## Questions

### Subject: Calculus

Take the integral of the given function: y=3x^5+2X^3+2

The answer is: 1/2x^6+1/2x^4+2x+C C is a constant.

### Subject: Algebra

Perform the multiplication and then write it down in scientific notation: (3.2*10^(-6))*(4.1*10^13)

Since 3.2*4.1=13.12 and -6+13=13-6=7, then the answer is: 13.12*10^7 which in scientific notation converts to 1.312^10^8

### Subject: Physics

A resting disc-shaped firecracker in explodes and separates into 3 pieces and they each go in a different direction. What is the final, total momentum of the system consisting of the three parts and why?

Zero; since there is no net force being exerted on the firecracker, the change in momentum of the system is zero. Initially the system is at rest so its initial momentum is zero. Therefore the final momentum of the system must be zero as well.
