Are you using British or American pennies. I have access to neither, but suspect you do. Just weigh a few - say ten; and that'll give you a good idea of their weight.
you can make 40 cents withiut using pennies 7 ways
None. If you "get 65 cents using only dimes nickels and quarters" you are not using any pennies!
1 dime 2 nickels 1 nickel, 5 pennies 10 pennies
40 pennies 8 nickles 2 dimes
Using pennies, nickels, and dimes: 85 pennies 1 nickel 1 dime Total = 87 coins.
When you pull on the scale you stretch the spring the pointer on the scales moves as you pull to measure the force you are using you have to be able to lift or pull on the spring scale
I just read that you can weigh anything on it.
It measures by using newtons.
Force. Often Measured in Newtons (N).
one very important spring scale rule is never go past the limit of newtons it can go up to.
If you're doing the weighing on Earth, then 7.09 grams of mass weigh 1/4 ounce.
A spring balance is a device wherein an object to be weighed is attached to the end of a helical spring. Gravity is a factor in using this calibrated scale.
A scale is a force indicator. The reading on a scale is simply telling you what force is being applied. If you try dragging an object across the floor using a spring scale, you are applying a force to the spring scale which is applying a force to the object. The spring scale cannot put more force on the object than you are putting on the scale, and it has to put all of the force that you put on it on the object you are pulling. The only other force on the object besides your pulling force is friction. If the object is traveling at a constant velocity, the forces on it are equal. That means that your pulling force has to equal the force of friction. The scale that you are using will read the amount of force you are putting on the object which will tell you how much friction is pulling backwards on the object because these forces are equal strengths.
The SI units of force are newtons. They're generally measured using something like a spring scale.
A kitchen device used to measure the weight of ingredients and other food. Kitchen scales are available in balance or spring models. A balance scale will give a more accurate reading than a spring scale. Using a scale will result in a more accurate measurement of the ingredients than by measuring it by volume. Scales are available in manual and digital models.
The gravitational force varies by earth density and altitude.
A newton metre is the SI unit for torque, symbol Nm, and is also technically equivalent to the joule. A newton meter is a term sometimes used to reference a spring scale, which uses a spring and Hooke's law to measure the force exerted in a linear direction. For purposes of avoiding confusion, using the term 'spring scale' is better.
