Question

A 0.400 kg brick of copper is heated from 295 K to 325 K. How much heat is
absorbed by the iron ?
​

Answer 1

Physics

PhysicsBlock 1, of mass m1 = 0.650kg , is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2, as shown. For an angle of θ = 30.0∘ and a coefficient of kinetic friction between block 2 and the plane of μ = 0.400, an acceleration
