What happens to the volume of a loaf of bread that is squeezed? … When the loaf of bread is squeezed, the volume of the bread is reduced. Since mass remains the same, a decrease in volume increases the density of the bread.
Which is denser an object that has a density of 1000 kg m3 or one that has a density of 1 g cm3?
Which is denser: an object that has a density of 1000 kg/m3 or one that has a density of 1 g/cm3? They are the same density.
Why do we say that a spring is elastic why do we say that a blob of putty is inelastic?
Why do we say that a blob of putty is inelastic? When deformed, it does not return to its original shape. A spring is elastic up to the limit and inelastic above it.
Why do we say that a spring is elastic?
A weight hanging on a spring stretches the spring. An additional weight would stretch it further. If the weights are removed, the spring returns to its original length. Therefore, we say that the spring is elastic.
Does the strength of a person’s arm depend more on its length or its cross sectional area?
Does the strength of a person’s arm usually depend on the length of the arm or on its cross sectional area? The strength depends on the cross sectional area.
What will these objects do in water an object denser than water an object less dense than water an object that has the same density as water?
Students should realize that if an object weighs more than an equal volume of water, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.
How does this affect the amount of food each creature eats?
How does this affect the amount of food each creature eats? The greater amount of radiating area per body weight of a mouse means that it radiates a grater amount energy per body weight, which in turn means the small creature needs a greater proportion.
What happens to the volume of a loaf of bread that is squeezed what happens to the mass of the squeezed bread What happens to the density of the squeezed bread quizlet?
What happens to the volume of a loaf of bread that is squeezed? The mass? When the loaf of bread is squeezed, the volume of the bread is reduced. Since mass remains the same, a decrease in volume increases the density of the bread.
How would the block’s acceleration change if you doubled the mass of the block but kept the rocket’s force the same?
If the net force acting on an object doubles, its acceleration is doubled. If the mass is doubled, then acceleration will be halved.
What happens to the density of a uniform piece of wood when we cut it in half?
When a uniform piece of wood is cut in half, its density stays the same. The cut piece of wood has half the mass (or half the weight), but it also has half the volume. Density = mass (or weight) divided by volume.
What happens when spring passes the elastic limit?
Once a material has gone past its elastic limit, its deformation is said to be inelastic. The higher the spring constant, the stiffer the spring. When an elastic object is stretched beyond its limit of proportionality the object does not return to its original length when the force is removed.
What happens when a spring is stretched?
When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position. The force a spring exerts is a restoring force, it acts to restore the spring to its equilibrium length.
What is K in F KX?
F=−kx. where: x is the displacement of the spring’s end from its equilibrium position (a distance, in SI units: meters); F is the restoring force exerted by the spring on that end (in SI units: N or kg·m/s2); and. k is a constant called the rate or spring constant (in SI units: N/m or kg/s2).
What attaches the arm muscles to the bone?
There are tendons in your elbow that attach muscle to bone. The important tendons of the elbow are the biceps tendon, which is attached the biceps muscle on the front of your arm, and the triceps tendon, which attaches the triceps muscle on the back of your arm.
What happens when an object is denser than water?
If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.
How does the volume of a completely submerged object compare with the volume of water displaced?
How does the volume of a completely submerged object compare with the volume of water displaced? The volume of the completely submerged object is equal to the volume of displaced water. The buoyancy force is equal to the weight of the water displaced.
Why do denser objects sink?
If the object is denser than water it is more massive than the water that it displaces. This means that the object experiences greater gravitational force than the water and so sinks.
