What is the mass of a steel cylinder that has a density of 75.0 g/ml and a volume of 12 ml?
liubo4ka [24]
Density can be calculated using the following rule:
Density = mass / volume

Therefore:
mass = density * volume

We are given that:
Density = 75 g/ml
volume = 12 ml

Substitute with these givens in the equation to get the mass as follows:
mass = density * volume
mass = 75 * 12
mass = 900 g

What is thermal expansion?
Charra [1.4K]
Thermal expansion<span> is the tendency of matter to change in shape, area, and volume in response to a change in temperature, through heat transfer. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases.</span>

Which of the following best describes how soil is formed?
harkovskaia [24]

Answer:

Soil minerals form the basis of soil.

Explanation:

They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.

51.7ml at 27 Celsius and 90kpa to stp
never [62]
STP is the abbreviation of standard condition for temperature and pressure which is 273.15K temperature and 1.013× 10^5 Pa pressure. Since the pressure and temperature changes, I assume the question would ask about the result of the volume. The temperature used in ideal gas should be Kelvin, so 27 Celcius would be 300.15K.
The calculation would be
PV=T
V=T/P

V2/V1= T2*P1/T1*P2
V2/V1=273.15K*  90^10^3Pa/ 300.15K *  1.013× 10^5 Pa
V2= 0.81904 * 51.7ml
V2= 42.34ml

Which option defines kinetic energy?(1 point)
MAVERICK [17]

The option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion

The correct answer choice is option c

In order words, kinetic energy is that type of energy which a body or an object posess due to its relative motion.

<h3>What is energy?</h3>

Energy can simply be defined as the capacity of doing work.

Energy is a derived quantity; meaning that it is obtained from the combination of fundamental quantities.

The unit of energy joules.

Other examples of derived quantities just like energy too are:

  • Volume
  • Speed
  • Acceleration
  • Density.
  • Upthrust
  • Momentum
  • Momentum
  • Power
  • Pressure
  • Force

Below are some few forms of energy; these are:

  • Kinetic energy
  • Potential energy
  • Mechanical energy
  • Solar energy
  • Light energy
  • Chemical energy

So therefore, the option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion
