magnitude of the net force = mass x acceleraton
= 22 x 2.3
=50.6 N
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:
D. has no overall force acting on it.
Explanation:
Why?
Because in a straight line at the constant speed means the car moving in the same velocity, which is not acceleration neither deceleration, and it cannot be on a downhill slope. So the correct answer is
<h3>→ D. has no overall force acting on it.</h3>
