Answer:

1875 meters

Explanation:

We are given;

  • Velocity of the motorcycle as 90 km/hr
  • Time as 75 seconds

We are required to calculate the displacement;

  • First we will convert speed to m/s
  • The suitable conversion factor will be;

1 m/s = 3.6 km/hr

Therefore, 90 km/hr

= 90 km/hr ÷ 3.6 km/hr per m/s

= 25 m/s

But;

Displacement = Velocity × time

Thus;

Displacement = 25 m/s × 75 seconds

                       = 1875 meters

patriot [66]

Answer:

Matter is everything that surrounds us. It has mass and occupies a place in space. Matter can be described by measuring the value of its properties; for example: density, color, mass, volume, etc.

al ser homogenea no se puede percibir con la vista pero si se le agrega acido sulfurico la reaccion hara que el hidrogeno y el oxigeno se evaporen dejando unicamente una masa negra de carbono

No, ya que, es una mezcla homogénea, es decir,  sus elementos están muy unidos mas no combinados de manera química, es posible separarlos pero con mucha dificultad, por tanto, es imposible diferenciarlos a simple vista. Se sabe que están distribuidos de manera uniforme, su estado es conocido como solución o disolución, tal como es el caso del azúcar.

AysviL [449]

Answer:

-142m

Explanation:

To find the initial position of the car, we can add the displacement.

-245 + 103 = -142

Best of Luck!

Learning Goal: To understand the concepts explaining the operation of transformers.
Alex

Answer:

Part a)

ZERO

Part b)

N = 10 turns

Explanation:

Part a)

As we know that transformer is used to change the input voltage into required output voltage

Here this input and output is considered only when it will change with time as the whole concept is based upon Faraday's law where we need to change the flux with time.

So if we have input Source is DC source then output voltage will be zero as there is no flux change

Part b)

As we know by the principle of transformer

\frac{V_1}{V_2} = \frac{N_1}{N_2}

\frac{500}{25} = \frac{200}{N_2}

N_2 = 10

so total number of turns in secondary coil must be 10
