Answer:
Sand,Mud
Explanation:
Sugar and salt are examples of soluble substances. Substances that do not dissolve in water are called insoluble. Sand and flour are examples of insoluble substances.
Power P is the rate at which energy is generated or consumed and hence is measured in units that represent energy E per unit time t. This is:
P = E/t
Solving for t:
t = E/P
t = 6007 J / 500 W
t = 12.014 s
<h2>
t ≅ 12 s</h2>
Answer:
The vector equation of the line is

Parametric equations for given line are

Explanation:
The vector equation of the line is given by

r₀ = (7, -8, 3)
v = (1, 6, -13)
At these points the vector equation for this line is:

Parametric equations for given line are

Answer:
it's possible to calculate an object's velocity at any moment along its path. This is called instantaneous velocity and it is defined by the equation v = (ds)/(dt),in other words, the derivative of the object's average velocity equation.
