Which device is used to measure weight?
A
Scales
B
Balance
C
Newton meter
D
All of the answers are correct
Explanation: 

Detailed explanation-1: -A spring scale, spring balance or newton meter is a type of mechanical force gauge or weighing scale. It consists of a spring fixed at one end with a hook to attach an object at the other.

Detailed explanation-2: -Weighing machine is the device used for measuring weight.

Detailed explanation-3: -The spring scale definition means a tool for measuring weight or force. Also known as a spring balance or newton meter, this device is used primarily to weigh items or objects by attaching them to a hook at the bottom of the device.

Detailed explanation-4: -A force meter, also known as a newton meter, can be used to measure the size of a force. Force meters have a spring inside them. The weight of the mass causes the spring to stretch. It is important to ‘zero’ the force meter before you use it.

Detailed explanation-5: -A Newton Meter A balance, whether digital or analogue can be used to help determine the weight of an object. The measurement from a balance will be in kg (the mass of the object). As gravity on Earth, is 10 N per kg, the measurement from the balance is multiplied by 10 to give the weight in newtons.
