What is a median in math?

What is a median in math? The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. Median is the middle number in a sorted list of numbers. To determine the median value in a sequence of numbers, the numbers must first be sorted, or arranged, in value order from lowest to highest or highest to lowest. If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above. If there is an even amount of numbers in the list, the middle pair must be determined, added together, and divided by two to find the median value. The median is sometimes used as opposed to the mean when there are outliers in the sequence that might skew the average of the values.  You may like What is manifesting? What is electric Charge?

When you open the gas cylinder used for cooking, which action takes place first diffusion or effusion?

When you open the gas cylinder used for cooking, which action takes place first diffusion or effusion? The pressures of the ingredients of body spray inside and outside of the container are not the same. The pressure is greater inside the container. When the molecules of the gas come out through small pores into a low-pressure zone from a high-pressure zone, effusion happens. Due to the application of pressure, the molecules present in body spray come out through the small pores. The spontaneous movement is blocked by the pore of the container. The bigger the pore size, the more spontaneous the movement is. When the condition becomes absolutely pressure-less, it becomes diffusion. So in the case of a body spray, first effusion takes place, then diffusion happens. You may like Do I need car insurance? What is car insurance? How could I get cheaper car insurance?

Why is convex mirror called a diverging mirror?

Why is a convex mirror called a diverging mirror? If the convex surface of a sphere acts as the reflector, that is if the regular reflection of light takes place from the convex surface of the spherical mirror, then it is called a convex mirror.  The convex mirror is a diverging mirror since the parallel beam of light diverges from a point on spreads over and never meets at a point after reflection.

Conditions of floatation and immersion of a body?

Conditions of floatation and immersion of a body? The conditions of the floating or sinking of an object are - a) If W 1 >W 2 , or if the weight of the object is more than the liquid abstracted by the object then the object will sink in the liquid. b) If W 1 >W 2 , or if the weight of the object is equal to the liquid abstracted by the object then the object will float in a completely submerged state. c) If  W 1 < W 2 , or if the weight of the object is less than the liquid abstracted by the object then the object will float in a partially submerged state.

What is Buoyancy?

What is called Buoyancy? The ability of a fluid to exert an upward force on an object that is immersed in it called buoyancy. The upward force that liquid or gaseous matter applies perpendicularly on an object partially or completely submerged in the liquid or gaseous matter is called buoyancy.

How can you understand that a slide callipers has an instrumental error?

How can you understand those slide calipers has an instrumental error? Kinetic theory of molecules is based upon these postulates: Any substance is made of numerous small particles. These are known as molecules. Molecules are so small that they are considered point-like. The particles are always moving. In the case of gases, the molecules remain very distantly, so it can be said that they do not feel any attractive or repulsive force. In the case of liquid, though they remain away from each other, they face the shape of the container. For solid objects, they remain close as they face a strong attraction force, and thus they have their own shape and size. For gases and liquids, the particles move randomly as they collide with each other and the wall of the container.
