What two factors will most likely change the speed of a mechanical wave?

Speed of mechanical wave (sound wave) is given by the formula

here we can say that speed of sound wave depends on two factors

1). E = elasticity

2). = density

also we can have the string wave speed given by the equation as

here we can say it will depends on

1). T = tension in the string

2) = linear mass density

Also we will have the speed of sound in gases given as

here it depends on two factors as

1). = Type of gas

2). T = temperature of gas

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
