Why is the use of the inquiry process (or scientific method) a practical way to approach science?

1. The inquiry process is a practical way to approach science because the inquiry process begins by asking questions and moving on from there.  

2. In science it is important to investigate phenomena or certain subjects by posing questions that you would like to answer through the scientific method.

3.  Therefore, the inquiry method is connected because to inquire on a subject requires raising questions which is an essential step in scientific discovery.

Why are scientific theories modified, but seldom discarded?

1.  If a theory cannot explain new evidence or observations then the theory is revised or even thrown

out, but if the theory still explains a wide range of observations and evidence then it is revised

rather than discarded.

2.  it will still hold some value as above as you learn more you tweak your hypothesis to fit the ever expanding amount of info and data you collect and assimilate

3.  The only way they ever go away is if people stop working on them.

How has science and technology influenced everyday life?

1.  computers

2.  health care

3. bikes

None of these would exist today without science or technology

Answer: It would have a high pitch.

Explanation: since the whistle has a high frequency, I can infer that it will have a high pitch.

Answer:

it would have a high pitch

Explanation:

like if u take a hearing test the sounds are usually high pitch

Answer:

Thermal energy transfers occur in three ways: through conduction, convection, and radiation. When thermal energy is transferred between neighboring molecules that are in contact with one another, this is called conduction.

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s

kinetic energy is given as

2) when speed is 3 m/s

kinetic energy is given as

3) when speed is 4 m/s

kinetic energy is given as

4) when speed is 5 m/s

kinetic energy is given as

5) when speed is 6 m/s

kinetic energy is given as

I believe this is right-

Beetles are insects that belong to the superorder Endopterygota's Coleoptera order (/koliptr/). They can be distinguished from most other insects by the fact that their front pair of wings have solidified into wing-cases, or elytra.

Beetles are the most common type of insect.  Beetles are everywhere.  But beetles can be confused with other kinds of insects, especially some true bugs. Beetles differ from all other winged insects by having the first pair of wings hardened and thickened.

Some real bugs (Order Hemiptera) have wings that resemble beetles in some ways. However, true bug wings are only partially thickened and stiffened. True insect wings are translucent on the outside.  The mouth parts of the two groups can also be used to distinguish them.

Because the bugs with body color A are able to blend into the habitat/trees better, which makes it harder for the birds to see.

There is one further difficulty with identifying beetles. Beetles go through a significantly different-looking immature (or larval) stage before emerging as winged adults.

Hello there!

How is density different from weight and mass you say? It's simple!

1. Unlike weight, density is composed of mass and volume.

2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.

Hope this helps :) if so, can I get Brainliest?

c. The atom becomes positively charged

if the electrons are removed it means theres no longer a negative charge to balance the positive charge of the protons in the atom

Answer:

The Ozone layer

Explanation:

Ozone in the atmosphere can absorb ultraviolet light, which stops the light from reaching Earth’s surface, so people absorb less of it. Australia has less ozone than other places, like Brazil, and this is why Australia gets more ultraviolet light.

Zinc + hydrogen chloride= zinc chloride+ hydrogen

Answer:

No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
