Question

THE ONE WHO ANSWERS FIRST WILL BE MARKED AS BRAINLIEST!!!!
Two spheres A and B, each of volume 100 cm3 are placed on water (density = 1.0 g cm3).
The sphere A is made of wood of density 0.3 g cm-3 and the sphere B is made of iron of density 8.9 g cm-3.
(a) Find:(i) The weight of each sphere, and(ii) The upthrust on each sphere.
(b) Which sphere will float? Give reason

Answer 1

Answer:

Weight of wood =30gm

Weight of iron =890 gm

Wood will float because it's density is low than that of water.

Explanation:

Density=mass/volume

0.3 g/cm-3=m/100 g/cm-3

Mass of wood =0.3×100 gm

=30 gm

Similarly mass of iron will also be calculated

Thankyou
