1. [4 marks] Every morning, a boy scout raises a flag with a mass of 1.5 kg to the top of a 15.0 m flagpole. How much work is done by the scout?

work = force * distance

soo...

Step-by-step explanation:

force = mass * gravity

(1.5 kg )*(9.8 m/) = 14.7 kgm/  or Newtons  

W = 14.7 N * 15 m = 220.5 Nm  and since 1  N = 1 Joule

we say  220.5 Joule  

220.5 J   :)

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
