Answer: 8v
Explanation:
The total voltage drop across the first and second resistor is 8 V, hence option A is correct.
What is Voltage?Voltage is the fluctuation in electric potential between the two places. It is sometimes produced by electric pressure, electric tension, or voltage source. The work required to move a test charge between two places in a static electric field corresponds to this. The derived measure for voltage in the International System of Units is called a volt. Work per unit energy is expressed in SI units as joules per coulomb, with 1 volt equaling 1 joule per 1 coulomb.
To detect the voltages between two locations in a circuit, use a voltmeter. A common reference point, like the system's foundation, is frequently utilized as one of the points.
A voltage can indicate either a supply of energy or its loss, dissipation, or storage.

What would a series circuit be used for?
A. to power a battery
B. to light a lamp
C. as a voltage divider
D. convert chemical energy to thermal energy
Answer:
C
Explanation:
a series circuit would be an odd choice to power a battery or light a lamp when a direct would be much more efficient, and it's not converting types of energy, so C is the best possible answer

When an object slides,there is less friction than when it rolls
Answer:
False
Explanation:
Rolling friction takes place when an object rolls on the surface. Sliding friction takes place when two surfaces are rubbed against each other. Rolling friction is much less than sliding friction for same pair of bodies. When one body rolls upon another, there is theoretically no sliding or slip between them.

An electron acquires 7.45 x 10 ^-16 J of kinetic energy when it is accelerated by an electric field from plate A to plate B. What is the potential difference between the plates, and which plate is at the higher potential?
Answer: Kinetic energy of electron = 7.45 x 10^-16 J We know that Potential difference = Work done per unit charge = Kinetic energy of electron / ( 1.6 x 10^-19 ) = (7.45 x 10^-16) / ( 1.6 x 10^-19) = 4656.25 V
Explanation:
The potential difference between the plates is [tex]4650.43V[/tex]
The Potential difference is also defined as the work done per unit charge.
Work done = kinetic energy = [tex]7.45*10^{-16}J[/tex]
Charge on one electron = [tex]1.602*10^{-19}C[/tex]
Potential difference,
[tex]V=\frac{7.45*10^{-16}}{1.602*10^{-19} }=4650.43Volt[/tex]
Hence, the potential difference between the plates is [tex]4650.43V[/tex]

A. friction
B. gravity
C. normal force
D. push
Answer:
B. gravity
Explanation:
The ball if moving down so gravity is acting on it because it is pulling it down to earths toward the center of earth aka the ground.
the net force acting on the ball below is ___ N
The net force applied to the object equals the mass of the object multiplied by the amount of its acceleration." The net force acting on the soccer ball is equal to the mass of the soccer ball multiplied by its change in velocity each second (its acceleration).
Un texto de opinión sobre la situación actual del rol de la mujer, el trabajo y las situaciones de violencia en el contexto de Pandemia. Cambió la situación de las mujeres?
Explanation:
Los derechos de las mujeres fueron conquistados a través de importantes luchas llevadas a cabo por mujeres, como el movimiento feminista que tuvo lugar a fines del siglo XIX, cuyo principal reclamo fue el derecho al voto de las mujeres.
Con el tiempo, las mujeres ganaron más derechos y una mayor participación en el mercado laboral y en puestos importantes de la sociedad. Pero aún queda mucho por cambiar, ya que las estadísticas aún muestran que hay pocas mujeres en posiciones de poder en relación a los hombres, y el salario de una mujer que ocupa el mismo puesto que un hombre es siempre menor.
Dado que la sociedad se concibió a través de parámetros sexistas, lo que continúa en la actualidad, es claro que en la pandemia específicamente que generó crisis económicas en todo el mundo, se vio a una gran cantidad de mujeres perder sus empleos, además del expresivo número de casos de violencia doméstica que se agravaron en el período de aislamiento social.
Así que estos hechos solo demuestran que la lucha por la igualdad de género y los derechos de las mujeres aún están en sus inicios, a pesar de muchos logros que las mujeres aún deben luchar por lo básico, que es el apoyo social y político además de una legislación más estricta que castiga con más rigor a las agresoras. Las mujeres deben estar protegidas por la ley y las instituciones y los medios de comunicación deben abordar más el tema y promover el feminismo como una lucha por la igualdad.

A model rocket accelerates at 15.3 m/s2 with a force of 44 N.
Calculate the mass of the rocket. Round your answer to the nearest tenth of a kg.
The mass of the rocket is kg.
Fill in the blank above. Also what is the formula to find the mass. Include that in the answer pls.
Answer:
According to Newton's Second Law of Motion :
Where,
F = Force Applied
m = Mass of the object
a = Acceleration
Now, we will use this law to solve this question.
Given :
Acceleration or a = 15.3 m/s²
Force = 44 N
Mass = ?
Substitute, the given values in the formula.
F = ma
⇒ m = F/a
m = 44/15.3
m = 2.9 kg

Radio telescopes beam radio waves into space. To calculate the speed of the radio waves in space, which information, if any, is necessary?
Answer:
No more information is needed
Explanation:
Radio waves are electromagnetic energy, lower frequency forms of this type of energy that includes light and cosmic rays on the high frequency end that we are able to detect. So in free space (vacuum), radio waves travel at their fastest velocity, the “speed of light”. The reason for the quotation marks is because when light or radio waves are propagating through matter, we observe them traveling more slowly.

How far can you get away from your little brother with the squirt gun filled with paint if you can travel at 3 m/s and you have 0.25 min before he sees you?
Answer:
s = 45 m
Explanation:
The velocity given in the question is uniform. Hence, the formula for the uniform velocity shall be used here. The formula is given as follows:
[tex]s = vt[/tex]
where,
s = distance traveled away from the brother = ?
v = constant speed = 3 m/s
t = time taken = (0.25 min)(60 s/1 min) = 15 s
Therefore, using these values in the formula we get:
[tex]s = (3\ m/s)(15\ s)\\[/tex]
s = 45 m
