Question

(1) Which of the following will float or sink in water?
Density of water = 1 gem”)
a. A body A having density 520 kgm-
b. A body B having density 2520 kgm-
c. A body C having density 1100 kgm

Pls answer fast I really need this answer

Answer 1

Answer:

Solution:

(a) body A having density 500 kg\ m^{-3}

= 500\times\frac{1}{1000}=0.5\ g\ cm^{-3}

Therefore, density of body A is less than density of water hence A will float.

(b) body B having density 2520 kg\ m^{-3}

= 2520\times\frac{1}{1000}=2.52\ g\ cm^{-3}

Therefore, density of body B is more than density of water hence B will sink.

(c) body C having density 1100 kg\ m^{-3}

= 1100\times\frac{1}{1000}=1.1\ g\ cm^{-3}

Therefore, density of body C is more than density of water hence B will sink.

(d) body D having density 0.85 g\ cm^{-3}

Density of body D is less than the density of water hence body D will float.

Answer 2

Answer:

body A and D will float while body B and C will sink
