Answer:

La cinemática es la parte de la física que estudia el movimiento, sin importar la causa que lo produce, es

decir, su objetivo es describir cómo se mueve un cuerpo. En esta materia introductoria, esta descripción será

independiente de la forma y tamaño de los cuerpos en movimiento. Hablaremos del movimiento de un

átomo, de una pelota o de un tren, sin embargo, a los fines prácticos siempre vamos a pensar al objeto en

cuestión como una partícula o cuerpo puntual.

Decimos que una partícula se mueve si la vemos cambiar de lugar, es decir que ocupa distintas posiciones

en distintos instantes. Entonces, la idea de movimiento relaciona el espacio y el tiempo.

Para poder encarar el tema, es necesario definir algunos conceptos que permitan “medir” las características

del movimiento de un cuerpo. Estos conceptos en física se denominan magnitudes y pueden ser vectoriales o

escalares.

La posición, el desplazamiento, la velocidad y la aceleración son magnitudes vectoriales. El tiempo y el

lapso son magnitudes escalares. Asimismo, definiremos otros conceptos como: distancia, trayectoria y

sistemas de referencia.

Veremos que describir el movimiento de un cuerpo/objeto implicará conocer su posición, velocidad y

aceleración en función del tiempo. Para lograr esa descripción será necesario definir un sistema de referencia

para la posición y otro para el tiempo.

A radio telescope detects an incoming radio wave which has a power of 1.00 x 10-24 W. If this signal creates a potential of 1.00
soldier1979 [14.2K]

Answer:

Therefore, the number of electrons moving through the receiver circuit per second is 6250 electrons/s.

Explanation:

Given:

Power of radio wave, P = 1 × 10⁻²⁴ W

Potential of signal, V = 1 × 10⁻⁹ V

Solution:

Consider the number of electrons flowing through the receiver circuit per second be 'n'.

The current flowing through the circuit will be:

I = P/V

 = (1 × 10⁻²⁴ W)/(1 × 10⁻⁹ V)

 = 1 × 10⁻¹⁵ A

Then, the number of electrons moving through the receiver circuit can be  calculated as:

ne = I

where, e is charge on an electron

            I is current flowing through the circuit

Applying values in above equation we get:

n(1.6×10⁻¹⁹ C) = (1 × 10⁻¹⁵ A)

n = (1 × 10⁻¹⁵ A)/(1.6×10⁻¹⁹ C)

n = 6250 electrons/s

Therefore, the number of electrons moving through the receiver circuit per second is 6250 electrons/s.

ANSWER ASAP
Galina-37 [17]

Answer:

I'm not great at science, but I believe that the answer is elastic potential energy.

Explanation:

Components of mechanical systems store elastic potential energy if they are deformed when forces are applied to the system. Energy is transferred to an object by work when an external force displaces or deforms the object.

Mila [183]

Since the biker is moving at constant speed

so we will have

v = \frac{distance}{time}

here we know that

distance = 2\pi R

time = 4 second

now we have

v = \frac{2\pi R}{4} = \frac{\pi R}{2}

now at the top point it feels free fall

so it is

mg = \frac{mv^2}{R}

v^2 = Rg

(\frac{\pi R}{2})^2 = Rg

R = \frac{4g}{\pi^2}

so height of the bike at the top is same as diameter

h = 2R

h = \frac{8g}{\pi^2} = 7.95 meter

Yes it will hurt on falling from this height
