Answer: 
Explanation:
A direct proportionality means a linear relationship between two variables and rate of change means an application of derivatives. Hence, the mathematical model is:
90km per hour. Speed = distance÷time Speed= 225/2.5. Speed = 90Km per hour
Initial Velocity = 0
Final Velocity=3
Duration of time=0.5
Acceleration=6
I hope that helped. Good luck!
Answer:
distance is 139.2 cm
image is inverted and virtual
and 79.36 cm in front of 2nd lens
Explanation:
Given data
convex focal length = 24 cm
distance = 50 cm
concave focal length = -42 cm
light bulb height = 2 cm
distance = 29 cm
to find out
Determine the distance and orientation and image real or virtual
solution
we apply here lens formula for convex
1/f = 1/p + 1/q
here f = 24 and p = 29 so find q
1/24 = 1/29 + 1/q
q = 139.2 cm
so distance is 139.2 cm
and
lens formula for concave
f = - 42 and p = 50 - 139.2 = -89.2 cm so find q
1/f = 1/p + 1/q
- 1/42 = - 1/89.2 + 1/q
q = −79.36 cm
so image is inverted and virtual
and 79.36 cm in front of 2nd lens
