A stone tied to a string is supported from a spring scale that reads 10 N. A pail of water rests on a platform scale that reads 80 N. The stone is lowered into the water and the spring scale then read?
90N
Why is the reading on the spring scale equal to the friction force in each case?
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.
How do you weigh objects on a scale?
Pu them on it and learn to read
If 2 equal weights are attached to a fish scale on each end so that the full exertion of force from the weight is transferred into the scale would the scale read the weight of 2 weight's worth or one?
if the weight is distrubted equally then the scale will read 2 weights worth
Suppose that a 50.0 kg woman were standing on a bathroom scale in this elevator car what would the scale read?
On the way up:-Before the car started moving, it would read 490 newtons (110 pounds).-When the car started moving up, the scale would read more, until the car achieved its normal upward speed.-As long as the car maintained its steady normal speed, the scale would again read 490 newtons (110 pounds).-As the car approached its destination level and began to slow down, the scale would read less, until the car stopped.-When the car stopped, the scale reading would return to its normal 490 newtons (110 pounds).On the way down:-Before the car started moving, it would read 490 newtons (110 pounds).-When the car started moving down, the scale would read less, until the car achieved its normal downward speed.-As long as the car maintained its steady normal speed, the scale would again read 490 newtons (110 pounds).-As the car approached its destination level and began to slow down, the scale would read more, until the car stopped.-When the car stopped, the scale reading would return to its normal 490 newtons (110 pounds).================================All numbers are rounded. Acceleration of gravity is taken to be 9.8 meters (32.2 feet) per second2.
What does the spring scale measure if measured in newtons?
I just read that you can weigh anything on it.

Im pregnant but he pulled out how should you tell him?
let him read the info that you have on the web and then he should understand.

What is the procedure for finding the weight using a spring balance?
Assuming you mean one that hangs from a hook, just hang the article and read the pointer on the scale.

How do I find out what 3.2 mean on a scale?
Read what the scale or the key to the scale says.

Does a spring scale measure weight?
A spring scale is any device that uses the translation of a spring by force due to weight to discover the mass of an object. Let's translate that into easier words. A spring wants to hold its shape. But it is elastic, and if we apply a force to it, it changes shape. The amount of change in its shape will be proportional to the force applied to it. That's Hooke's law of elasticity. Nothing could be simpler. How does that apply? Jump with me and we'll see. By attaching a pointer or dial to a spring in a particular way, we can use the "coefficient of elasticity" of the spring to tell us how much gravity is pulling on something (which is force). We use that something to change the shape of the spring, and by indexing the movement of that spring, that is, setting up a scale or dial, we can use the device (after calibration) to give us a fairly accurate measure of the weight of an object. Most of us are familiar with the spring scale as the so-call "bathroom scale" which is kept secreted away in the water closet. It's a spring scale, and a useful device (though there seem to be more and more electronic interlopers). There are also small versions of the spring scale, too. We find them in home kitchens for weighing food or small objects, as well as in some fishing tackle boxes. Before the electronic age, these little scales were everywhere that there was commerce. Think of all the stuff that gets weighed from meat and produce at the store to the letters and packages at the mailing places. The spring scale used to do all that. And it did it pretty well, too. Links are provided to Wikipedia articles for further reading. A device used to determine the weight of an object (usually fairly light like 10 pounds or less). It uses a spring attached to a hook to work. The object to be weighed is hung from the hook, which compresses the spring. The amount that the spring is compressed is read on a scale that is graduated in pounds.
How is A multimeter set to read DC volts on a 4 volt scale is connected to a twelve volt battery?
Use the next higher scale than the voltage you are trying to read. It should be either 20 or 30 volt DC
How do you read a ruler to the proper number of significant figures?
A ruler or scale should not be read to less than the smallest graduation. In practice, in-between measurements can be estimated but they are not significant.
