What is the volume of the table tennis ball?
cm3
The volume of the water in the graduated cylinder rose
as some of the water was displaced by the table tennis
ball. Find the volume of the ball using the formula
Vb = Vf-Vi
where Vb is the volume of the ball, Vf is the final volume
of the water, and Vi is the initial volume of the water.
Record the volume of the ball in Table A of your Student
Guide.

Answers

Answer 1

The volume of the ball is the same as the volume of fluid that it displaces.

Even though the question is incomplete but i will try to help you the much i can. We have to recall that the volume occupied by the tennis ball is equal to the volume of the water displaced and this offers a convenient way of measuring the volume of solids.

The volume of the tennis ball is obtained by accurately measuring he volume of the water before putting in the tennis ball. The volume of the ball is the same as the volume of fluid that it displaces which is Vb = Vf-Vi

A container has a mass of 3.5 grams and a volume of 2.3 cm. What is the density of the container?

Answers

Answer:

1.5217391304348 gram/cubic centimeter is the density

3.5 gram/2.3 cubic centimeter

The density of the container is 1.52gms/cm.

What is density?

Three of a fundamental properties of certain objects are basically mass, volume, and density.

Mass characterizes how heavy the material is, volume defines its size, and density is referred to as mass divided by volume. Despite the fact that mass and volume are everyday concepts.

One of an object's most important and easily measured physical properties is its density.

Densities are commonly used to identify pure substances as well as to characterize and estimate the composition of various types of mixtures.

Density is an important concept because it determines which substances will float and which will sink.

Substances float in general if their density is less than the density of the liquid in which they are placed.

Given that,

Mass = 3.5gm.

Volume = 2.3 cm.

Density = ?

We know that,

Density = mass/volume.

Density = 3.5/2.3

Density = 1.52gms/cm.

Thus, the density for the given data is 1.52gms/cm.

How many dimes could you trade for 360 pesos? $1 = 1500 pesos.
O 1.5 dimes
O 5.4 dimes
O 540 dimes
O 2.4 dimes

Answers

Answer:

The correct option is (d).

Explanation:

It is given that,

1$ = 1500 pesos

We need to convert 360 pesos into dimes

We can convert 360 pesos to dollars as follows:

[tex]360\ \text{pesos}=\$\dfrac{1}{1500}\times 360\\\\=$0.24[/tex]

360 pesos is equal to $0.24

Also, 1 dollar = 10 dimes

We can covert 0.24 dollar to dimes as follows :

0.24 dollar = 10 × 0.24 dimes

0.24 dollar = 2.4 dimes

or

360 pesos = 2.4 dimes

A plasma that has particles that never collide frequently enough to exchange kinetic energy and never reach a temperature equal to the surroundings is categorized as a thermal plasma. ionized plasma. low density plasma. nonthermal plasma.

Answers

Answer:

For comprehension, the question is written properly with options attached below:

plasma that has particles that never collide frequently enough to exchange kinetic energy and never reach a temperature equal to the surroundings is categorized as:

A. a thermal plasma.

B. ionized plasma.

C. low density plasma

D. nonthermal plasma.

The correct answer to the question above is "Option D (nonthermal plasma.)"

Explanation:

Plasma, for example radiant sun are state of matter made up of atoms where the ions move freely, there are composed of photons and free electrons but the positive and negative ions are equal creating a swirling gas of positive ions and negative electron and they are also good conductors of electricity as their charged particles move.

Unlike thermal plasmas that ensure their temperature is equal to their surroundings, non-thermal plasma, is not in equilibrium with its surrounding., in other words, non-thermal plasma never reaches temperature that is equal to their surroundings. They can be formed by electrifying electromagnetic waves.

A plasma with particles that never collide frequently to exchange kinetic energy is : ( D ) Nonthermal plasma

A plasma is a body of matter made up photons and  freely moving ions contained its atoms the free moving ions are both positive and negative ions which are equal to each other.

A Thermal plasma collide frequently enough to reach a temperature that is equal to the temperature of the surroundings while Nonthermal plasma does not collide enough and does not reach an equilibrium temperature with its surrounding.

Hence we can conclude that A plasma with particles that never collide to exchange kinetic energy is A Nonthermal plasma.

