Which best describes a chain reaction associated with a nuclear reaction?!!

Answers

Answer: The statement that describes a chain reaction brought about by a nuclear reaction is "neutrons released during a fission reaction cause other nuclei to split." This is applicable to fission reactions only wherein atoms split and produce neutrons that also cause further atoms to split, thus creating a chain or series of reactions.

Radar detectors use radio waves to measure the speed of moving
vehicles. Radar detectors have a wavelength of 1.8 meters. What is the frequency of waves from a radar detector?

Answers

Answer:

1.7x10^8 Hz

Explanation:

Frequency could be explained as the number of occurrences of a repeating event at a time

Given:

wavelength = 1.8 meters

The frequency f of the waves can be calculated using f = c / λ

Where c (m/s) is the speed of the wave

λ (m) is the wavelength

Speed c= 3*10^8 m/s

Frequency f= 3*10^8 /1.8

Frequency= 1.7x10^8 Hz

Therefore,the frequency of waves from a radar detector is 1.7x10^8 Hz

Round the number 3456.5 to two significant figures.

Answers

Explanation:

35- this is the answer in 2s.f

When rounding a number to two significant figures, we consider the first two most significant digits from the left. In this case, the number is 3456.5. 3456.5 rounded to two significant figures is 3500.

Rounding numbers is a common mathematical process used to simplify or approximate values to a desired level of precision. It involves adjusting a number to a specific decimal place or significant figure.

To round 3456.5 to two significant figures, we look at the first two digits: 34.

The next digit after the second significant digit is 5. Since 5 is greater than or equal to 5, we round up the last significant digit.

Therefore, rounding 3456.5 to two significant figures gives us:

3500

So, 3456.5 rounded to two significant figures is 3500.

If density usually increases with decreasing temperature, why does ice float on liquid water? Explain.

Answers

Answer:

If you continue to cool water past 4 degrees Celsius, its density starts to plummet (you can see this in the graph). At zero degrees, i.e., the temperature at which water turns into ice, the density of water is actually quite low. It turns out that ice has a lower density than water, and any object that has a lower density than the liquid form on which it’s kept (in this case, water) will be able to float!

Explanation:

The ice floats in water because the hydrogen bonds in the ice change to negative, and Ice is, therefore, less dense than water because the density of water actually reduces as the temperature drops.

What are ice and water?

Ice is the form of water. It is the frozen form of water. It is made up of hydrogen and oxygen.

The hydrogen bonds in water change as it cools, holding the negatively charged oxygen atoms apart and preventing the ice from getting much denser.

Water loses density after 4 degrees Celsius of cooling, therefore don't do it  The water's density is actually relatively low at zero degrees, the temperature upon which water transforms into ice.

Thus, as it turns out, ice has a lower density than water, therefore any object will be able to float if its density is lower than that of the liquid state it is kept in.

7. A square chunk of plastic has a length of 5 cm, width of 5 cm and height of 5 cm. It has a mass of 200 g. What is its density?

Answers

Answer:

[tex]d=1.6\ g/cm^3[/tex]

Explanation:

Given that,

The dimension of a square chunk of plastic is 5 cm × 5 cm × 5 cm

Mass, m = 200 g

We need to find its density

Density = mass/volume

It will form a cube. It volume = side³

So,

[tex]d=\dfrac{200\ g}{5^3\ cm^3}\\\\d=1.6\ g/cm^3[/tex]

Hence density is [tex]1.6\ g/cm^3[/tex]

A 20 kg curling stone is sliding in a positive direction at 4 m/s. A second curling stone is sliding at the same speed but in the opposite direction. What is the kinetic energy of the two stones?

Answers

Answer:

The kinetic energy of the two stones is 320 J

Explanation:

Kinetic energy is the energy that a body possesses due to its movement. So it is the capacity or work that allows an object to go from being at rest, or still, to moving at a certain speed.

In other words, the kinetic energy of an object is that which is produced due to its motion and depends on its mass and velocity as follows:

[tex]Ec=\frac{1}{2} *m*v^{2}[/tex]

where the kinetic energy Ec is measured in joules (J), the mass m is measured in kilograms (kg) and the velocity v in meters/second (m/s).

In this case you know that a 20 kg curling stone is sliding in a positive direction at 4 m/s. So:

m= 20 kgv= 4 m/s

Replacing you have:

[tex]Ec_{1} =\frac{1}{2} *20 kg*(4\frac{m}{s}) ^{2}[/tex]

Ec₁= 160 J

A second curling stone slides at the same speed but in the opposite direction. So:

m= 20 kgv= - 4 m/s

Replacing you have:

[tex]Ec_{2} =\frac{1}{2} *20 kg*(-4\frac{m}{s}) ^{2}[/tex]

Ec₂= 160 J

The kinetic energy of the two stones is calculated as:

Ec= Ec₁ + Ec₂

Ec= 160 J + 160 J

Ec= 320 J

The kinetic energy of the two stones is 320 J

Calculate the mass of water if the densityis 1.02 g/mL and the volume is 62 ml. M = (D(V)
.016 mL
60.78 mL
63.24 mL
73.24 mL

Answers

Answer:

The answer is

63.24 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 62 mL

density = 1.02 g/mL

The mass is

mass = 1.02 × 62

We have the final answer as

63.24 g

ANSWER PLEASE ..Which property of an element would be MOST helpful in determining its column in
the periodic table?

Answers

Im not sure but I recommend taking a look at the periodic table

The column number of an element in the periodic table is generally determined on the basis of the number of valence electrons. The elements in the same column have similar chemical properties.

What are valence electrons?

The electrons present in the outermost shell of an atom which take part in chemical reactions are called the valence electrons. These electrons are responsible for the interaction between the atoms and the formation of chemical bonds.

The valence electrons of an atom also gives us an idea about the chemical properties of elements like valency, the number of unpaired electrons present, etc. The column number of an element is mainly determined on the basis of number of valence electrons.

The elements are placed in vertical columns in the periodic table. There are 2 electrons in the outermost shell of Alkaline earth metals. So they belong to second column.

Thus it is the valence electron which determines the column number.

The place is equipped with sophisticated machines, test samples, hazardous chemicals, instruments  etc.

The university or college lab, there is a incharge of the lab called as the lab instructor who is responsible for all the belongings of the lab and the safety of the experimenter or the students.

After performing some experiments or testing with some chemicals, the last and the most important thing we need to do is to wash our hand with soap or hand wash. it is very important because we touch many test samples and hazardous chemical which might go inside our mouth or eyes accidentally, which might be harmful to us.

So, it is important to wash our hand at last before leaving the lab.
