The kinetic energies of a light and a heavy body are equivalent. The momentum is greater for the light body.
<h3>What is momentum?</h3>
Momentum is characterized as the intensity of a body's motion. As momentum depends on both velocity and the direction of the body's motion, it is quantified by "mass velocity". Since velocity is a vector and mass is a scalar, momentum is a vector quantity.
As a result of its higher mass, a heavy object will move with more momentum. Only when the average speed of the heavy particles is lower than that of the light particles will the average kinetic energy of the light particles equal the average kinetic energy of the heavy particles.
At the same temperature and pressure, lighter gases will move more quickly than heavier ones. 0K on the Kelvin scale denotes that the particles are not moving.

What is schematic Current?</h3>
An electrical schematic is a diagram that shows how all of the wires and components in an electronic circuit are connected.
The ability to read electrical schematics is a really useful skill to have. To start developing your schematic reading abilities,
it’s important to memorize the most common schematic symbols.
Each physical component (i.e resistor, capacitor, transistor) has a unique schematic symbol.

Answer:
1. Density = 1200[kg/m^3]; 2. Volume= 0.005775[m^3], mass= 15.59[kg]
Explanation:
1. We know that the density is defined by the following expression.
![Density = \frac{mass}{volume} \\where:\\mass=90[kg]\\volume=0.075[m^{3} ]\\density=\frac{90}{0.075} \\density=1200[\frac{kg}{m^{3} }]](https://tex.z-dn.net/?f=Density%20%3D%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5Cwhere%3A%5C%5Cmass%3D90%5Bkg%5D%5C%5Cvolume%3D0.075%5Bm%5E%7B3%7D%20%5D%5C%5Cdensity%3D%5Cfrac%7B90%7D%7B0.075%7D%20%5C%5Cdensity%3D1200%5B%5Cfrac%7Bkg%7D%7Bm%5E%7B3%7D%20%7D%5D)
2. First we need to convert the units to meters.
wide = 35[cm] = 35/100 = 0.35[m]
long = 11 [dm] = 11 decimeters = 11/10 = 1.1[m]
Thick = 15[mm] = 15/1000 = 0.015[m]
Now we can find the density using the expression for the density.
![density= \frac{mass}{volume} \\where:\\volume = wide*long*thick\\volume=0.35*1.1*0.015 = 0.005775[m^3]\\\\mass= density*volume = 2700*0.005775 = 15.59[kg]](https://tex.z-dn.net/?f=density%3D%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5Cwhere%3A%5C%5Cvolume%20%3D%20wide%2Along%2Athick%5C%5Cvolume%3D0.35%2A1.1%2A0.015%20%3D%200.005775%5Bm%5E3%5D%5C%5C%5C%5Cmass%3D%20density%2Avolume%20%3D%202700%2A0.005775%20%3D%2015.59%5Bkg%5D)
-- Energy from the sun was absorbed by grass, grain, and hops, making it possible for them to grow.
-- The grass was eaten by livestock, and turned into stored beef energy.
-- The grain was harvested, pounded into flour, baked, and turned into stored bread energy.
-- The hops were harvested, soaked, and turned into stored beer energy.
-- Johannes Brahms ate beef, which his body turned into brain and muscle energy. Ludwig van Beethoven drank beer, which his body turned into energy and inspiration. John Phillip Sousa ate bread, which his body turned into leg energy to march with.
-- All of these individuals, and a lot of others, composed music which nobody had ever heard before, using the solar energy they absorbed from the stuff that they ate and drank.
