<span> The term for the depth of the water needed to make a boat afloat is called the draft of the boat. It can be measured as the distance from the water surface down the lowest point of the vessel. It can be imagined as the submerged portion of the boat during navigation.</span>
From the information given,
diameter of ornament = 8
radius = diameter/2 = 8/2
radius of curvature, r = 4
Recall,
focal length, f = radius of curvature/2 = 4/2
f = 2
Recall,
magnification = image d
Answer:
106.25 m
Explanation:
Acceleration a = force / mass
= 40 / 80 = 0.5 m /s²
initial velocity u = 20 m /s
a = 0.5 m /s²
time t = 5 s
displacement s = ?
s = ut + 1/2 a t²
= 20 x 5 + .5 x .5 x 5²
= 100 + 6.25
= 106.25 m .
