Oliver builds a circuit connecting a light bulb to a battery with wires, leaving a gap in one of the wires. He places several objects across the gap to close the loop. He wants to see which objects allow electricity to flow and turn on the light bulb. Why do some materials allow electricity to flow through while others do not?
A. Electricity will flow if the atoms in the material are bound tightly to each other.
B. Electricity will flow if the atoms in the material are bound loosely to each other.
C. Electricity will flow if the electrons are bound tightly to their atoms in the material.
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
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"
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.

⦁ How much work is it to lift a 20 kg sack of potatoes vertically 6.5 m?
Answer:
work = 1275.3 J
Explanation:
work = (force)(distance)cosø ------- force = ma
=(mass*acceleration)(distance)cosø
=(20*9.81)(6.5)cos0
=1275.3J
nite that the angle of cosine is the difference between the angle of force and the distance. in this case, the force and the distance are in the same direction. :)
Una caja de 5.0kg de masa se acelera desde el reposo a través del piso mediante una fuerza a una tasa de 2.0 /s2 durante 7.0s encuentre el trabajo realizado sobre la caja
Responder:
490 juliosExplicación:
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
A charged particle of 5.1 nC and another with 2.6 nC are separated by a distance of 5.5 m. What is the electric potential energy between the particles?
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

Diffraction of white light with a single slit produces bright lines of different colors.What is the color of the central image?
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

Em um centro de distribuição uma empilhadeira carrega uma caixa de 1000kg até o caminhão responsável pelo transporte desta carga. Partindo do repouso a empilhadeira precisa percorrer uma certa distância 8,4 m para atingir a sua velocidade máxima de operação 10 k/h. Determine a força média necessária para acelerar essa carga.
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

Each gas sample has the same temperature and pressure. which sample occupies the greatest volume? each gas sample has the same temperature and pressure. which sample occupies the greatest volume? 40.0 gar 20.0 gne 20.0 gh2 4.0 ghe
Answer:
20 gram of H as the greastest volume
Explanation:
Each gas sample has the same temperature and pressure. which sample occupies the greatest volume? each gas sample has the same temperature and pressure. which sample occupies the greatest volume? 40.0 gar 20.0 gne 20.0 gh2 4.0 ghe
Given that,
40.0 g of Ar
20.0 g of Ne
20.0 g of h
24.0 g of he
The ideal gas equation ; Pv = nRT
where P is the pressure, V is the volume, R is the gas constant, T is the temperature, n is the number of mole
which is equal to
n = m / M
where m is the given mass
M is the molar mass
The given gas sample are at the same temperature and pressure,
So, the temperature, pressure and gas constant are fixed.
Therefore the volume is proportional to the given mass and molar mass
V ∝ m/M
Substitute the given mass and molar mass of given masses for comparison
No of mole of Ar = mass / molar mass
= 40 / 40 = 1 mole
No of mole of Ne = mass / molar mass
= 20 / 20 = 1 mole
No of mole of h = mass / molar mass
= 20 / 1 = 20 mole
No of mole of he = mass / molar mass
= 24 / 4 = 6 mole
Hence, 20 gram of H as the greastest volume

A force of 1000 Newtons is used to push a box on a flat floor. It accelerated at a rate of 5 m/s2. What is the mass of the wagon?
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

When a warm air mass and cold air mass come together, like a warm front and cold front, a typical outcome is rain. What explains why rain forms in this situation?
A. The cold air causes the moisture in the warm air to condense and precipitate as rain.
B. The cold air is moving faster than the warm air, which causes rain.
C. Because the cold air is denser, it causes rain.
D. The two air masses neutralize each other, which results in clouds that produce rain.
Answer:
A,when the two air masses meet,the cold air cools the block if warm air,causing it to condense and form stratus clouds( blankets of blank clouds that form when air rises slowly e.g. a warm air mass meets a cold one). Eventually when the cloud becomes saturated precipitation falls from them(precipitation is moisture in any form that falls from the atmosphere).

Answer:
0.25 Hz
4 s
Explanation:
Speed = wavelength × frequency
7 m/s = 28 m × f
f = 0.25 Hz
Frequency = 1 / period
0.25 Hz = 1 / T
T = 4 s
