Which statement is true about a triple beam balance, and a spring scale?
A triple beam balance and a spring scale are two different types of measuring instruments used in physics and chemistry experiments.
1. Triple beam balance: This device is used to measure the mass of an object. It consists of a beam that is supported by a fulcrum, with three different sliding weights on one side and a pan on the other side where the object to be measured is placed. The balance achieves balance when the lever is level. The reading can be obtained by adding the values indicated by each weight.
2. Spring scale: This instrument is used to measure the force or weight of an object in Newtons. It consists of a coiled spring that stretches or compresses when a force is applied. The amount of stretching or compression is directly proportional to the force exerted on it. The reading is obtained from the scale on the spring, which measures the force in Newtons.
Based on the descriptions above, the true statement about a triple beam balance and a spring scale is that they are both used for measuring different physical quantities. The triple beam balance measures the mass of an object, while the spring scale measures the force or weight of an object.
A triple beam balance and a spring scale are two different types of weighing instruments. Here are some true statements about both:
Triple Beam Balance:
1. A triple beam balance is a mechanical weighing instrument that uses a pan, three beams with sliding weights, and a pointer to measure the mass of an object.
2. It is commonly used in laboratories and educational settings to measure the mass of smaller objects.
3. The measurement unit on a triple beam balance is usually grams (g).
4. It provides a more accurate measurement of mass compared to a spring scale.
5. The triple beam balance measures the gravitational force acting on an object.
Spring Scale:
1. A spring scale is a mechanical weighing instrument that uses a spring and a hook to measure the force applied to it by an object's weight.
2. It is commonly used for measuring the weight of larger objects, such as fruits, vegetables, and luggage.
3. The measurement unit on a spring scale is usually newtons (N) or pounds (lb).
4. The spring scale measures the force exerted by an object due to its weight.
5. It provides a general measurement of weight but may not be as precise as a triple beam balance for measuring mass.
In summary, a triple beam balance is used for measuring mass with greater accuracy, while a spring scale is used for measuring weight.
