A linear equation is when each term in the algebraic equation is either a constant or the product has a single variable and a constant.

V = constant Speed = constant Direction = constant Acceleration = 0
It is 15.

Assuming that the wavelength remains constant, the velocity of the rope will also double if the frequency is doubled. This can be seen in the word equation below: speed = frequency x wavelength If we assume that wavelength is a constant...let wavelength = 1 speed = frequency therefore... 2 x frequency = 2 x speed
A linear equation is when each term in the algebraic equation is either a constant or the product has a single variable and a constant.
That depends on what the equation is.
If the equation is y = kx then the constant of proportionality is k.
Not necessarily. The equation of a projectile, moving under constant acceleration (due to gravity) is a parabola - a non-linear equation.
V = constant Speed = constant Direction = constant Acceleration = 0

In a mathematical equation, the constant is defined as a term in the equation that only includes a real number. Since a negative number is a real number, then yes, a negative number can be considered a constant. For example, in the equation 6x -2... -2 would be the constant because it is a term that contains only the real number (-2).
Pressure x Volume = Constant (at a constant temperature).
By the definition of mechanical equilibrium, Yes. Because the sum of forces is equal to zero, it can be seen from the equation F=ma that the total acceleration on the object must be zero in order for the equation to hold. The mass is only a constant in this equation in this situation, and remains unchanged.
Continuity equations describe the movement of constant. Bernoulli's equation also relates to movement, the flow of liquids. For some situations, where the liquid flowing is a constant, both a continuity equation and Bernoulli's equation can be applied.
