Astudent in an undergraduate physics lab is studying archimede's principle of bouyancy. the student is given a brass cylinder and, using a triple beam balance, finds the mass to be 3.21 kg. the density of this particular alloy of brass is 8.62 g/cm 3 . the student ties a massless string to one end of the cylinder and submerges it into a tank of water where there is an apparent reduction in the weight of the cylinder. with this information, calculate the volume, v , of the cylinder and the tension, t , in the string when it is submerged in the tank of water. the density of water is 1.00 g/cm 3 , and the acceleration due to gravity is gvolume of the cylinder: cm3tension in the string: n

Can somebody explain to me how newton's 3rd law relates to momentum? ~ap physics 1

Why do electron microscopes have higher resolving power than light microscopes?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
