I'm not sure but i believe it was telekinesis
Answer:
if we want to find force by using newton's law equation ( f = ma ) we have to use mass and acceleration not velocity ,but in this question they did not mention about acceleration but speed so the answer is D
The correct option is B.
Matter is defined as anything that has mass and occupy space. The kinetic theory of matter states that all matters are made up of huge number of small particles which are in constant motion. These small particles are called atoms. Each atom has sub particles, which are electrons, protons and neutrons. The electrons are in constant motion orbiting the nucleus in which the protons and the neutrons are located. The electrons are able to move about constantly because they possess energy.
speed of sound wave depends on elasticity of medium and density of medium
it is given by formula
now if wave travel through solid then its speed is maximum while if it travel from gas then its speed is minimum
so initially its speed is given as 4000 m/s and suddenly decrease to 1500 m/s
so here we can say that its medium will change from solid to liquid
<em>so sound will encounter with water </em>
A. altitude should be correct
