A graduated cylinder contains 20.0 mL of water. An irregularly shaped object is placed in
RideAnS [48]

Answer:

7.17 g/mL

Explanation:

Density = Mass / Volume

Given mass of object : 80.4g

We are not given the objects volume, however we are given that when put inside of a container with 20.0mL water, the level of the water rises to 31.2 mL.

31.2 - 20 = 11.2

The water level rose 11.2 mL when the object was placed inside of the cylinder containing the water therefore the object has a volume of 11.2mL

Now to find it's density

recall that density = mass / volume

mass = 80.4 and volume = 11.2mL

so density = 80.4/11.2 = 7.17 g/mL

Which of the following equations expresses the work-kinetic energy theorem?
Anna71 [15]

Answer:

W = ΔKE = 1/2mv₂⁽²⁾ - 1/2mv₁⁽²⁾

Explanation:

Work means Change In Kinetic Energy.

Kinetic-Energy is equal to change in velocity multiplied by mass and divided by 2

∴ KE = 1/2m²

Change in Kinetic-Energy =KE₂ - KE₁

                                             =1/2mv₂⁽²⁾ - 1/2mv₁⁽²⁾

AlekseyPX

Explanation:

Bohr built on Nicholson's idea by adopting the requirement that the angular momentum can have only certain discrete values related to Planck's constant. However Bohr's atom has many orbits for the electrons.
