A wave is sent along the first rope transmitting a power of 57.3 W. It has a wavelength of 5.54 cm and velocity of 13.87 m/s The
Serhud [2]

Answer:

A = 2.43*10^{-3} m

Explanation:

power through string can be determined as shown in figure

P  = 2\pi ^2 HVA^2F^2

Where

P = 57.3 W

V = 13.87 m/s

H = 567 g/m

we know that

V = f *\lambda\lambda = \frac{v}{f}

therefore P  = 2\pi ^2 HVA^2(\frac{v}{f})^2

57.3 = \frac{2\pi ^2 * 0.567 *13.87^{3}* A^2}{(5.54*10^{-2})^2}

A = 2.43*10^{-3} m

Why did Galileo use a thought experiment instead of working with real objects
Alja [10]

Answer:

Galileo thought that a ball, rolling or sliding down a hill without friction, would run up to the same height on an opposite hill.

Suppose that the opposite hill was horizontal. Would the ball's motion continue forever along the tangent, or forever parallel to the Earth's surface

Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity.

Newton took this as his first law of motion.
