Why cant you just add up different isotope mass numbers and then divide by the total to calculate an average mass number?
Calculating an average mass number by adding up different isotope mass numbers and dividing by the total does not provide an accurate representation of the average mass of an element because isotopes occur in nature with varying abundances. To calculate a more accurate average mass number, the mass of each isotope needs to be multiplied by its relative abundance (expressed as a decimal) before summing them up.
Why do you do work on a bag of groceries when you pick it up but not when you are carrying it?
Because the physics definition for "Work" is using force to move a mass through a distance. Picking up the bag is using the force of your muscles to move a mass, or weight, through a distance, the distance from the grocery store counter up into your arms.
Do clay work has mass or volume?
Clay work has both mass and volume. Mass refers to the amount of matter in an object, while volume refers to the amount of space the object occupies. Clay has mass because it is made of particles, and when shaped into an object, it takes up a certain amount of space, giving it volume.
What does a mass of cells with more than one cell type make up?
A mass of cells with more than one cell type makes up a tissue. Tissues are groups of cells that work together to perform a specific function in the body.
Is it matter or energy if something cannot be seen but has mass and takes up space?
If something cannot be seen but has mass and takes up space, it is matter. Matter is anything that has mass and occupies space, which includes both visible and invisible particles. Energy, on the other hand, refers to the ability to do work or cause a change and does not have mass or take up space.
Is work done when a force is a applied to a mass but the mass does not move?
No, work is not done if the force is applied to a mass but the mass does not move. Work is only done when a force causes a displacement in the direction of the force being applied.
How velocity of an object can affect the work done by the object when moving up and inclined?
work = force * distance and force = mass * acceleration and acceleration = change in velosity/change in time so work = mass * acceleration * distance , as a result work = mass * change in velosity/change in time * distance, hence the velocity of the object affected by : 1.mass of the object. 2. gravitational acceleration which reduces the speed of the object when go up and increases the speed of the object when it come down.. 3. look at the rules etc........thx..............with best regards
What is the mass of ideas associated with a work of art?

What SI unit would best describe the mass of a 4x4 pick up truck?
The 'kilogram' would work fine.
How can you work out the value for mass?
Knowing the volume of a substance and its density you can work out the mass of that volume. Alternatively you could measure the mas using a mass balance.
How do you find distance given mass and work?
You can't. Work is (force) times (distance), so you have to know something about the force. Just knowing the mass doesn't tell you anything about the force ... unless there's actually something else about the mass that you've overlooked.
