a block of ice has the density of 0.97 g/cm3 . how much of it will sink below the surface of the water?
about 97 percent of the ice will sink below water.
all—100 percent—of the ice will sink below water.
about 3 percent of the ice will sink below water.
none—0 percent—of the ice will sink below the water.

About 97 percent of the ice will sink below water.

Explanation:

Let the volume that is submerged into the water is given as V1

so at equilibrium condition we can say that buoyancy force on it is balanced by weight of the block

so we have

now we have

so the percentage of block that is submerged into the water is given as

volume percent submerged = 97 %

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
