Answer:

The planet Neptune inspired the name of the element Neptunium.

Dmitri Mendeleev, who created one of the earliest periodic tables, was the source of the name of the element Mendelevium.

Four different objects are placed on a number line at 0. The chart describes the motion of each object. Using the information in

mote1985 [20]

The chart with the information to answer this question may be found in other Brainly's link, so I attach it now.

Answer:

Explanation:

To facilitate the accompaniment of the reasoning, I copy the data here:

Object Motion

X 3 units left, 3 units right

Y 6 units right, 18 units right

W 8 units left, 24 units right

Z 16 units right, 8 units left

The <em>distance</em> is the scalar magnitude that indicates the total length of the path traveled.

The <em>displacement</em> is the vector that indicates how far the end point and the initial point are.

In order to calculate the distance, the displacement and the ratio r = distance/displacement, to check which object has a distance that is three times as great as its displacement, i.e. r = 3, we use this new chart:

Object Motion Distance Displacement ratio

X 3 units left, 3 units right 3 + 3 = 6 3 - 3 = 0 ∞

Y 6 units right, 18 units right 6 + 18 = 24 6 + 18 = 24 1

W 8 units left, 24 units right 8 + 24 = 32 -8 + 24 = 16 2

Z 16 units right, 8 units left 16 + 8 = 24 16 - 8 = 8 3

The ratios were calculated dividing the distance by the displacement: distance / displacement.

For the object Z, that was 24 / 8 = 3. Thus, the object that has a distance that is three times as great as its displacement is the object Z.

Which best describes the importance of the microscope to the development of cell theory? Microscopes color different parts of ce

aliya0001 [1]

Cells are too small to see with the naked eye.

It's pretty straight forward, use the cross-out method.

1) Microscopes MAGNIFY images, they don't color the cells. In fact, scientists have to use these chemicals to "stain" or color the cells to see them more easily through microscopes.

2) If the lenses of a microscope reduced the image of an organism to the size of a cell, you'd be seeing a very tiny human through your microscope, instead of actual cells.

3) Microscopes don't "trap" anything. In fact, scientists use plates or slides under microscopes to contain what they're studying.

If the rate law for a reaction A → P is rate = 3.37x10-3 M^-1 min-1 [A]^2 and the initial concentration of a is 0.122 M, calcula

DedPeter [7]

Rate = 3.37x10-3 M^-1 min-1 [A]^2 and the initial concentration of a is 0.122M.

A rate law indicates the rate of a chemical response depends on reactant concentration. For a response inclusive of the price regulation commonly has the form rate = ok[A]ⁿ, in which okay is a proportionality constant known as the fee regular and n is the order.

The charge of a chemical response is, perhaps, its maximum crucial asset because it dictates whether or not a reaction can arise all throughout an entire life. knowing the charge regulation, an expression concerning the price to the concentrations of reactants can assist a chemist to modify the response conditions to get an extra suitable rate.

half-life is the time taken for the radioactivity of a substance to fall to 1/2 its authentic cost whereas implies existence is the common life of all the nuclei of a particular risky atomic species.
