The mechanical advantage of a device refers to

Chemistry
1 answer:
Savatey [412]3 years ago
4 0

Answer:

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.

Use the dichotomous key below to identify the cell type.
xenn [34]

The dichotomous key is not given here, however, the correct dichotomous key is as follows:

step- 1a cell has a nucleus and organelles - go to step 2

        1b cell has no nucleus or organelles - bacterial cell

step- 2a cell has a cell wall - go to step 3

         2b cell has no cell wall - animal cell

step-  3a cell has chloroplasts - plant cell

3b cell has no chloroplasts - fungal cell

Using this dichotomous key the cell can be identified as - Fungal cell.

A dichotomous key is an essential scientific tool that is used to find out the various kinds of organisms on their observable traits. Dichotomous keys have a series of statements with two different choices in each step that will take the student or user to the correct identification.

Identification of the given cell:

1. Follow step 1.

  • If cells have a nucleus and organelles - yes then go to step 2

2. follow step 2.

  • 2a. if cell has a cell wall - yes go to step 3

3. follow step 3.

  • 3a. if cell has chloroplasts - no then fungal cell

Fungal cells have a nucleus and cell organelles enclosed with a cell wall around the plasma membrane but do not have chloroplast.

Thus, Using this dichotomous key the cell can be identified as - Fungal cell.

The density of a gold nugget is 19.3 g/cm3. If the volume of the gold nugget is 0.00369 L the mass of the nugget is
Sauron [17]

Answer:

The answer to your question is 71.22 g

Explanation:

Data

Density = 19.3 g/cm³

Volume = 0.00369

mass = ?

Formula

Density = \frac{mass}{volume}

Solve for mass

mass = density x volume

Process

1.- Convert volume from liters to cubic centimeters

                 1 l ----------------  1000 cm³

             0.00369l ---------   x

                x = (0.00369 x 1000 ) / 1

                x = 3.69 cm³

2.- Substitution

       mass = 19.3 x 3.69

3.- Simplification and result

       mass = 71.22 g

Part a what are the electron and molecular geometries, respectively, for the carbonate ion, co3 2−?
san4es73 [151]

The electronic geometry for the carbonate ion, in CO₃²⁻ is trigonal planar, and molecular geometry will be trigonal planar.

The electronic geometry = Total number of atoms + lone pair around the central atom

= 3 atoms + 0 lone pair

= sp₂ (trigonal planar)

The molecular geometry = As there is no lone pair its geometry will be trigonal planar.
