Answer:

Option B

Explanation:

The correct answer is Option B

After leaving the spoon of copper , steel and wooden in the soup for several minute chef can grab Wooden spoon with bare hand.

Wooden material are insulator of heat means heat does not transfer through the wooden material.

where as heat transfer take place in steel as well as copper and chef will not be able to lift the spoon bare hand.

A harmonic wave is traveling along a rope. The oscillator that generates the wave completes 40.0 vibrations in 22.3 s. A given c
Dmitrij [34]

Answer:

Explanation:

frequency of vibration

n = 40 / 22.3 per second.

= 1.794 per second

velocity of wave v = 369 / 13.5 cm / s

= 27.33 cm / s

wavelength = velocity / frequency

= 27.33 / 1.794

= 15.23 cm

Answer:

the total energy before collision is 12.25J

the total energy after collision is tranfered to sound and heat (by the friction between the two clay balls)

Explanation:

first we should know the velocity of the 2 balls:

momentum=mass ×velocity

we have the momentum and the mass of the 2

so momentum ÷mass=velocity

clay ball 1 velocity=7 m/s & clay ball 2 velocity= -7 m/s

KE=1/2 mv²

1/2 ×0.25×7²=6.125J KE of ball 1

1/2 ×0.25×-7²=6.125J KE of ball 2

add them both we will have 12.25J which is before collision

this energy will then be tranfered to heat and sound as they stop after the collision(velocity =0m/s)
