Explanation:
Ok?
The question is incomplete. The mass of the object is 10 gram and travelling at a speed of 2 m/s.
Solution:
It is given that mass of object before explosion is,m = 10 g
Speed of object before explosion, v = 2 m/s
Let
be the masses of the three fragments.
Let
be the velocities of the three fragments.
Therefore, according to the law of conservation of momentum,


So the x- component of the velocity of the m2 fragment after the explosion is,

∴ 
Reflection from such a rough surface is called diffuse reflection and appears matte
Your answer is C) The speed of sound is higher in solids than in liquids.
Your answer will be False because wavelengths are usually are use as sound waves.
