A 20 N metal block suspended by a spring balance. A beaker containing some water is placed on a weighing machine which reads 32 N. The spring balance is now lowered so that the block gets immersed in the water. The spring balance now reads 16 N. The reading of the weighing machine will be

When you put an object on a spring balance, what do you measure ?

A boy whose mass is 50kg stands on a spring balance inside a lift. The lift starts to ascent with an acceleration of  2ms−2.2𝑚𝑠−2. The reading of the machine or balance is  (g=10 ms−2)(𝑔=10 ms−2)

Physics students use a spring scale to measure the weight of a piece of lead. The experiment was performed two times, one in air and the other in water. If the volume of lead is 50 cm3, what is the difference between two readings on the scale? Density of water is equal to 1000 kg/m³Group of answer choices500 N0.5 N5 N50 N

The apparatus is to be set up for the candidates as shown in Fig. 1.1. The spring is to be suspendedfrom the clamp, supported by a boss and stand. The spring must be sufficiently high above thelaboratory bench so that when the 1.00 N load is suspended from the spring, the bottom of theload is above the surface of the bench.3. The metre rule (supported by the clamp, boss and stand) must be near to, but not touching, thespring. The 100 cm end of the metre rule must be touching the bench

An object weighs 10 N in air. When fully immersed in water, it weighs only 8 N. The weight of the liquid displaced by the object will be:
