Why you place object in left pan of physical balance?
Placing the object in the left pan of a physical balance allows for comparisons to be made more easily. By placing the object to be measured in one pan and known weights in the other, you can determine if the two sides are balanced or if one side is heavier than the other. This allows for accurate measurements to be taken.
Why you place an object in left pan of physical balance?
By placing an object in the left pan of a physical balance, you can compare its weight to the weights of other objects placed in the right pan. This allows you to determine the relative weight of the objects in comparison to each other, helping you to measure or compare their masses accurately.
Why an unknown mass is placed in the left pan of physical balance?
It is just for human convenience. If the person who uses the physical balance is left handed then placing the unknown mass in the right pan will be the most convenient for him. So easyness to place the weights on the pan is considered. Hence the usual procedure.
In physical balance on What pan we place the object and why?
In physical balance, an object can be placed on a pan that is supported by a pivot point, such as a fulcrum or a center of mass. This allows for equal distribution of weight on both sides of the pan, ensuring stability and equilibrium. The pan must also be level to maintain balance, with the object positioned directly above the pivot point to prevent tipping.
Why is it important to keep the balance area clean?
It is important because dust particles have a small mass and if they get onto the balance they can cause an error in the mass of the object being measured. Furthermore, if a liquid is was spilled near to a balance or on a balance and it is left there, it can cause the balance to rust and give inaccurate readings.
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.
What is the left arm pan of a platform balance used for?
The left pan of the balance can be used for counter weights. Another use might be to put an identical dish or beaker. Since taring can be error prone it would be better to counter balance.
What is the function of balancing screws 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.
Is wood and leaves that are left to rot and to form humus a chemical or physical change?
Both. In breaking down into humus, both chemical and physical change takes place.
Why must a laboratory thermometer be left in place to take a reading?
A laboratory thermometer must be left in place to take a reading because the thermometer needs time to adjust and reach thermal equilibrium with the substance being measured. Moving the thermometer too soon can result in an inaccurate reading.
How do you change the overall balance in garageband?
Garageband does not have a master balance (left/right) control. You will have to adjust the pan control for each track individually to balance the sound left/right.
What happens if you do not zero the balance before finding the mass of an object?
If you do not zero the balance before finding the mass of an object, the measurement will include the weight of any additional substances or residue left on the pan. This can lead to an inaccurate mass measurement of the object you are trying to weigh. Zeroing the balance ensures that only the mass of the object itself is measured.
