Answer:

False

Explanation:

This statement is False.

The atom is made up of nucleus in which there are neutrons and protons and electrons which are revolving around the atom's nucleus.

nuclear energy is basically energy the source of which is nucleus of the atom. there are two methods by which nuclear energy is produces.

1) Nuclear fission

2) nuclear fusion

In nuclear fission, the neutron is bombarded on the nucleus of an atom of an element. It splits and produces a daughter nucleus, neutrons and huge amount of energy

In nuclear fusion, two nuclei of the atoms fuse and produce huge amount of energy.

In both of above mentioned cases, there is neither any role of electrons to produce energy nor in storing nuclear energy.

So, the given statement is wrong

Key words: Nucleus, Nuclear energy, electron, Nuclear fission, Nuclear fusion, neutrons, atom

False. The nuclear energy is found within the nucleus. Electrons are located outside the nucleus.

A particle is moving in a circular path of radius r . The displacement after half a circle would be

Art [367]

Answer:

Explanation:

As we know that

The displacement is the total distance measured between the initial or start and final or destination point

If particle cover half path of the circle, the displacement can easily find out by considering the distance between the start and destination point

We attached the diagram for better understanding

As per the diagram.

The displacement after half-circle is

AB = OA + OB

= r + r

= 2r

A constant-volume perfect gas thermometer indicates a pressure of 6.69 kPa at the triple point temperature of water (273.16 K).

mina [271]

Answer:

(a) ΔP=0.0245 kPa

(b) P=9.14 kPa

(c)ΔP=0.0245 kPa

Explanation:

(a) As it is perfect gas we can use

(P₁V₁)/T₁=(P₂V₂)/T₂

Since this constant volume so

P₁/T₁=P₂/T₂

T₂ is change in temperature

T₂=1.00+273.16

T₂=274.16 K

$P_{2}=(\frac{6.69}{273.16} )*274.16\\P_{2}=6.71449 kPa$

ΔP=6.71449-6.69

ΔP=0.0245 kPa

(b) As

$P_{2}=(\frac{6.69}{273.16} )*373.16\\P_{2}=9.14 kPa$

(c) Same steps as in part (a)

$P_{2}=(\frac{9.14}{373.16} )*374.16\\P_{2}=9.164kPa$

ΔP=9.164-9.14

ΔP=0.0245kPa

An organ pipe is open at both ends. It is producing sound

ozzi

To solve this problem we will apply the concepts related to the wavelength of its third harmonic.

It describes that the wavelength is equivalent to

$\lambda = \frac{2}{3}L$

Here,

$\lambda = Wavelength$

The wavelength is in turn described as a function that depends on the change of the speed as a function of the frequency, that is to say

$\lambda = \frac{v}{f}$

In this case the speed is equivalent to the speed of sound and the frequency was previously given, therefore

$\lambda = \frac{343}{262}$

$\lambda = 1.3091m$

Finally the length of the pipe would be

$L= \frac{3}{2}(1.3091)$

$L = 1.963m$

A girl sits on a tire swing and is pushed in a circular motion by her father. Her tangential speed is 2.8 m/s and the girl trave

Jet001 [13]

Formula: Ca=Vt^2/r

centripetal acceleration(Ca)= ?
tangential speed(Vt)= 2.8m/s
Radius(r)=2m

Substitute: Ca=2.8^2/2
Ca=3.92m/s^2

Elements that typically give up electrons CHECK ALL THAT APPLY

lys-0071 [83]

Answer:

B. have a lower ionization energy

D. are metals

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.

Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.

Typically, valency is measured by the amount of hydrogen atoms that a chemical element can combine with or displace to form a molecule or chemical compound.

Ionization energy can be defined as the minimum energy required to remove or detach an electron from a neutral atom in a gaseous state.

Generally, the ionization energy of chemical elements tend to increase from left to right across a period on the periodic table. This increase is due to the fact that the atomic radius of chemical elements generally decreases across the periodic table, typically from alkali metals (group one elements such as hydrogen, lithium and sodium) to noble gases (group eight elements such as argon, helium and neon) i.e from left to the right of the periodic table. Also, the atomic radius of a chemical element increases down each group of the periodic table, typically from top to bottom (column).

This ultimately implies that, atoms with relatively large atomic radii tend to have a low electron affinity and a low ionization energy.

In conclusion, chemical elements that typically give up electrons are metals because their outermost shell contains excess electrons and have a lower ionization energy.
