What is experiment ?

An experiment is a technique used to confirm or deny a hypothesis, as well as assess the possibility or effectiveness of something that has never been done before. Experiments show what happens when a certain component is modified, which sheds light on cause-and-effect relationships. The purpose and scope of experiments vary widely, but they always rely on a repeatable process and a rational examination of the outcomes. Natural experimental experiments are also a thing.

While a child may conduct simple experiments to better understand how objects fall to the ground, scientific teams may spend years conducting thorough research to increase their understanding of a phenomenon.

This experiment shows enthalpy is positive, heat is absorbed in this experiment. this breaks the atoms and it needed the energy.

A 1800 kg car moving south at 17.5 m/s collide with a 2800 kg car moving north. The cars stick together and move as a unit after the collision at a velocity of 5.22 m/s to the north. Find the velocity of the 2800 kg car before the collision

Answers

Answer:

   v₀₂ = -2.67 m / s

Explanation:

Let's use the conservation of the moment, for this we define a system formed by the two cars.

Consider the north direction as positive and the subscript 1 will be used for car 1 and the subscript 2 for the second car

Initial instant. Before the crash

          p₀ = -m₁ v₀₁ + m₂ v₀₂

Final moment. Right after the crash

          p_f = (m₁ + m₂) v

           p₀ = p_f

           -m₁ [tex]v_{o1}[/tex] + m₂ v_{o2} = (m₁ + m2) v_{f}

         v₀₂ = [tex]\frac{(m_1 +m_2) v }{m_2}[/tex]+  [tex]\frac{m_1 v_{o1} }{m_{1} }[/tex]

 

let's calculate

          v₀₂ = [tex]\frac{(1800 +2800) 5.22 + 1800 (-17.5)}{2800}[/tex]

          v₀₂ = -2.67 m / s

the negative sign indicates that the carriage moves in the opposite direction of the temperies

The outside diameter of your teacher's rear bicycle tire is 16 inches. How far will he travel if the rear wheel makes 1200 revolutions on the road?

Answers

Answer:

241,274.32 inches

Explanation:

How far will he travel if the rear wheel makes 1200 revolutions on the road?

Since the rear wheel makes one revolution in the distance of a circumference of a circle, C with diameter, d = 16 inches

C = πd²/4

So, the distance, travelled in 1200 revolutions is D = 1200 × C = 1200πd²/4

Substituting d = 16 into D, we have

D = 1200πd²/4

D = 1200π(16)²/4

D = 76800π

D = 241,274.32 inches

245 ml
345 ml
123 ml
250.mL

Answers

Answer:

245 ml

Explanation:

rfdhccchhhgugvhh

The original volume of the sample of hydrogen is 250 mL. The correct option is the fourth option 250mL

From the question,

We are to determine the original volume of the hydrogen.

To do this,

We will use the Boyle's law formula

Boyle's law states that "the volume of a fixed mass of gas is inversely proportional to its pressure, provided that the temperature remains constant."

From Boyle's law we have that

P₁V₁ = P₂V₂

Where P₁ is the initial pressure

V₁ in the initial volume

P₂ is the final pressure

and V₂ is the final volume

From the question,

P₁ = 1.5 atm

P₂ = 0.50 atm

V₂ = 750 mL

Put the above parameters into the Boyle's law equation

P₁V₁ = P₂V₂

Then, we get

1.5 × V₁ = 0.50 × 750

1.5 × V₁ = 375

∴ V₁ = 375 ÷ 1.5

V₁ = 250 mL

Hence, the original volume of the sample of hydrogen is 250 mL. The correct option is the fourth option 250mL

Resistor 1 has a resistance of 10 N and
carries a current of 3 A. Resistor 2 has a resistance of
5 and carries a current of 10 A. Which resistor has
the greater potential difference?

Answers

Answer:

Resistance 2.

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage. I represents current measured in amperes. R represents resistance measured in ohms.

Note: Voltage is the same as potential difference.

Given the following data;

Resistance 1  = 10 Ohms

Current 1 = 3 Amperes

Potential difference 1 = current * resistance

Potential difference 1 = 3 * 10

Potential difference 1 = 30 V

To find the potential difference in 2;

Resistance 2 = 5 Ohms

Current 2 = 10 Amperes

Potential difference 2 = 10 * 5

Potential difference 2 = 50 V

Therefore, Resistance 2 has greater potential difference.

5. What do you think? At a baseball game, when you are far from the batter, you might see the batter hit the ball before you hear the sound of the hit. Why do you think this
happens?

Answers

Answer:

The speed of sound in air is lower compared to in solids and liquids.

Explanation:

Sound is a wave that can be generated by a vibrating body. Its speed through different media differs due to the nature of the media.

Since the molecules of solids are closely packed, sound can be easily transferred from one molecule to another at a faster rate. Thus, the high speed of sound in solids.

In liquids, the molecules are not as closely packed as solids. So that  the speed of sound though liquids is lower compared to that of solids. Gases has its molecules farther apart, thus making the speed of sound through it the lowest compared to solids and liquids.

Therefore the sound of the batter hitting the ball is heard latter, due to its lower speed through the air.

Exercise 1 Read the passage. Based on what you already know, underline the verbs.The Marshmallow ExperimentImagine that you are seven years old. You are participating in an experiment. A researcher greets you and shows you into a small room. In the room there is a marshmallow. The marshmallow is for you, but here is the interesting part: The researcher tells you that he is going to leave you alone in the room for a while. You can eat the marshmallow right away, or you can wait until he gets back. If you wait until he gets back, you will get a second marshmallow.What do you do? Do you eat the marshmallow right away?An experiment like this, known informally as the marshmallow experiment, was conducted decades ago at Stanford University. It turned out that some children ate the marshmallow right away, while others were able to wait. In other words, some sought instant self-gratification, and some delayed it.Years later, the researchers followed up on the participants. They found that the children who delayed self-gratification were in general more successful than those who ate the marshmallow right away. By a variety of measures, including SAT scores, they appeared to be more competent.Common sense tells us that the ability to delay self-gratification is a mark of maturity. The marshmallow experiment provides evidence that it may also correlate with success in life.Notes:- Many of these verb phrases consist of an auxiliary verb and a main verb. So, for example, are participating and do...eat are considered verb phrases.- is going to leave: If we consder is going to a kind of auxiliary verb, then this is a verb phrase, just like will leave.- known as...: If you underlined known, thats fine. It is a verb. It is a nonfinite verb, unlike the other underlined verbs and verb phrases. (See Chapter 4.) Exercise 2 Underline the complete subjects in the sentences below, and double- underline the verbs that go with them. Identifying the subject means identifying the main word of the subject and the parts that modify it. (In the first sentence, the main word is in boldface.) When you underline the verb, include both auxiliary verbs and main verbs (as in the first sentence, with was...used).In the 1960s and 70s, the term generation gap was often used to refer to the differences between young people in the U.S. and their parents generation.

Since then, conflicts between generations have diminished in many ways. Child-rearing experts in the late 20th century encouraged parents to be like friends to their children.
