3 forces acts on a 10kg mass . The first force pulls with 60N bearing 40°. The second force pulls with 80N, 60S of E. The remaining force pulls 100Non a bearing 290°. Determine the displacement of the mass 12s after moving from rest[0.14km, 35°N of W

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

An initially unpolarized light if intensity 500 w/m^2 passes through four polarizers. the transmission axis between adjacent polarizers is 45∘. what percentage of the initial intensity is transmitted by the system?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
