Two masses m₁ = 6 kg and m₂ = 4 kg are connected by means of a string that passes over a frictionless pulley as shown in the figure. When the masses are released, what is the acceleration of the masses? Take g = 10 ms^–2.

Vexillum is found in __________.

Two bodies A and B have thermal emissivities of 0.01 and 0.81 respectively. The outer surface area of the two bodies are the same. The two bodies radiate energy at the same rate. The wavelength λ_B, corresponding to the maximum spectral radiancy in the radiation from B, is shifted from the wavelength corresponding to the maximum spectral radiancy in the radiation from A by 1.00μm. If the temperature of A is 5802 K, then:

Statement A: The process of phloem loading is an active process.

Statement B: The process of phloem unloading is a passive process.
