Answer:

4.1 cm³

Explanation:

When multiplying, the product must have the same number of significant figures as the factor with the least number of significant figures.  0.0041 has two significant figures, 2.00 has three significant figures, and 501 has three significant figures.  The answer will have 2 significant figures.

0.0041 cm  ×  2.00 cm  ×  501 cm  

=  4.1082 cm³

≈  4.1 cm³

one side of a cube measures 0.53 cm. the mass of the cube is 0.92 g. what is the density of the cube
ziro4ka [17]

Answer:

6.17 g/cm³

Explanation:

Data given:

one side of cube = 0.53 cm

mass of the cube is 0.92 g

density of the cube = ?

Solution:

First we will calculate for volume the cube

As we know all the sides or edges of a cube are equal so volume equation will be

So,

    V = length x width x height

    V = e³

as on side = 0.53 cm

then

     V = (0.53 cm)³

     V = 0.149 cm³

Now we will calculate density of cube

To calculate density, formula will be used

             d = m/v . . . . . (1)

where

d = density

m = mass

v = volume

put values in above formula 1

                   d = 0.92 g / 0.149 cm³

                   d = 6.17 g/cm³

so. the density of cube = 6.17 g/cm³

Explain how Bohr's model built on the ideas of Einstein and Planck.
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.
