Define mechanical advantage in terms of input force and output force

1 answer:

5 0

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 forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever. Hope this helps and please mark me as brainlest and like:)

The table below shows the dimensions of two colored cubes.

Lelechka [254]

Answer: The correct answer is black because the product of its side and mass is lower.

Explanation: Density of a substance is defined as the mount of matter that can be stored in a given volume.

Mathematically,

$Density=\frac{Mass}{volume}$

As, density is inversely proportional to the volume of the substance.

The substance will be more denser if it has less volume and it will be less denser if the volume is more.

We are given two cubes having different sides.

Volume of the cube is calculated by using the formula:

$V=a^3$

where, a = side of the cube.

Black: The side of this cube is 2 and volume will be = $2^3=8cm^3$

Yellow: The side of this cube is 3 and volume will be = $3^3=27cm^3
$

As, the volume of black cube is less. So, this cube will be more denser.

Density of black cube: $\frac{48}{8}=6g/cm^3$

Density of Yellow Cube: $\frac{135}{27}=5g/cm^3$

Hence, black cube will be more denser because the product of its side and mass is lower.

Describe the three components that make up the structure of the atom, including their charge and specific locations within atom.

EastWind [94]

Protons electrons and neutrons make up a atom they are the 3 components.
Electrons are negatively charged and protons are positive. Neutrons are neutral between the two. The electrons are on the outside of the atom constantly moving(outside of nucleus)the protons and neutrons are in the nucleus.
