equation for speed of sound in a medium: c=sqrt(B/rho) B=bulk modulus rho=density all else being constant, and increase in temperature will cause an expansion (usually) of the material. The expansion will decrease the density (mass per unit volume) and thus increase the speed of sound through the material.
an object is more dense if there is more weight in the same area, its because of the amount of particles and the weight of the particles. eg, 1cm cubed of gold would weigh alot more than 1cm cubed polystyrene, so gold is more dense
density is the product of mass and volume so its density will b 100 g/cm3..
Not necessarily, it would depend on the density of the object. Density = mass / volume. So, you could have something like this. Density of A = 10 g/mL, volume of A = 1 mL. Density of B = 1 g/mL, volume = 5mL. The volume of A < B, however, the mass of A > B.
Formula for Buoyant Mass m(b) m(b) = m(object) x (1- (p(fluid)/ p(object))) m(object)= true mass of the object p(object)= average density of the object p(fluid)= average density of the surrounding fluid If the fluid density is greater than the average density of the object, the object floats. If less, the object sinks. Formula for Buoyant Force: F(buoyant) = -pVg p = density of the fluid V = volume of the object being submerged g = standard gravity on Earth (~ 9.81 N/kg) Archimedes Principle: "When a solid body is partially or completely immersed in water, the apparent loss in weight will be equal to the weight of the displaced liquid." Formula for Density of immersed object relative to the density of the fluid object is immersed in: Relative Density = Weight / (Weight - Apparent Immersed Weight)
the density will be greater at point B because my mommy says
at point A
It depends on the material and the location of points a and b.
The answer depends on where points b and c are!
the heat makes the density less or more dence depending were it is in the earths layers
The temperature increases the deeper you go. For earth, the hottest area of the mantle is just before you hit the core. Here it's around 4,000 °C (7,230 °F).
object B has greater density recall the formula for density is = mass/volume since volume is the same, a greater mass will give a greater density
The answer may just depend on what points B and C represent, don't you think?
B
B/c the density of the ice cube is greater than the density of the air.
The temperature of the mantle is greater at Point B than Point A. The temperature of the mantle is determined by its depth which is greater at Point B than Point A. The deeper the mantle the hotter and more pressurized it is and so the temperature at Point B will be greater than at Point A.Temperature can also be affected by other factors such as the composition of the mantle and the presence of radioactive elements. In this case since both points are in the same area and have similar composition the temperature will be determined by the depth.To summarize the temperature of the mantle is greater at Point B than Point A because it is deeper and thus more pressurized and hot.
The density of rock B is greater because its volume is less.
