Explanation:

1) region outside the nucleus divided into energy levels  : electron cloud

Energy levels are specific spherical orbitals around the nucleus. The region of maximum probability of where an electron is located is called an electron cloud or orbital.

2) located in the outermost energy level, determines how element will react chemically with other elements: valence electrons

Valence electrons are electrons in the outermost energy shell of an atom. They determine whether an atom will react chemically with other elements of not.

3) outermost energy level : valence shell

The valence shell where the outermost electrons are located is the outermost energy level.

4) atoms that have the same number of protons but different numbers of neutrons : isotopes

Isotopes are atoms having the same number of protons but different number of neutrons. They generally have the same chemical properties. They have the same atomic number but different mass number.

5) located in the nucleus, neutral or no charge : neutrons

Neutrons are subatomic particles in the nucleus with no charges on them.

6) located outside the nucleus, negative(-) charge : electrons

Electrons are subatomic particles that carries negative charges

7) located in the nucleus, positive(+) charger: protons

Protons are positive charges in the nucleus of an atom.

Explain the difference between si base units and derived units. give an example of each
34kurt
Base SI unit is the unit that used for simple quantity like time=second and length= meter. They only have one unit.
Derived unit is more complex because you multiply or divide at least two base SI, making it have more than 1 unit. The example could be velocity which was time/length = m/s

Transcranial magnetic stimulation (TMS) is a noninvasive technique used to stimulate regions of the human brain. A small coil is
attashe74 [19]

Answer:

0.125 volts

Explanation:

The induced emf can be sufficient to stimulate neuronal activity.

One such device generates a magnetic field within the brain that rises from zero to 1.5 T in 120 ms.

We need to find the induced emf within a circle of tissue of radius 1.6 mm and that is perpendicular to the direction of the field. The formula for the induced emf is given by :

\epsilon=-\dfrac{d\phi}{dt}

Where

\phi is magnetic flux

So,

\epsilon=-\dfrac{d(BA)}{dt}\\\\=2\pi r\times \dfrac{dB}{dt}\\\\=2\pi \times 1.6\times 10^{-3}\times \dfrac{1.5-0}{120\times 10^{-3}}\\\\=0.125\ V

So, the induced emf is equal to 0.125 volts.

Trucks can be run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 20
Genrish500 [490]

Answer:

The time it can operate between chargins in minutes is

t=102.8 minutes

Explanation:

Given: m=500kg, r=1.0m, w=200\pi rad/s

a). The rotational kinetic energy

K_R=\frac{1}{2}*I*w^2

I=\frac{1}{2}*m*r^2

I=\frac{1}{2}*500kg*(1.0m)^2

I=250 kg*m^2

K_R=\frac{1}{2}*250kg*m^2*(200\pi rad/s)^2

K_R=49.348x10^6J

b). The power average 0.8kW un range time can be find

P=\frac{K_R}{t'}

Solve to t'

t=\frac{K_R}{P}

t=\frac{49.348x10^6}{0.8x10^3w}=6168.5s

t=6168.5s\frac{1minute}{60s}=102.8 minutes

What controls the traits an organism has?
Charra [1.4K]

The Traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Variant copies of a gene are called alleles, and an individuals genotype is the sum of all the alleles inherited from the parents.
