Answer:
a shiny smooth leaf
Explanation:
A shiny smooth leaf will cause specular reflection. Other choices will cause diffused reflection from the surface.
A specular reflection is similar to how a mirror or smooth surface reflects. The incident light is given off as a single ordered reflection from the surface of a body.
For this to occur, the surface incident must be smooth and without rough patterns on it.
A path way with rough rocks, small patch of soil and rough logs will give off diffused reflection
Answer:
Gamma waves are transmitted by ...... body tissues with very little absorption

<span>Integrate a to get v and use initial data for v to evaluate the constants of integration.
v = [(3/2)t^2 + Ci]i + [2t^2 + Cj]j
When t=0, v = 5i + 2j, hence Ci=5, Cj=2
So v = [(3/2)t^2 + 5]i + [2t^2 + 2]j <==ANS
(b)
Integrate v to get r and use initial data for r to evaluate the constants of integration:
The result is:
r = [0.5t^3 + 5t + 20]i + [(2/3)t^3 + 2t + 40]j <==ANS
Set t=4 in the above expression to evaluate (c)
Convert the result of (c) to polar form to evaluate (d)</span>
100N describes the weight of the sandbag, while 100kg is the mass of the sandbag.
To calculate acceleration, divide your weight by the mass, thus the accleration is:
Answer:
Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element's isotopes. - Mass number: count of the total number of protons and neutrons in an atom's nucleus.
