Explanation:

Ideal Mechanical Advantage (IMA) can be found by using the formula:

IMA = ID/OD

ID = Input Distance

OD = Output Distance

In the question, we are given:

ID = 150

OD = 75

Now, solve the expression with what we have.

IMA = 150/75

IMA = 2

Therefore, the IMA is 2.

Explanation:

Answer:

133.33 mm

Explanation:

First we need to find the volume of the sphere. The volume of a sphere is given by:

V = (4/3) * pi * r^3

With a radius of 10 cm, we have:

V = (4/3) * pi * r^3 = 4188.79 cm3

The sphere will be moulded into a cylinder, so the volume will be the same. The volume of a cylinder is:

V = pi * r^2 * h

Where h is the height of the cylinder, and for this case, it will be the length.

The radius is the same old radius, so we have:

4188.79 = pi * 10^2 * h

h = 4188.79 / 100pi = 13.3333 cm

In millimeters, we have h = 133.33 mm

Answer:

white

Explanation:

This experiment causes lines of different colors because the constructive interference depends on the wavelength, so for different wavelength, the position of the maximum will be different.

Now, in diffraction fo a single slit we always have a central maximum (for all the colors)

This means that after the diffraction, we will have that all the colors have a maximum in the center, which will produce white light again, then the color of the central image is white

Answer:43.6°

Explanation:

Refractive index=n=1.45

Critical angle=c

n=1/sinc

1.45=1/sinc

Cross multiply

1.45sinc=1

Divide both sides by 1.45

(1.45sinc)/1.45=1/1.45

sinc=0.6897

c=sin(inverse)(0.6897)

c=43.6°

Critical angle is 43.6°

Answer: OLEDs

Explanation:

The nanotechnology uses the surface of the carbon materials to generate the electricity. The evaporation of water on the surface of carbon materials helps in generation of electrical energy due to generation of thermal energy.

OLEDs can be defined as solid-state devices that comprises of organic molecules like carbon that will create electricity by exposing a surface for generation of thermal energy.

Explicación:

Se dice que el trabajo se realiza cuando una fuerza aplicada a un objeto hace que el objeto se mueva a través de una distancia. El trabajo realizado por un cuerpo se expresa mediante la fórmula;

Workdone = Fuerza * Distancia

Como Fuerza = masa * aceleración,

Workdone = masa * aceleración * distancia

Masa dada = 5.0kg, aceleración = 2.0m / s² d =?

Para obtener d, usaremos una de las leyes del movimiento,

d = ut + 1 / 2at²

u = 0 (ya que el cuerpo acelera desde el reposo) yt = 7.0s

d = 0 + 1/2 (2) (7) ²

d = 49m

Workdone = 5 * 2 * 49

Workdone = 490 Julios

Answer:

Explanation:

Answer:

F = 592238.09 N

Explanation:

To find the mean force you first calculate the acceleration by using the following kinematic equation:

[tex]v^2=v_o^2+2ax\\\\v_o=0m/s\\\\v=10km/h\\\\x=8.4m\\\\[/tex]

you do "a" the subject of the equation and replace the values of the other parameters:

[tex]a=\frac{v^2}{2x}=\frac{10000m/s}{2(8.4m)}=595.23\frac{m}{s^2}[/tex]

next, the force, by using the second Newton law is:

[tex]F=ma=(1000kg)(595.23\frac{m}{s^2})=595238.09\ N[/tex]

hence, the force is 592238.09 N

Answer:

67.56kg

Explanation:

Fapp+mg = ma

Fapp= applied force

mg = reactional force

g = acceleration due to gravity

Where g = 9.8m/s^2 a= 5 m/s2, Fapp= 1000N.

1000N = ma + mg

1000N = m( a+g )

1000N = m ( 5+9.8)

1000N = m×14.8

m = 1000÷14.8

m = 67.56kg.

Hence the mass of the wagon will be 67.56kg

Answer:

No

Explanation:

She will not be able to measure the length of her window accurately due to instrumental error from her choice of instrument. The elastic nature of her tape would alter the measurement because it will stretch as she is taking her readings, thus reducing the true measurement of the length of her window.

To measure the length of her window, she could use an inelastic tape rule or a metre rule. These instruments would eliminate instrumental error.

Explanation:

English Translation

- Determine the number of protons and neutrons in the nucleus of the atom of beryllium.

- Determine the structure of the nuclei of the isotopes of uranium and thorium

- Which forces are called nuclear forces.

- List the peculiarities of nuclear forces.

