### 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?

### 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 the cause of floating and sinking of a solid body?

What is the cause of the floating and sinking of a solid body? If an object is put into still water and the amount of replaced water by the object is less than the object's mass it will drown, if the replaced water has the same mass as the object it will float while its body will be fully drowned. Again, if the amount of replaced water is more than the object's mass it will float while a part of its body is drowned.

### 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.

### What is elasticity?

What is elasticity? If an external force is applied to an object and it changes or tries to change the shape and size of the object, the property of the object that obstructs this tendency of deformation, and if the force is taken away the object regains its original size and shape is elasticity. Those objects that have this property are known as elastic bodies. You may like Steel is more elastic than rubber - Explain. What is limit of elasticity? Steel is more elastic than rubber - Explain.

### Three states can be observed due to objects floating and immersion

Three states can be observed due to objects floating and immersion If objects weight is greater than the buoyancy of liquid than the object will immerse. If objects weight is equal to the buoyancy of liquid than the object will float immersing whole in the water. If objects weight is lesser than the buoyancy of liquid than the object float while immersing partially. In this case, objects weight is lesser than the displaced liquid.

### 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.

### Why can real image not be formed by convex mirror?

Why can a real image not be formed by a convex mirror? If light rays emitted from a point after being reflected or refracted on a surface actually converge at a second point, then the second point is called the real image of the first point. The convex mirror is a diverging mirror since the parallel beam of light diverges from a point or speeds over and never meets at a point after reflection. So, a real image cannot be formed by a convex mirror. You may like Why is the Galilean-Newtonian age known as the golden age of science? Studying physics is great mental training - why was it said?

### Explain the acceleration of an object moving in a circular path.

Explain the acceleration of an object moving in a circular path. As an object moves in a circle, it is constantly changing its direction. In all instances, the object is moving tangent to the circle. Since the direction of the velocity vector is the same as the direction of the motion of the object. The velocity is directed tangent to the circle as well. As object undergoing uniform motion is accelerating due to their change in direction. The direction of the acceleration is inwards.

### Steel is more elastic than rubber - Explain.

Steel is more elastic than rubber - Explain. Elasticity is defined as the attributed property by which a body is able to resist deformation, and recovers its original shape and size when the deforming force is removed. Elasticity is measured by the value of modulus of elasticity and is the ratio of stress and strain. In a steel object, the stress developed for a very small strain under an external force is greater than rubber. Because the intermolecular forces in steel are very strong. So, its modulus of elasticity is greater than that of rubber. So, steel is more elastic than rubber. You may like Why is the Galilean-Newtonian age known as the golden age of science?

### A fever attracted person feels cold but another person feels him hot, why?

A fever-attracted person feels cold but another person feels him hot, why? The body temperature of a fever-affected person is greater compared to that of his surroundings. So, heat flows from his body to the environment and he feels cold. Again, the body temperature of a normal person is less than that of a fever-affected person and that's why he (the normal person) feels the fever-affected person hot.

### The weight of an object is 10N - What does it mean?

The weight of an object is 10N - What does it mean? The force with which the Earth attracts a body towards its center is called the weight of the body. The weight of an object is 10N means that the Earth attracts the body towards its center with a force of 10N. You may like Why is the Galilean-Newtonian age known as the golden age of science?

### Why is unit needed to measure something? Explain.

Why is a unit needed to measure something? Explain. Measurement is related to most of our daily activities. Moreover, we need two things to measure anything. One is a number and the other is a unit. A standard is essential, comparing with which any measurement is done. These standard quantities are called the units of measurement. Without a standard or unit, it is not possible to measure anything easily and accurately. That is why a unit is needed to measure something.

### Explain the cause of flotation of the body?

Explain the cause of flotation of the body? The body is floating being fully immersed in the liquid because the weight of the body equals the buoyancy of the liquid. The situation also reveals that the weight of the body is equal to the weight of the amount of liquid displaced by the body.

### What is Torricelli's vacuum?

What is Torricelli's vacuum? If a one meter long glass tube opened at one end filled with mercury is put into a mercury filled container invertedly and perpendicularly due to air pressure the mercury level comes down. At a certain level it becomes steady which means a portion of tube's upper area becomes vaccum. This vaccum is known as Torricelli's vaccum. You may like Do I need car insurance?

### State Archimedes law

State Archimedes law If a body is immersed in a liquid, the weight of the body is reduced by an amount equal to the displaced liquid.  If an object is partially or completely submerged in a stagnant liquid or gaseous matter then the object seems to have lost a bit of weight. This lost weight is equal to the amount of liquid or gaseous matter abstracted by the object. You may like Do I need car insurance? What is car insurance? How could I get cheaper car insurance?

### What is strain?

What is strain? The relative change in length or shape which is made by applying a force from outside is called strain.  Strain is simply the measure of how much an object is stretched or deformed. Strain occurs when force is applied to an object. Strain deals mostly with the change in length of the object. An example of strain is a pulled muscle. An example of strain is reading a book in the dark, causing pressure on the eyes. You may like Do I need car insurance? What is car insurance? How could I get cheaper car insurance?
