<u>A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element</u>.
Resistors reduce the current flow and lower voltage levels within circuits.
A <u>circuit is said to be connected in series</u> when the same amount of <u>current flows through the resistors</u>. In such circuits, the voltage across each resistor is different.
In a series connection, if any resistor is broken or a fault occurs, then the entire circuit is turned off. The construction of a series circuit is simpler compared to a parallel circuit.
For the above circuit(attached image-1), the total resistance is given as:
The total resistance of the system is just the total of individual resistances.
A <u>circuit is said to be connected in parallel</u> when the <u>voltage is the same across the resistors</u>. In such circuits, the current is branched out and recombines when branches meet at a common point.
A resistor or any other component can be connected or disconnected easily without affecting other elements in a parallel circuit.
The figure(attached image -2) above shows ‘n’ number of resistors connected in parallel. The following relation gives the total resistance here
The sum of reciprocals of resistance of an individual resistor is the total reciprocal resistance of the system.

Answer:
A. 159 hertz
Explanation:
To find the frequency of a wave you have to divide the velocity (speed) by the wavelngth.
342 divided by 2.15 is 159.
To solve this problem it is necessary to apply the concept related to root mean square velocity, which can be expressed as
Where,
T = Temperature
R = Gas ideal constant
n = Number of moles in grams.
Our values are given as
The temperature is
Therefore the root mean square velocity would be
The fraction of velocity then can be calculated between the escape velocity and the root mean square velocity
Therefore the fraction of the scape velocity on the earth for molecula hydrogen is 0.1736
Answer:
El avión recorrió 45 km en los 180 s.
Explanation:
La relación entre velocidad, distancia y tiempo se da de la siguiente manera;
Por lo cual los parámetros dados son los siguientes;
Velocidad = 900 km/h = 250 m / s
Tiempo = 180 s
Estamos obligados a calcular la distancia recorrida
De la ecuación para la velocidad dada arriba, tenemos;
Distancia recorrida = Velocidad pf viaje × Tiempo de viaje
Distancia recorrida = 900 km/h × 180 s = 900
Distancia recorrida = 900 km/h × 1 h/60 min × 1 min/60 s × 180 s = 45 km
Por lo tanto, el avión viajó 45 km en 180 s.