Solution

Note that the number of protons in the nucleus of an atom is the atomic number of that atom.

And the mass number of the atom is the sum of protons and neutrons in the nucleus of the atom.

The nucleus of an atom is the most massive part of an atom containing almost exclusively the neutrons and the protons of the atom.

- Beryllium has an atomic number of 4 and a mass number of 9.

Hence, its number of protons = atomic number = 4

(Number of protons) + (Number of neutrons) = mass number

Number of neutrons

= (mass number) - (Number of protons)

= 9 - 4 = 5

- Uranium has atomic number of 92 and mass number of 238.

Number of protons = 92

Number of neutrons = 238 - 92 = 146

Thorium has atomic number of 90 and a mass number of 232.

Number of protons = 90

Number of neutrons = 232 - 90 = 142 neutrons.

- Nuclear forces are the forces that keep the neutrons and protons of an atom bonded to the nucleus of an atom. The constituents of the atom's nucleus are called nucleons. Nuclear forces are the forces between two or more nucleons.

- The nuclear forces are about 10 million times stronger than the forces that bind atoms together in molecules and compounds.

Hence, massive energies are required to break into the nucleus of atoms.

This is why nuclear reactors produce about a million times more energy per kilogram fuel compared to chemical fuel.

However, the range of the nuclear force is short, only about 10⁻¹⁵ m, beyond which it decreases rapidly.

This is why, in spite of its enormous strength, we do not feel anything of this force on the atomic scale or in everyday life.

In Romanian/In limba romana

Rețineți că numărul protonilor din nucleul unui atom este numărul atomic al acelui atom. Și numărul de masă al atomului este suma protonilor și neutronilor din nucleul atomului. Nucleul unui atom este partea cea mai masivă a unui atom care conține aproape exclusiv neutroni și protonii atomului.

- Beriliu are un număr atomic de 4 și un număr de masă de 9.

Prin urmare, numărul său de protoni = numărul atomic = 4

(Număr de protoni) + (Număr de neutroni) = număr de masă

Numărul de neutroni = (număr de masă) - (Număr de protoni) = 9 - 4 = 5

- Uraniul are numărul atomic de 92 și numărul de masă de 238.

Numărul de protoni = 92

Numărul de neutroni = 238 - 92 = 146

Toriul are un număr atomic de 90 și un număr de masă de 232.

Numărul de protoni = 90

Numărul de neutroni = 232 - 90 = 142 neutroni.

- Forțele nucleare sunt forțele care mențin neutronii și protonii unui atom legați de nucleul unui atom.

Constituenții nucleului atomului se numesc nucleoni. Forțele nucleare sunt forțele dintre doi sau mai mulți nucleoni.

- Forțele nucleare sunt de aproximativ 10 milioane de ori mai puternice decât forțele care leagă atomii împreună în molecule și compuși.

Prin urmare, energiile masive sunt necesare pentru a pătrunde în nucleul atomilor.

Acesta este motivul pentru care reactoarele nucleare produc aproximativ un milion de ori mai multă energie pe kilogram de combustibil în comparație cu combustibilul chimic.

Cu toate acestea, domeniul forței nucleare este scurt, doar aproximativ 10⁻¹⁵ m, dincolo de care scade rapid.

Acesta este motivul pentru care, în ciuda puterii sale enorme, nu simțim nimic din această forță pe scara atomică sau în viața de zi cu zi.

Answer:

The electric potential energy between the particles is 2.167 x 10⁻⁸ J

Explanation:

Given;

a charged particle, q₁ = 5.1 nC

another charged particle, q₂ = 2.6 nC

distance between the charged particle, r = 5.5 m

The electric potential energy between the charged particles is calculated as;

[tex]U_E = \frac{kq_1q_2}{r}[/tex]

where;

[tex]U_E[/tex] is the electric potential energy between the particles

k is coulomb's constant = 8.99 x 10⁹ Nm²/c²

Substitute the given values and solve for electric potential energy;

[tex]U_E = \frac{kq_1q_2}{r} = \frac{8.99*10^{9}*5.1*10^{-9}*2.6*10^{-9}}{5.5} \\\\U_E = 2.167 *10^{-8} \ J[/tex]

Therefore, the electric potential energy between the particles is 2.167 x 10⁻⁸ J

Answer:

D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

Explanation:

The continuous flow of charges is known as electricity (current). The flow of these charges are due to free or mobile electron within the atoms of the conductors. The materials which will allow current to pass through them, must have free or mobile electrons which are loosely bound to their atoms.

Thus, the correction for this question is "D"
