Answers

Answer:

In other words, Tension (Ft) = Force of gravity (Fg) = m × g. Assuming a 10 kg weight, then, the tension force is 10 kg × 9.8 m/s2 = 98 Newtons.

tension= force of gravity= m x g

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.

in each of the following divide the second number by the first number and find the quotient:3/4,-3/8​

Answers

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)

difference of +12.0 V, its electric
potential energy increases by
0.418 J. What is the amount
of the charge?
Include the correct sign, + or -
(Unit = C)

Answers

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

A runner slows down after completing works her deceleration is 0.25m/s after 5 sec she is traveling at 4m/s determine her initial velocity

Answers

Answer:

vi = 5.25 m/s

Explanation:

We can determine the initial velocity of the runner by using the first equation of motion, as follows:

[tex]v_f = v_i + at\\[/tex]

where,

vf = final speed of the runner = 4 m/s

vi = initial speed of the runner = ?

a = deceleration of the runner = - 0.25 m/s²

t = time taken = 5 s

Therefore,

[tex]4\ m/s = v_i + (-0.25\ m/s^2)(5\ s)\\v_i = 4\ m/s + 1.25\ m/s\\[/tex]

vi = 5.25 m/s

En un tiempo de 60 s (segundos), una masa de 0,0014 kg, cambia su velocidad de 25 m/s a 60 m/s. Determine qué fuerza actúa sobre el mismo.

Answers

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

Answers

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

Suppose that the ultrasound source placed on the mother's abdomen produces sound at a frequency 2 MHz (a megahertz is 10^610 ​6 ​​ Hz). Sound travels through tissue at roughly the same speed as in water (v\approx 1500v≈1500m/s). Find the maximum change in frequency between the sound that is emitted by the device and the sound that is observed at the wall of the baby's heart. Treat the heart wall as a moving observer. Hint: you will need to use your answer from part (a). Give your answer as a positive number in Hz.

Answers

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
