A brick suspended in air by a spring scale has measured mass of 9 kg when the brick is submerged in water the scale reads 3 kg what is they density of the brick?

The weight of the displaced water is 2/3 the weight of the brick.
So the weight of the brick is 3/2 the weight of an equal volume of water ...
just another way of saying that the density of the brick is 1.5 gm/cm3.

How is a spring used to measured a force?
Spring was used to measure a force by the balance measures the weight of an object by opposing the force of gravity with the force of an extended spring.
What are the 4 example of bodies performing simple harmonic motion?
Pendant in a clock Swing Suspended spring with mass attached An object moving back and forth between rubber buffers along an air track
What is the spring constant of a spring?
The ratio of force applied to how much the spring streches (or compresses). In the SI, the spring constant would be expressed in Newtons/meter. A larger spring constant means the spring is "stiffer" - more force is required to stretch it a certain amount.
What is a spring caliper used for?
There is no spring caliper.
What is the length of the spring when a weightof 10n hangs from it?
depends on the initial length of the spring, and how much force is required to stretch the spring
What are 3 key words related to suspension?
- the grain size of the suspended particles - the concentration of the suspended particles - the density of the suspended particles - the nature of the liquid (density, viscosity)
What are the release dates for The Thing About Jane Spring - 2009 SUSPENDED?
The Thing About Jane Spring - 2009 SUSPENDED was released on: USA: 2009
If a certain spring stretches 10 cm when a load of 12 N is suspended from it how much will the spring stretch if it is cut in half and 12 N is suspended from it?
If the spring is cut in half, it will have half the original stiffness. So, when 12 N is suspended from the cut spring, it will stretch twice as much as before - 20 cm.
Is measured using spring scale?
Weight is measured using a spring scale, which operates on the principle of Hooke's law that the force exerted on the spring is proportional to the displacement of the spring. The spring scale measures weight by the amount of force needed to stretch the spring within the scale.
What is the density of spring steel?
The density of spring steel is typically around 7.85 g/cm³.
A certain spring stretches 6 cm when a load of 15 N is suspended from it How much will the spring stretch if 30 N is suspended from it and it doesn't reach its elastic limit?
It will stretch 6 cm.
What force is measured with a spring force?
newton meter
If a certain spring stretches 4cm when a load of 10N is suspended from it how much will the spring stretch if it is cut in half and 10N is suspended from it?
If the spring is cut in half, its stiffness will increase and it will stretch less for the same load. The new stretch will depend on the new stiffness of the spring. Without knowing the exact stiffness of the original spring and the new one, it is difficult to determine the exact stretch without calculations.
Why does the suspended spring stretch more at the top than at the bottom?
The spring stretches more at the top when suspended because the gravitational force acting on the spring is greater at the top due to the weight of the spring itself. This leads to larger elongation at the top compared to the bottom of the spring.
What measured weight and mass?
A balanced scale, which compares the mass of one object with that of another.Mass is measured by physical balance.Weight is measured by a spring balance.
Do a spring scale measures mass?
Weight is the property measured by a spring scale. That is Mass X Acceleration.
Why is mass measured by spring balance is not constant everywhere?
because
