Answer:

[tex]\dfrac{-1}{2}[/tex]

Explanation:

We need to divide the second number by the first number and the numbers are 3/4,-3/8​.

First number = 3/4

Second number = -3/8

Dividing the second number by the first number.

So,

[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}[/tex]

We know that,

[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]

So,

[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}=\dfrac{-3}{8}\times \dfrac{4}{3}\\\\=\dfrac{-1}{2}[/tex]

So, the answer is (-1/2)

Answer:

daughters cells

Explanation:

when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself.

Answer:

Fuerza = 0.0082 Newton

Explanation:

Dados los siguientes datos;

Velocidad inicial, u = 25 m/s

Velocidad final, v = 60 m/s

Tiempo, t = 60 segundos

Masa = 0,0014 kg

Para encontrar la fuerza que actúa sobre el objeto;

En primer lugar, determinaríamos la aceleración del objeto.

Aceleración = (v - u)/t

Aceleración = (60 - 25)/60

Aceleración = 35/60

Aceleración = 5.83 m/s²

A continuación, encontramos la fuerza;

Fuerza = masa * aceleración

Fuerza = 0.0014 * 5.83

Fuerza = 0.0082 Newton

Answer:

The closer and bigger the star, the larger the star appears.

Explanation:

Since the sun is closer to us it shows up way larger than other stars in our galaxy.

Have a great day.

Answer:

It is the closest star to us. other bigger stars may seem small, but that is because they are far away. The more closer an object is, the smaller it seems to be.

Answer:

[tex]fr = \frac{9 \times 10 {}^{9} \times 3 \times 4}{2 {}^{2} } \\ fr = 27 \times 10 {}^{9} n[/tex]

Answer:

The force of gravity exerts a downward force. The floor exerts an upward force. Since these two forces are of equal magnitude and in opposite directions, they balance each other.

Answer:

the maximum frequency observed is 2.0044 10⁶ Hz

Explanation:

This is a Doppler effect exercise. Where the emitter is still and the receiver is mobile, therefore the expression that describes the process is

          f ’= [tex]f_o \ ( \frac{v \pm v_o}{v} )[/tex]

the + sign is used when the observer approaches the source

typical speeds of a baby's heart stop are around 200 m / min

let's reduce to SI units

        v₀ = 200 m / min (1 min / 60 s) = 3.33 m / s

let's calculate

         f ’= 2 10⁶ ([tex]\frac{1500 \ \pm 3.33}{1500}[/tex])  

         f ’= 2.0044 10⁶ Hz

         f ’= 1,9956 10⁶ Hz

therefore the maximum frequency observed is 2.0044 10⁶ Hz

Answer:

+ 0.07 C

Explanation:

From the question given above, the following data were obtained:

Potential difference (V) = 12 V

Energy (E) = 0.418 J

Charge (Q) =?

The energy (E) , potential difference (V) and charge (Q) are related by the following equation:

E = ½QV

With the above formula, we can obtain the charge as follow:

Potential difference (V) = 12 V

Energy (E) = 0.418 J

Charge (Q) =?

E = ½QV

0.418 = ½ × Q × 12

0.418 = Q × 6

Divide both side by 6

Q = 0.418 / 6

Q = + 0.07 C

Answer:

Explanation:

306.12 Kg,

Answer:

The mass of an object weighing 3000N is 300kg

Explanation:

Here,

Weight (W) = 3000N is given

So,

we will use

W = mg

where,

m = mass of the body

g = acceleration due to gravity

Now,

W = mg

3000 = m × 10

m = 3000 ÷ 10

m = 300kg

Thus, The mass of an object weighing 3000N is 300kg
