How do you know if the numbers on the two sides of the balance are equal?
Before you measure with it you set both sides of the balance equal to zero so then when you measure they will either equal the same or balance out.
How do you calculate urine output from weighing wet diapers?
A conventional baby scale can be used to calculate urine output. Weight the diaper before putting it on your baby, and then again when it is wet.
How do you use the equal arm balance?
Before you begin using an equal arm balance, you must make sure the riders are an equal distance apart, and make sure the balance is balanced. Then, place the object(s) on one side of the balance, and the object(s) that you want to compare them to. Whichever object is closer to the ground is heavier. If the objects are equally levelled, they have equal mass.
Same as before?
what should i do if he isnot loving same before
Should there be a comma before the word inc?
"Inc" is not a word, it's an abbreviation for "Incorporated," and there should be a comma before it.
What do you check before using a triple beam balance?
to measure the mass of objects
Why is it important to determine the rest point of the triple beam balance before using it?
You need to set the balance to zero before using it because it affects the accuracy of the measurement. Ideally, you should set the balance to zero before each weighing.
Why should you always adjust reading of a trip scale balance to zero before weighing an object?
After a timeof use it does not give you the start of zero, so you will have restart it to zero.
How long before weighing should you quit consuming liquids?
Just use the toilet before using the scale.
Was noel pointer sick before his death?

What is function of balancing screws in physical balance?
Screws help to level beam of physical balance so that both pans can be balanced before putting mass and weight in both pans. WAHEED
What is the function of screw in a physical balance?
There are two screws on the physical balance. One is on the left side and other is on the right side of the physical balance. If pointer is not in middle of the scale, we move these screws forwards or backwards to bring the pointer in the middle of the scale. This is done before we put any mass or weight in either of the pan. In other words we use the screws to remove the zero error of the physical balance.

How do improve weighing a rabbit after its been fed?
When weighing a rabbit after it has been feed the biggest improvement one might see is on the scale. The weight of the rabbit after eating should be higher than it was before eating.
Why cool the crucible before weighing?
The crucible must be cold before weighing because the heat from the crucible will warms the surrounding air
What container should be used in weighing sticky and adhesive substance?
Electronic single-pan balances with digital readouts are now favoured over mechanical types and are common in most laboratories. There are essentially two types of balance: General-purpose balances which weigh to the nearest 0.01 g with a capacity of about 300 g. Chemicals may be dispensed for weighing, into a suitable weighing container, directly onto these balances. Analytical four-figure balances for quantitative work, which weigh to the nearest 0.0001 g (0.1 mg) and have a maximum capacity of about 100 g. Chemicals must not be transferred onto the balance at any time and analytical balances must only be used for weighing by difference. Both types are illustrated in Fig. 4.3 and you should familiarize yourself with their operation before use.
What are the Name of mouse pointer shape and functions?
The upper-left pointing arrow pointer is a general-purpose pointer. It is used in most window areas for single-object selection and activation. The hotspot for the arrow pointer should be in the point of the arrow.You can optionally use an I-beam pointer in any Text component. It is used to change the location of the text insertion cursor and to perform actions on text. If the I-beam is used, it can be hidden during the time between any keyboard action and a mouse movement. This helps the user distinguish the I-beam pointer from the text insertion cursor, which can also be an I-beam. The hotspot for the I-beam pointer should be on the vertical bar of the I-beam about one-third up from the bottom.The X pointer can indicate when the pointer is outside of any application area. The hotspot for the X pointer should be where the lines intersect.The resize pointers indicate positions for area resize, and they remain during a resize operation. The direction of the arrow in the pointer indicates the direction of increasing size. The horizontal and vertical pointers indicate resize in either the horizontal or vertical direction. The diagonal pointers indicate resize in both the horizontal and vertical directions simultaneously. The hotspot for the resizing pointers should be on the elbow or the line at the position pointed to by the arrow.The hourglass pointer, a working pointer, indicates that an action is in progress in the area, and that the pointer has no effect in the area. While the hourglass pointer is active, all mouse button and keyboard events are ignored in the area. The hotspot for the hourglass pointer should be located at the center of the hourglass, although it should not be used for activation. The hourglass pointer can be used interchangeably with the watch pointer.The watch pointer, a working pointer, indicates that an action is in progress in the area, and that the pointer has no effect in the area. While the watch pointer is active, all mouse button and keyboard events are ignored in the area. The hotspot for the watch pointer should be located at the top of the watch, although it should not be used for activation. The watch pointer can be used interchangeably with the hourglass pointer.The 4-directional arrow pointer indicates a move operation is in progress, or a resize operation before the resize direction has been determined. During a move operation, the object, or an outline of the object should move to track the location of the pointer. During a resize operation, the pointer is used to indicate a direction for resizing. The 4-directional arrow pointer should change to the appropriate resize arrow when the resize direction is determined, either by crossing an object boundary with the pointer or by pressing a keyboard direction key. The hotspot for the 4-directional arrow pointer should be at the spot where the arrows intersect.The sighting pointer is used to make fine position selections. For example, in a drawing program it can be used to indicate a pixel to fill or the connecting points of lines. The hotspot for the sighting pointer should be at the spot where the lines intersect.The caution pointer is used to indicate that action is expected in another area before input can be given to the current area, and that the pointer has no effect in the area. While the caution pointer is active, all mouse button and keyboard events are ignored in the area. The hotspot for the caution pointer should be located at the center of the caution symbol, although it should not be used for activation.The question pointer is used to request an input position or component from the user. This is often used to input an object for interactive help. The user requests interactive help, then the question pointer is displayed to allow the user to indicate what position or component help is requested for. The hotspot for the question pointer should be at the bottom of the question mark.You can optionally use an arrow pointing to the upper-right corner to indicate a pending Menu action. This shape indicates that a Menu is popped up or pulled down and waiting for a Menu item to be activated or the Menu to be removed. The hotspot for this arrow pointer should be in the point of the arrow.
