Yes the heavier then in most cases the farther. Something with no mass wont roll very far.

Yes, it depends on the size of the ball and the weight. If it's heavy and big then it'll affect how far it rolls, if it's small and has no weight then it won't really move as much

7 Which physical characteristic of a solution may
Nuetrik [128]

Answer:

2= its color

Explanation:

Transition elements are present in the middle of periodic table. These are d-block elements.

These are 38 elements.

All transition elements have partially filled d orbitals.

They showed color in compound because of d-d transition.

During the d-d transition electron absorbed the energy and emit the reminder energy. The emission is usually in the form of color light.

The color of ion is complementary to the absorbed color.

The transition elements are used as a catalyst in industries such as polymer, petroleum industries.

They are ductile, conduct heat and electricity.

The emission spectrum of cesium contains two lines whose frequencies are (a)
Lady bird [3.3K]

The lines are violet and blue respectively.

<h3>What is the energy?</h3>

We know that the energy of the photon could be obtained by the use of the equation;

E = hf

E = energy

h = Plank's constant

f = frequency

For the first line;

E = 6.6 * 10^-34 Js * 3.45 x 10^14 Hz = 2.3 * 10^-19 J

Given that;

E = hc/λ

λ = hc/E

λ = 6.6 * 10^-34 * 3 * 10^8/2.3 * 10^-19

λ = 8.61 * 10^-7 m or 861 nm

The color is violet

For the second line;

E = 6.6 * 10^-34 Js * 6.53 xx 10^14 Hz

E = 4.3 * 10^-19 J

E = hc/λ

λ = hc/E

λ =  6.6 * 10^-34 * 3 * 10^8/4.3 * 10^-19

λ = 4.60 * 10^- 7 m or 460 nm

The color is blue

Nonrenewable energy sources _____.
shusha [124]

Non-renewable energy sources CAN EVENTUALLY BE USED UP.

Non renewable energy sources refer to those energy sources that can not be replenished. Once they are used up, new one can not be formed or produced, this is because they can only be formed by natural processes and these processes take millions of years to occur. Examples of non renewable energy sources are: coal, natural gas and oil. All the fuels obtained from fossils are non renewable in nature.
