Use table 3 in data booklet to identify the type of radiation (1 pt)

Answers

Answer 1

Answer:

λ = 6.25 × 10⁻¹⁰ m

x-ray

General Formulas and Concepts:

Speed of Light = Wavelength times Frequency

c = λν

Explanation:

Step 1: Define

C = 3.0 × 10⁸ m/s

ν = 4.80 × 10¹⁷ Hz (s⁻¹)

λ = unknown

Step 2: Solve for wavelength

3.0 × 10⁸ m/s = λ(4.80 × 10¹⁷ Hz)

λ = 6.25 × 10⁻¹⁰ m

Step 3: Check

We are given 3 sig figs. Follow sig fig rules.

6.25 has 3 sig figs. No changes necessary.

Step 4: Identify

6.25 × 10⁻¹⁰ m is in the x-ray spectrum according the the Electromagnetic Spectrum

O only unbalanced.
O unbalanced, then balanced.

Answers

Answer:

Unbalanced, then balanced OR only unbalanced

Explanation:

At first, the force is unbalanced. This is what is causing the car to move. Then, the car slows down. If the car were to stop, then it would be unbalanced, then balanced. However, if the car never stops, then it would stay unbalanced the whole time. While it is not a specific answer, I hope this helps!

When Earth is tilted on its axis why does it orbit the sun ?

Answers

Answer:

Explanation:

Some assume our planet's changing distance from the sun causes the change in the seasons. That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun

We have that for the Question,it can be said that How much hydrogen chloride was used in the reaction is

x=74.42

From the question we are told

Magnesium (24.30g) reacts with hydrogen chloride (xg) to produce hydrogen gas(2.04g) and magnesium chloride (96.90g).

How much hydrogen chloride was used in the reaction

How much hydrogen chloride was used in the reaction

Generally the equation for the Reaction is is mathematically given as

Mg+2HCl-----MgCl2+H2

Grams of MgCl2=[tex]\frac{96.9*24.30}{2.04}\\[/tex]
Grams of MgCl2=1154.25g

Therefore

Answers

Answer:

I'm feeling nice today so heres the answer

Explanation:

In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.

Explanation:

Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.

The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.

The other options presented are not correct, because

Respiration is a process that occurs in the mitochondria.

Diffusion is a passive transport process that does not require energy.

Cellular recognition depends on membrane proteins that act as specific receptors.

Answer:the answer is active transport

What is the difference between a physical and chemical change?

Answers

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.

Answer:

Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
