never [62]3 years ago
8 0

Answer:

A general guideline to determine if oxide is acidic, basic, or amphoteric is to use the periodic table. Typically, metals such as Ba form basic oxides (BaO), while nonmetals such as S form acidic oxides (SO3).

1/2 * m * v ^ 2 = mgh
viktelen [127]

C. the square root of 2gh

Explanation:

The square root of 2gh is equivalent to Torricelli's law in the equation.

  given expression:

         \frac{1}{2} m v² = mgh

 to find v, we make it the subject of the expression:

    *multiply both sides of the equation by 2:

             

                     2 x( \frac{1}{2} m v² )= 2 (mgh)

                                      mv²  = 2mgh

    *cancel the mass, m appearing on both sides:

                                    v²  = 2gh

  * find the square root of both side

                                     v = √2gh

Metallic pan is provided with a wooden plastic handle give reason​
AlladinOne [14]

The metallic pan iis most likely going to be used on a stove.

The stove is heating something, and the conductive metallic pan will, well, conduct that heat throughout the entire body of the pan. Doing this will spread the heat to the handle, burning your hands.

Both wood and plastic are insulators, and they do not conduct heat or electricity. They will insulate your hands and protect them from the heat.

Dalton's Atomic Model
olga_2 [115]

Answer:

A theory of chemical combination, first stated by John Dalton in 1803. It involves the following postulates: (1) Elements consist of indivisible small particles (atoms). (2) All atoms of the same element are identical; different elements have different types of atom. (3) Atoms can neither be created nor destroyed. Based on all his observations, Dalton proposed his model of an atom. It is often referred to as the billiard ball model. He defined an atom to be a ball-like structure, as the concepts of atomic nucleus and electrons were unknown at the time.

John Dalton developed a crude method for measuring the masses of the elements in a compound. His law of multiple proportions states that when two elements form more than one compound, masses of one element that combine with a fixed mass of the other are in a ratio of small whole numbers.
