<span>Viscosity, the more a fluid resists flow, the more viscous the flow. For example, honey is a very viscous fluid, while water is not as viscous. Hope this helps(:</span>
As the skateboard rolls down the ramp it loses potential energy and gains kinetic energy.
The maximum height reached by the water before it starts coming back down is 40 m.
<h3>
Maximum height reached by the water</h3>
The maximum height reached by the water before it starts coming back down is calculated by applying the principle of conservation of energy.
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
h = (v²)/(2g)
h = (28²)/(2 x 9.8)
h = 40 m

Due to the difference ofwavelength, blue has short wavelenght compared with red(red has long wavelength)
Answer:
The essential characteristics of an object in equilibrium is acceleration of the object must be zero.
Explanation:
Equilibrium: An object acted upon by several forces is said to be in equilibrium if it does no it moves or rotate. Equilibrium can be defined as the state of stability of an object.
Condition for equilibrium
(i) The resultant force acting on the object must me equal to zero.
(ii) The sum of moment acting on the object must be equal to zero.
But.
F = ma..................... Equation 1
Where F = net force , m = mass, a = acceleration.
from the equation above,
For F = 0 N, a must be equal to zero.
<em>From the above, the essential characteristics of an object in equilibrium is acceleration must be zero</em>