A gold-colored ring has a mass of 17.5 grams and a volume of 0.82 mL. What is the density of this ring?

Answers

Answer:

21 g/mL

Explanation:

To solve this problem, first look at the density equation, which is D=M/V, which D stands for density, M stands for mass, and V stands for volume. When you substitute in the variables, you get D=17.5/.82, which is equivalent to 21.34. However, since we need to pay attention to the sig fig rules for multiplying, we need to have the same amount of sig figs as the value with the least amount of sig figs, which is the number .82. .82 has two sig figs, so you round down. Your answer will be 21 g/mL.

how did Bohr change Rutherford's model​

Answers

To remedy the stability problem, Bohr modified the Rutherford model by requiring that the electrons move in orbits of fixed size and energy. The energy of an electron depends on the size of the orbit and is lower for smaller orbits. Radiation can occur only when the electron jumps from one orbit to another.

Explanation:

To solve that deadlock problem, in 1913 Bo kept Rizopho's model of planetary atom and combined with Plang quantum theory, he produced a hydrogen atom model with the following three determinations: - In atoms, The clectron cannot orbit any other, but only rotates with a certain number of orbits. Each "allowed" orbit is equivalent to a certain energy. - When rotating in "allowed" orbits, electrons do not lose energy, meaning they do not emit radiation, but emit radiation only when the electron jumps from an orbit with the high energy level in the orbit corresponding to the the low energy and the household energy of radiation are equal to the difference of the two energy levels. - - When rotating in those "allowed" orbits, the electron has a momentum moment that is an integer times of h / (2π).

Maggie loves fresh brownies, and her grandma told her if she places a piece of bread in the storage container with the brownies, the brownies will stay fresh and moist longer. Maggie decides to test this idea. She bakes a batch of Betty Crocker brownies. She places 6 brownies in 6 individual tupperware containers. Each brownie is the same size and placed in the same location. She adds a piece of bread to three of the brownie containers, and leaves the other three alone. Each day for three weeks she measures the moistness of the brownies and records her results. What is the independent variable? What is the dependant variable? What are the constants? Hypothesis? What are the control groups? What is the experimental group?

Answers

Answer:

Independent variable - Piece of bread

Dependant variable - Moistness of brownie

Constants- Same size and location of brownie

Hypothesis - IF a piece of bread is added to a brownie container, THEN the brownie will be moister

Control groups- The set of brownie containers she adds no piece of bread to

Experimental group- The set of brownie containers she adds a piece of bread to

Explanation:

The hypothesis in an experiment is a testable explanation to a given problem, which is whether a piece of bread can make brownie moist in this question. Hence, a possible hypothesis will be: IF a piece of bread is added to a brownie container, THEN the brownie will be moister

Independent variable is the variable that the experimenter changes or manipulates in the experiment. In this case, the independent variable is the PIECE OF BREAD added to the brownie.

The dependent variable is the variable that is being measured in an experiment. The dependent variable in this case is the MOISTNESS of the brownie

Constants are variables that the experimenter keeps unchanged for all the groups throughout the experiment. In this case, the constants are SAME SIZE AND LOCATION OF BROWNIE.

Control group is the group that does not receive the experimental treatment or independent variable while the experimental group is the group that receives the experimental treatment. The control group in this experiment is: The set of brownie containers she adds no piece of bread to, while the experimental group is the: The set of brownie containers she adds a piece of bread to

What are 2 examples of what happens when scientist do not have a standard system of measurement of the scientific community?

Answers

Answer:

Explanation:

The standard system of measurement is what is popularly referred to as SI unit (or international system of units). For example, the SI unit for length is basically in meters (m), which is convertible to millimeter (mm), centimeter (cm) or even kilometer (km).

If there is no standard system of measurement,

1) Scientists will not be able to compare data as every scientist will use a unit that suits him/herself which might make data incomparable as some units might be difficult to convert to other units or there conversion methods might even be debatable.

2) There might be a general lack of understanding of the research work done by a scientist/scientists in the scientific community. This is because the standard system of measurement affords scientists to communicate properly with the same or convertible units and based on 1. above, if scientists use any unit that isn't agreed upon, different/unknown/debatable units might make understanding of research works incomprehensible.
