WebDrag force FD is proportional to the square of the speed of the object. Mathematically, FD = 1 2CρAv2, where C is the drag coefficient, A is the area of the object facing the fluid, and ρ is the density of the fluid. Athletes as well as car designers seek to reduce the drag force to lower their race times ( Figure 6.29 ). WebAug 26, 2014 · See answer (1) Copy. Yes mass and volume are directly proportional. If density remains constant, then adding mass will force the volume to increase. If volume decreased or remained constant in ...
What relationship exists between concentration of solution and its ...
WebSep 14, 2024 · Density is defined as the ratio of mass to the amount of matter i.e. volume. The mathematical expression is given as: Now, from the mathematical expression, density is inversely proportional to volume and directly proportional to mass implies with decrease in volume, density is also decreases and with increase in mass, density is … WebThe linear density of a rod of length ‘L’ at a distance ‘x’ from one end is given by calculate the mass of rod, given λ 0 is the density of the rod at x = 0. Q. The mass per unit length of a rod of length 3 m is directly proportional to distance x from its one end. svg2jpg online
Density - Wikipedia
WebWe can say that the volume of the object is directly proportional to its mass. As the volume increases the mass of the object increases in direct proportion. WebKinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. WebDensity. Density is a measure of how much mass there is in a given volume or amount of space. The density of any substance is calculated by dividing the mass of the matter by the volume of the matter. In Fig. 2.2, volume is represented by boxes and individual particles of matter are represented by colored shapes. Box A has five spheres. brana 25 epizoda sa prevodom
