Near the surface of Earth, an electric field points radially downward and has a magnitude of approximately 100 N/C. 1) What char
scoundrel [369]

Answer:

-2.50\times10^{-4} \text{ C} or -0.000250 C

Explanation:

The field points downward, which is the direction of a positive charge. In order for the penny to rise, it has to have a negative charge since its direction is opposite that of the field.

To calculate the magnitude of the charge:

The penny is to accelerate upward so it must overcome gravity. Hence, the net force to cause it to accelerate it upward is the difference between the electrostatic force and its weight.

F_N = F_E - W

F_E = F_N + W

F_E = ma + mg

F_E = m(a + g)

F_E = 0.0025(0.19+9.8)

F_E = 0.0025\times9.99

Now, the electric field intensity is given by

F_E = E \times q

where q = charge

q=\dfrac{F_E}{E}

q=\dfrac{0.0025\times9.99}{100}=0.00024975= 0.000250 to 3 significant figures.

In standard form, q = -2.50\times10^{-4} \text{ C} The negative sign indicates it has a negative charge, as explained initially.

Define "increased productivity" in terms of the number of tasks and the amount of time.
vovikov84 [41]

Answer:

The greater the amount of output for a given unit of input, the higher the overall productivity. Businesses generally aim to improve productivity over time to maintain competitiveness and increase the business's profitability. Individuals are familiar with the idea of productivity in their own lives.

Si aplicamos una fuerza constante de 30 N sobre un cuerpo de 25 Kg, este se mueve de tal manera que en 5 s adquiere la velocidad
Ganezh [65]

Answer:

<em>Si hay rozamiento y el valor de la fuerza de roce es 10 N</em>

Explanation:

<u>Fuerza Neta</u>

La fuerza neta sobre un cuerpo es la suma vectorial de todas las fuerzas actuantes sobre el mismo.

Si conocemos el módulo de la fuerza neta F y la masa m del cuerpo, aplicamos la segunda ley de Newton para relacionarlas con la aceleración a:

F=m.a

Tenemos los datos cinemáticos de la situación, según la cual el cuerpo adquiere una velocidad (desde el reposo) de 4 m/s en 5 s.

Utilizamos la fórmula:

v_f=v_o+a.t

Y despejamos la aceleración:

\displaystyle a=\frac{v_f-v_o}{t}

\displaystyle a=\frac{4-0}{5}

a=0.8 \ m/s^2

Podemos calcular la aceleración real que el cuerpo adquiere, producto de una fuerza efectiva igual a:

F_e=25\ Kg\cdot 0.8 \ m/s^2

F_e=20\ N

Si se está aplicando una fuerza de F_a= 30 N y solo 20 N producen movimiento, entonces se está perdiendo en rozamiento una fuerza:

F_r=F_a-F_e=30 - 20=10

F_r=10\ N

Si hay rozamiento y el valor de la fuerza de roce es 10 N

What is the wavelength of a sound wave that has a speed of 327 m/s and a frequency of 185 hz?
kiruha [24]
Wave speed = frequency * wavelength
We need to rearrange this so wavelength is the subject. To do this, divide both sides by frequency to get :
Wave speed / frequency = wavelength
327 / 185 = 1.7675 m
