The value of current will remain constant throughout the series circuit.

Answer:

Explanation:

Consider all the resistors are connected in series such that the one end of a resistor is connected to another end of resistor. Similarly, the end of the second resistor is connected to end of third resistor and so on. As there is only one battery connection and this is also given to the first resistor and last resistor. The first resistor is the connected to the positive of battery via wire and the last resistor is connected to the negative terminal of the battery. So the current flow will be constant in all the resistors. As the voltage drop will occur in each of the resistors during passing through it. Thus the current will remain constant while the voltage and resistance will be varying with each other.

So Rs = R1 +R2+ R3 +.....................+R4.

So the value of current will remain constant throughout the series circuit.

Answer:

B = 0.546 T,  F = 2.59 10⁻¹² N

Explanation:

The magnetic force is

            F = q v x B

We can calculate the magnitude of the force and find the direction by the right hand rule

          F = q v B sin θ

Let's use Newton's second law

         F = m a

Acceleration is centripetal

         a = v² / r

We substitute

       q v B sin θ = m v² / r

The angle between the field and the radius of the circle is 90º so sin 90 = 1

        q B = m v / r

        B = m v / q r

Let's calculate ’

       B = 1.67 10⁻²⁷ 2.97 10⁷ / (1.60 10⁻¹⁹ 0.568)

        B = 0.546 T

The foce is

         F = q v B

         F = 1.60 10⁻¹⁹ 2.97 10⁷ 0.546

         F = 2.59 10⁻¹² N

Sí un auto viaja a 8m/s determine Tiempo en llegar a 200km de distancia Distancia que recorre en 40 minutos
GrogVix [38]

Answer:

a. Tiempo = 25000 segundos

b. Distancia = 19200 metros

Explanation:

Dados los siguientes datos;

Velocidad = 8 m/s

Distancia = 200 km a metros = 200 * 1000 = 200,000

Para encontrar el tiempo para cubrir la distancia anterior;

Tiempo = distancia/velocidad

Tiempo = 200000/8

Tiempo = 25000 segundos

b. Para encontrar la distancia recorrida en 40 minutos;

Tiempo = 40 minutos a segundos = 40 * 60 = 2400 segundos

Distancia = velocidad * tiempo

Distancia = 8 * 2400

Distancia = 19200 metros

In the year 1178. five monks at Canterbury Cathedral in England observed what appeared to be an asteroid colliding with the moon
Lubov Fominskaja [6]

Answer: 1.28 sec

Explanation:

Assuming that the glow following the collision was produced instantaneously, as the light propagates in a straight line from Moon to the Earth at a constant speed, we can get the time traveled by the light applying velocity definition as follows:

V = ∆x / ∆t

Solving for ∆t, we have:

∆t = ∆x/v = ∆x/c = 3.84 108 m / 3.8 108 m/s = 1.28 sec

The product or products of a reaction are determined by the type of reaction taking place. true or false
Bess [88]

Answer:

True

Explanation:

The products of a reaction are determined by the type of chemical reaction that are taking place. This is very true.

In chemical reactions, bonds are broken and atoms re-arranged to form new products.

  • By virtue of this, we can predict and know the kind of permissible combinations that can take place.
  • There are different kinds of chemical reaction.
  • They are synthesis, decomposition, single displacement, double displacement reactions e.t.c
  • Knowing these reactions gives insight into the likely products we can obtain.
