high enough in the core to launch helium burning, later when Sun runs out of helium; it gives a large burst, and this temperature is high enough to ignite the thermonuclear reaction that converts helium into carbon. Due to the formation of carbon, the huge amount of energy is liberated and Sun will expand in size and appear red giant star. When all the carbon in the star cools down with time and this result into a formation of a dying star called white dwarf.

- You're on an interplanetary mission, in an orbit around the Sun. Suppose you make a maneuver that brings your perihelion in closer to the Sun but leaves your aphelion unchanged. Then you must have Question 2 options: sped up at perihelion sped up at aphelion slowed down at perihelion slowed down at aphelionarrow_forwardThe force of the quadriceps (Fq) and force of the patellar tendon (Fp) is identical (i.e., 1000 N each). In the figure below angle in blue is Θ and the in green is half Θ (i.e., Θ/2). A) Calculate the patellar reaction force (i.e., R resultant vector is the sum of the horizontal component of the quadriceps and patellar tendon force) at the following joint angles: you need to provide a diagram showing the vector and its components for each part. a1) Θ = 160 degrees, a2) Θ = 90 degrees.
