Mr. Chang's class participated in a science experiment where they placed three substances outside in the sunlight to determine which substance would increase in temperature more quickly. How would the motion of the particles of each substance be described if they are allowed to sit in the sun for a duration of 10 minutes?.

Answers

Answer 1

In order to find out which substance would raise in temperature most quickly, Mr. Chang's class conducted a scientific experiment outside in the sunlight using three different substances.

If particles of each substance were permitted to sit in the sun for 10 minutes, how would their motion be described? B. Physical alterations are non-chemical changes that are made to an item or substance. They alter an object's physical characteristics, such as its size, color, texture, volume, or density. To find out more about the science underlying the treat or to find some more at-home experiments, see the resources listed below.

A baseball is thrown with a speed of 36 meters per second (m/s). What is the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand and cross the plate? A-72 B-18 C-41 D-31 Help me out please

Answers

Answer:

d = 18 m

Explanation:

Given that,

The speed of a baseball, v = 36 m/s

We need to find the distance from the mound to home plate if the ball takes 0.5 seconds to leave the pitcher's hand and cross the plate.

Let the distance be d. We can find it using the formula,

Speed = distance/time

or

[tex]d=vt\\\\d=36\times 0.5\\\\d=18\ m[/tex]

So, the required distance is equal to 18 m.

Plan an experiment to measure the ideal mechanical advantage of a three-hole punch. (a) What materials would you need? (b) What procedure would you use?

Answers

Answer:

A) Three hole punch and either a layered plastic or paper

B) Identify the lengths involved  ,

  Length of input arm / length of output arm = L1/ L2

Explanation:

a) Materials involved includes :

Three hole punch and either a layered plastic or paper

Identify the forces acting on the three-hole punch which are Input and output forces

Identify the points where they act

B) procedures involved

The mechanical advantage = output force / input force

step one:  Identify the lengths involved

assuming no friction or relatively small friction \

mechanical advantage can be calculated as : Length of input arm / length of output arm = L1/ L2

A 100 L ball is blown up inside at 200K. It is then taken outside in the hot sun, and the volume increases to 150 L. What is the new temperature?​

Answers

Answer:

Temperature, T2 = 300 Kelvin

Explanation:

Given the following data;

Initial volume = 100 Liters

Initial temperature = 200 Kelvin

Final volume = 150 Liters

To find the final temperature T2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

[tex] \frac {V}{T} = K[/tex]

[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]

Making T2 as the subject formula, we have;

[tex] T_{2}= \frac{V_{2}}{V_{1}} * T_{1}[/tex]

Substituting into the formula, we have;

[tex] T_{2}= \frac{150}{100} * 200[/tex]

[tex] T_{2}= 1.5 * 200 [/tex]

Temperature, T2 = 300 Kelvin

Calculate the force of an object shot in the air with a mass of 2 kg and an acceleration of 9.81 m/s2.

Answers

Answer:

Force = 19.62 Newton

Explanation:

Given the following data;

Mass = 2kg

Acceleration = 9.81 m/s²

To find the force;

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

Substituting into the formula, we have;

Force = 2 * 9.81

Force = 19.62 Newton

The equation below shows a general equation for a reaction, and the amounts of the substance are written underneath.

AB + CD → AC + BD
(15 g) (?) (?) (10 g)

The total mass of the products is 50g. Which best completes the other two amounts?

The amount of CD is 40 g, and the amount of AC is 35 g.
The amount of CD is 35 g, and the amount of AC is 40 g.
The amount of CD and AC would be the same.
The amount of CD and AC is undetermined.

Answers

Explanation:

The amount of CD is 35 g, and the amount of AC is 40 g.

Explanation:

AB + CD \rightarrow AC + BDAB+CD→AC+BD

The law of conservation of mass states that in any chemical reaction, the total mass of the reactants must be equal to the total mass of the products.

In this reaction, we know the mass of one reactant (AB, 15 g) and the mass of one product (BD, 10 g). In order to have the same total mass on the left side and on the right side of the equation, the mass of AC must be 5 g more than the mass of CD. We see that the only choice that satisfies this condition is:

The amount of CD is 35 g, and the amount of AC is 40 g.

In fact, if we assume these masses are correct, we have:

- on the reactant side: m(AB)+m(CD)= 15g + 35g = 50g

- on the product side: m(AC)+m(BD)= 40g + 10g = 50g

so, we have the same mass on both sides of the equation, and the law of conservation of mass is satisfied.

Answer:

B is  the answer on edge

Explanation:

B: The amount of CD is 35 g, and the amount of AC is 40 g.

Your little cousin loves ice cream bars. You buy him one and he starts to lick it. As you sit down on a park bench, he drops
the bar on the seat of the bench. You pick up the bar to throw it away, but he starts to cry, so you shrug and give it back to
him. Will he definitely get sick?

Answers

Answer:

nop

Explanation:

It is not certain whether the child will get sick from eating the ice cream bar that was dropped on the bench.

What is contamination?

Contamination refers to the presence or introduction of harmful substances or organisms into a material, environment, or food source.

There is a possibility that the ice cream bar could have picked up bacteria or other contaminants from the bench that could make the child sick. However, the risk of illness depends on a number of factors, including the cleanliness of the bench, the length of time the ice cream was in contact with the bench, and the overall health of the child's immune system.

To reduce the risk of illness, it is important to wash hands and surfaces frequently, especially when handling food. If possible, it is best to discard food that has come into contact with potentially contaminated surfaces to prevent the spread of illness. However, if the child has already eaten the ice cream bar and does become sick, it is important to monitor their symptoms and seek medical attention if necessary.
