How long is a string under 240 N of tension whose mass is 0.086 kg if a wave travels through it at a speed of 12 m/s?

Darina [25.2K]

Answer:

The length of the string is 0.051 meters

Explanation:

It is given that,

Tension in the string, T = 240 N

Mass of the string, m = 0.086 kg

Speed of the wave, v = 12 m/s

The speed of the wave on the string is given by :

$v=\sqrt{\dfrac{T}{M}}$

M is the mass per unit length of the string i.e. M = m/l.......(1)

So, $M=\dfrac{T}{v^2}$

$M=\dfrac{240\ N}{(12\ m/s)^2}$

M = 1.67 kg/m

The length of the string can be calculated using equation (1) :

$l=\dfrac{m}{M}$

$l=\dfrac{0.086\ kg}{1.67\ kg/m}$

l = 0.051 m

So, the length of the string is 0.051 meters. Hence, this is the required solution.

A 4g bullet, travelling at 589m/s embeds itself in a 2.3kg block of wood that is initially at rest, and together they travel at

VARVARA [1.3K]

Answer:

The percentage of the kinetic energy that is left in the system after collision to that before is 0.174 %

Explanation:

Given;

mass of bullet, m₁ = 4g = 0.004kg

initial velocity of bullet, u₁ = 589 m/s

mass of block of wood, m₂ = 2.3 kg

initial velocity of the block of wood, u₂ = 0

let the final velocity of the system after collision = v

Apply the principle of conservation of linear momentum

m₁u₁ + m₂u₂ = v(m₁+m₂)

0.004(589) + 2.3(0) = v(0.004 + 2.3)

2.356 = 2.304v

v = 2.356 / 2.304

v = 1.0226 m/s

Initial kinetic energy of the system

K.E₁ = ¹/₂m₁u₁² + ¹/₂m₂u₂²

K.E₁ = ¹/₂(0.004)(589)² = 693.842 J

Final kinetic energy of the system

K.E₂ = ¹/₂v²(m₁ + m₂)

K.E₂ = ¹/₂ x 1.0226² x (0.004 + 2.3)

K.E₂ = 1.209 J

The kinetic energy left in the system = final kinetic energy of the system

The percentage of the kinetic energy that is left in the system after collision to that before = (K.E₂ / K.E₁) x 100%

= (1.209 / 693.842) x 100%

= 0.174 %

Therefore, the percentage of the kinetic energy that is left in the system after collision to that before is 0.174 %

Muitos remédios são tomados em doses menores que o mg. Um comprimido de certo remédio tem 0,025 mg de uma certa substância. Com

Sergio039 [100]

Answer:

Explanation:

<u>The question is asked in portuguese</u>

<u>Hence, it will be answered in portuguese</u>

1kg = 1000g

1 g = 1000mg

então

1 kg = 1 x (1000 x 1000)

1 kg = 1x 1.000.000

1 kg = 1.000.000mg

assim

1 comprimido -------------> 0,025 mg

x comprimido ------------> 1.000.000 mg ( só cruzar)

0,025(x) = 1(1.000.000)

0,025x = 1.000.000

x = 1.000.000/0,025

x = 40.000.000

<h3>1kg são feitos 40.000.000( Quarenta milhões de comprimidos)</h3>
