Fk = μK N
N = m a
N = 4 × a
N = 4a
Fk = μK N
17 = 5 × 4a
17 = 20 a
a = ¹⁷/₂₀ = 0.85 m/s²
Answer:
B
Explanation:
Because vector Y is longer than vector X
so when you take a magnitude( without minus ) each other
you see that Y>X
The time needed to form a soil depends on the latitude: in environments characterized by a mild climate, it takes 200-400 years<span> to form 1 cm of soil. in wet tropical areas soil formation is faster, as it takes</span>200 years<span>. in order to accumulate enough substances to make a soil fertile it takes </span>3000 years<span>.

Answer:
a) 35.44 mm
b) 17.67 mm
Explanation:
u = Object distance = 3.6 m
v = Image distance
f = Focal length = 35 mm
= Object height = 1.8 m
a) Lens Equation
The CCD sensor is 35.34 mm from the lens
b) Magnification
The person appears 17.67 mm tall on the sensor
