of light?
A plane is moving east at 200 km/hr. while you’re a moving west at 50 km/hr. If the frame of reference is you inside the car, describe the motion of the plane.
c) One pack of chips weighing 140 g contains 2.5% salt. Decide if Barborka was right that by eating two such packs of chips, the 65-kilogram Samo would exceed the recommended daily dose of salt. (The recommended daily dose is 100 mg per 1 kg body weight)
Potassium iodate is most often used to iodide table salt. The weight fraction of potassium iodate in table salt is 0.006%. 0.59 g of iodine is contained in 1.00 g of potassium iodate.
e) Calculate how much g of salt Samo needs to eat to cover his daily iodine requirement. Assume that Samo does not receive iodine from other sources, only through iodized table salt.
If you are riding in the backseat of a car moving 65 mph with your friend, how fast does your friend appear to be moving from your frame of reference? Explanation
a)solve dy/dx - 3ye^3x =y. Given that y=1 when x=0
b)find the solution of sinx dy/dx + y cosx = sin^3 x cosx

write a python programs that accepts three inputs x,y,z print true if x*y>z otherwise false
A new feature is to be implemented in Kindle. FEATURE : The user inputs the no. of days in which he would like to complete a particular book and the Kindle will create a reading plan for the user.
Write an algorithm which will output the reading plan to the user. The reading plan should be created keeping in mind that the user would like to begin and end reading a particular “chapter” of the book on the same day.
