What is the minimum energy required to lift an object weighing 200 newtons to a height of 20 meters?
The minimum energy required to lift an object is equal to the work done, which is given by the formula: work = force x distance. In this case, the work done would be 200 N (force) x 20 m (distance) = 4000 joules. Therefore, the minimum energy required to lift the object weighing 200 N to a height of 20 meters is 4000 joules.
Which is more accurate direct weighing or weighing by difference?
Weighing by difference is generally more accurate than direct weighing because it accounts for any loss of material during the weighing process. Direct weighing can be influenced by factors like measurement errors or environmental conditions, which may affect the accuracy of the result.
How heavy is a weighing scale?
A weighing scale itself is not heavy, as it is designed to be easily movable and transportable. The weight of a weighing scale can vary depending on the type and size, but typically they are lightweight and can be easily carried by hand.
Who invented the first weighing scale?
The first weighing scale is said to have been invented by the ancient Egyptians around 2,000 BC. However, a more modern version of the weighing scale was developed in the 18th century by the French inventor, Richard Salter.
How does weighing by difference compare to saving pencil shavings and weighing them to see how much was shaved off?
Weighing by difference involves weighing the entire sample before and after the desired component is removed, while saving pencil shavings involves physically collecting and weighing the material removed. Weighing by difference is more accurate as it accounts for any losses that may occur during the process, such as dust. However, saving pencil shavings can provide a visual representation of the amount removed and is more suitable for larger components that are easily collected.
What is the minimum force required to prevent a ball weighing 12 lbs from rolling down a ramp which is inclined 60 degrees with a horizontal?
12 x sin 60 = 11.08 pounds
What horizontal force P is required to drag a sack of rice weighing 110 pounds. in a horizontal floor if the coefficient of friction between the floor on the sack of rice is 0.25?
The force of friction acting on the sack of rice is the product of the coefficient of friction and the normal force, which in this case is the weight of the sack (110 pounds). Therefore, the force of friction is 0.25 * 110 = 27.5 pounds. The horizontal force required to overcome this friction and drag the sack of rice is equal to the force of friction, so a force of 27.5 pounds (P = 27.5 pounds) is required.
How much force will it take to pull 200 pounds?
To pull an object weighing 200 pounds, the force required will depend on several factors, including friction and the angle of the pull. In a frictionless environment, you would need to exert a force equal to 200 pounds to overcome gravity and initiate movement. However, if there is friction, you would need to exert additional force to overcome that resistance as well. Therefore, the total force required could be greater than 200 pounds, depending on the specific circumstances.
What is the min no of weighing operations required to measure 31 kg of rice if only one stone of 1 kg is available?
32 weighing operations are required to measure 31 kg of rice with a 1 kg stone. Start by weighing 1 kg, then 2 kg, 3 kg, and so on up to 31 kg. Each weighing operation will add 1 kg to the total.
What are the benefits of using digital weighing scales?
Digital weighing scales offer high accuracy, easy readability, and multiple weighing modes, making them ideal for various industries, including retail, healthcare, and laboratories. They provide precise measurements with minimal errors, ensuring efficiency in weighing tasks. militonscale. com
