Answer:
<h2>a) -1.93m</h2><h2>b) +0.643</h2>
Explanation:
Image distance and focal length of a convex mirror is negative.
a) Using the mirror formula to determine the image distance;
f = focal length of the mirror = -5.40m
u = object distance from the mirror = 3.00m
v = image distance from the mirror
b) Magnification = image distance/object distance
Magnification = 1.93/3
Magnification = +0.643
<em>Note that we do not use the negative value of the image distance to calculate the magnification of the object</em>

Answer:
Explanation:
Displacement involves direction and distance. In this case, the deer has walked a distance of 17 + 12 = 29m but because of the South-then-North direction, the net displacement is only 17-12 = 5m.
So the answer is A) 5.0 m, 29.0 m
Answer:
Kinetic energy is energy possessed by an object in motion. The earth revolving around the sun, you walking down the street, and molecules moving in space all have kinetic energy. Potential energy is energy an object has because of its position relative to some other object.
Explanation:
5 × 12 = 60 I got 60mph I multiply and that's how I get 60
