F=1000n, F=ma, a=F/m=1000n/10= 100n. a=v²/2s, v²/2s=100n, n= v²/200s=50²/200•10=1.25. The amount of explosive is 1.25•10 =12.5 kg.
physics
F=qvBsinα sinα = sin180= 0 => F=0
physics
incandescent solids produce a continious spectrum of radistion, excited gases - line spectrum
Physics
This is correct solution
Physics
ma= Fcos θ –μ(mg-Fsin θ) μ = (Fcos θ -ma)/ (mg-Fsin θ)
