You need to determine the density of a ceramic statue. if you suspend it from a spring scale, the scale reads 28.4 n. if you then lower the statue into a tub of water so that it is completely submerged, the scale reads 17.0 n. for the steps and strategies involved in solving a similar problem, you may view a video tutor solution.

Explanation:

Suppose g = 9.8 m/s2. When the statue is suspended from the spring scale, the scale reads 28.4 N. This means the mass of that statue is:

When the tub is lowered and submerged in water, the scale reads 17N. So the statue is subjected to a force that make the difference of 28.4 - 17 = 11.4N. This equals to the gravity force of water displaced.

Let water density , we can calculate the volume of the water displaced, which is also the volume of the statue:

The density of the statue is mass divided by its volume:

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
