Answer:

ok

Explanation:

if you bang a drum, the salt will obviously jump up and that is because of vibration and sound waves. the sound wave causes the salt to vibrate and the pressure on the drum will make the salt jump

Write about the similarities and differences between kinetic and potential energy. Include specific, real world example in your
lord [1]

Answer:

Energy is transformed from potential to kinetic and vice versa

Explanation:

The energy is transformed from mechanical to kinetic energy when the object changes its position with respect to a reference point, where it loses height but increases its speed. When the object is at maximum height with respect to a reference point, it will have its maximum potential energy value. When the object passes through the reference point it will have potential energy equal to zero, but this energy will become kinetic energy.

The most characteristic and real example is that of a pendulum at one end, as can be seen in the attached image.

When the pendulum is located at the top end, as shown in Figure 1, at that point the maximum potential energy will be held. Then the pendulum is released and when it passes through the reference point and its height is zero, with respect to that point, all potential energy will have become kinetic energy in the same way at this point the maximum speed of the pendulum will be set.

A heavy piece of hanging sculpture is suspended by a90-cm-long, 5.0 g steel wire. When the wind
Yuliya22 [10]

As we know that fundamental frequency is given as

f = \frac{1}{2L}\sqrt{\frac{T}{\mu}}

here we know that

\mu = \frac{m}{l}

here we have

m = mass of wire = 5 g

l = length of wire = 90 cm

\mu = \frac{0.005}{0.90} kg/m

\mu = 5.56 \times 10^{-3} kg/m

from above formula now

80 = \frac{1}{2(0.90)}\sqrt{\frac{T}{5.56\times 10^{-3}}}

144 = \sqrt{180 T}

T = 115.2 N

now we know that tension is due to weight of the sculpture so we will have

Mg = 115.2 N

M = 11.76 kg

so its mass will be 11.76 kg

-Para lograr que una pieza de 0,300 kg de cierto metal aumente su temperatura desde 40°C a 60 °C ha sido necesario suministrarle
marishachu [46]

Answer:

parte a) el calor específico es c = 0.383 J /(gr*K)

parte b) la temperatura inicial es T inicial= 52.72 °C

Explanation:

para el primer punto la formula para el calor Q es:

Q = m * c * ( T final - T inicial )

donde

m= masa de la pieza = 0.300 kg = 300 gr

Q = flujo de energía en forma de calor= 2299 J

c = calor específico

T final = temperatura final =40°C

T inicial = temperatura inicial = 60 °C

entonces

Q = m * c * ( T final - T inicial )

c = Q / [ m* ( T final - T inicial ) = 2299 J/[ 300 gr  * ( 60 °C - 40°C )]

= 0.383 J /(gr*K)

c = 0.383 J /(gr*K)

para el segundo punto usamos la misma formula

Q = m * c * ( T final - T inicial )

pero

m= 200 gr= 0.200 kg

c=459.8 J/(kg*K) , Q =20.900 J , T final = 280 °C

Q = m * c * ( T final - T inicial )

T inicial = T final - Q/(m*c)  =280 °C - 20.900 J/(459.8 J/(kg*K)* 0.200 kg) = 52.72 °C
