In order to measure the mass of a body, it is necessary to find a standard mass or a combination of standard masses whose weight exceeds that of a body at the same place on earth. The device employed for this purpose is called a balance.

What is the physical quantities of compression balance?

Compression balance measures the compressive strength of a material by applying a force and measuring the resulting deformation or displacement. The physical quantities involved include force, displacement, and area of contact. It is commonly used in material testing to assess the structural integrity of materials under compressive loading.


Why is condition of equilibrium between evaporation and condensation know as a physical equilibrium?

The condition of equilibrium between evaporation and condensation is known as a physical equilibrium because it involves a balance between the rates of evaporation and condensation without any change in the chemical composition of the substances involved. The equilibrium is based on physical processes such as the balance of vapor pressure and temperature rather than chemical reactions.


Is physics involved in cheerleading?

Yes, physics is involved in cheerleading, particularly in understanding concepts like momentum, torque, rotation, and gravity. Cheerleaders use these principles to execute stunts safely and effectively, such as when calculating the force required to lift a flyer or maintain balance during complex maneuvers.


Why is physical balance used in laboratories instead of beam balance?

Physical balance is used in laboratories instead of beam balance because physical balance is more accurate and sensitive in measuring small quantities of substances. It also provides quicker and more precise results compared to a beam balance, making it ideal for scientific research and experiments where precision is key. Additionally, physical balance is easier to calibrate and maintain, ensuring consistent and reliable measurements.


What is function of balancing screws in physical balance?

Balancing screws are used to adjust the balance of the physical balance by adding or removing weight to ensure that the beam is level and accurate when weighing objects. By manipulating the position of the balancing screws, the physical balance can be calibrated to measure weights precisely.
