The speed of the stone is 9.8 m/s
<u>Explanation:</u>
Given data,
Mass - 3 kg K.E 150-J
We have to find the speed of the stone
We have the formula
K.E =1/2 m× v ²
Rewrite the equation as
v= √ 2×K.E/m
v= √2 ×150/ 3.1
v=9.83 m/s
The speed of the stone is 9.8 m/s

Answer:
use photomath it is amazing
Explanation:
I believe the correct answer is A, Wave 1 has a longer wavelength and a higher amplitude than wave 2. Both A and B are transverse wave, therefore, the wavelength is the distance between two successful crest (highest point) or two successful trough (lowest point). In this case, wave 1 has a longer wavelength than wave 2. Amplitude is the maximum displacement of particles in a wave on either side from the equilibrium point. From the diagram wave 1 as a higher amplitude compared to wave 2.
