To solve this problem we will first proceed to find the volume of the hemisphere, from there we will obtain the mass of the density through the relation of density. Finally the mass of the stone will be given between the difference in the mass given in the statement and the one found, that is
The volume of a Sphere is
Then the volume of a hemisphere is
With the values we have that the Volume is
Density of water is
And we know that
So the net mass is
Therefore the mass of heaviest rock is 132.17g or 0.132kg
Answer:
Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact.
i think so
Answer:
0.07142 m/s in the opposite direction of the bullet
Explanation:
= Mass of rifle = 70 kg
= Mass of bullet = 0.01 kg
= Velocity of rifle
= Velocity of bullet = 500 m/s
As the momentum of the system is conserved
The recoil velocity of the rifle is -0.07142 m/s
The negative sign shows the opposite direction of the rifle.
