A block of mass M1 = 4kg on a smooth inclined plane of angle - 30 is connected by a cord over a fnctionless pulley to a second block of mass M2 = 5 kg . Calculate (1) the acceleration with which the blocks move and (ii) the tension in the cordi g=10 m/s^2.​

a= 5.5 m/s^2

T= 22.2 N

Explanation:

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
