Answer:

cannot be used to produce energy in reactors.  

Explanation:

Currently, there is no reactor that can allow the use of nuclear fusion, although nuclear plants use nuclear fission reactors.

Nuclear fusion happens when thousands of atoms collide with each other when they are in the midst of extreme conditions of literature and pressure. This collision causes the atoms to fuse, creating another element. The process releases amounts of light and heat, promoting a high release of energy. This whole process occurs without the release of CO2 into the atmosphere, without the release of toxic waste and without the risk of explosions, which makes nuclear plants have a strong interest in building a reactor to use this type of energy. For this reason, scientists from different countries have collaborated with each other on a project called Iter, which seeks to build a reactor and achieve the first reaction in 2025.

Answer:

B

Explanation:

The attraction is stronger when the magnet is closer so moving it away would decrease the strength.

Answer:

At point A, the beginning of observations, the substance exists in a solid state. Material in this phase has _____fixed____________ volume and ______________fixed___ shape. With each passing minute, ______________heat___ is added to the substance. This causes the molecules of the substance to _____collide____________ more rapidly which we detect by a ______temperature__________ rise in the substance. At point B, the temperature of the substance is __________°C. The solid begins to ______melt__________. At point C, the substance is completely ______liquid_________ or in a _______________ state. Material in this phase has _______fixed__________ volume and ______no definite______ shape. The energy put to the substance between minutes 5 and 9 was used to convert the substance from a ________solid__________ to a __________liquid_______. This heat energy is called the latent heat of fusion. (An interesting fact.)

The answer is true!

Explanation:

A scientific law is the description of an observed phenomenon. The explanation of a phenomenon is called a scientific theory.

Answer:

+30

Explanation:

The nucleus holds both protons and neutrons. Since a neutron is neutral there is no charge. Protons are a positive charge. so the atoms nucleus is +30.

The charge on an atom's nucleus is the same as the number of protons in the nucleus. The charge on the nucleus of the atom is +30.

The nucleus houses positive particles called protons. Each proton carries a charge of +1.

The magnitude of charge of the nucleus is the same as the number of protons in the nucleus.

Since there are 30 protons, the magnitude of  charge of the nucleus is expected to be + 30.

There are 5 stages of breast cancer: stage 0 (zero), which is non-invasive ductal carcinoma in situ (DCIS), and stages I through IV (1 through 4), which are used for invasive breast cancer. The stage provides a common way of describing the cancer, so doctors can work together to plan the best treatments.

Answer:

3.7 mL

Explanation:

Step 1: Given data

Volume of water before the chalk is added: 8.7 mL

Volume of water after the chalk is added: 12.4 mL

Volume of the chalk: ?

Step 2: Calculate the volume of the chalk

The volume of the chalk is equal to the volume of water after the chalk is added minus the volume of water before the chalk is added.

V = 12.4 mL - 8.7 mL = 3.7 mL

Answer:

6.67 %

Explanation:

Given that,

Measured height of a small lamp, l = 32 cm

Actual height, l' = 30 cm

We need to find the percent error of the student's measurement. Percent error is given by :

[tex]\%=\dfrac{|l-l'|}{l'}\times 100[/tex]

Putting all the values, we get :

[tex]\%=\dfrac{|32-30|}{30}\times 100\\\\\%=\dfrac{2}{30}\times 100\\\\\%=6.67\%[/tex]

So, the percent error of the student's measurement is 6.67 %.

strontium

Explanation:

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.

In general, the size of an atom will decrease as you move from left to the right of a certain period.

Order of increasing atomic radius:

O < H < S < I < Sr

The atomic radius measures the separation between an atom's nucleus and its farthest electrons.

Answer:

C.. one enegry level..

Answer:

Energy sources do not have 100% efficiency because the processes of energy conversion to usable forms involves energy losses.

Some have lower efficiencies due to; energy losses in form of heat during conversion, poor technology applied during conversion of energy and lack of desire equipment to use in the energy conversion system.

Explanation:

The desired form of energy for use is derived from conversion of energy from the source using an energy converter into another form which is usable. The efficiency of the energy converter is calculated as;

л = output energy/input energy

The efficiency of energy is limited to the cost of equipment required for conversion from energy source by the energy converter to a form which is usable. Additionally, because energy sources are scarce, the technology to use in energy  conversion is a factor affecting energy efficiency in that high efficiency will require advanced technology with better equipment leading higher costs of that energy form. when heat losses are involved during energy conversion, efficiency lowers, thus its better if such losses are used as energy input in another system.

Answer: With the portion of hydrogen, all atoms have three parts. The parts of an atom are protons, electrons, and neutrons. A proton is accurately charged and is located in the center or nucleus of the atom. Electrons are negatively charged and are located in rings or orbits spinning around the nucleus.

Explanation: I hope this was helpful.

Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density. Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density.
