Answer:
1. The image is real
2. 5.85
3. h' = 3.05 mm
4. The image is upright
Explanation:
1. Start with the first lens and apply 1/f = 1/p + 1/q
1/5.01 = 1/13.7 + 1/q
q = 7.90 cm
Since that distance is behind the first lens, and the second lens is 62.5 cm behind the first lens, that distance is 62.5 - 7.90 = 54.6 cm in front of the second lens, and becomes the object for that lens, thus,
1/25.9 = 1/54.6 + 1/q
q = 49.3 cm behind the second lens
Using that information, since q is positive, the image is real
2. Also, using that information, you have the second answer, which is 49.3 cm
The height can be found from the two magnifications.
m = -q/p
m1 = -7.9/13.7 = -.577
m2 = -49.3/54.6 = -.903
Net m = (-.577)(-.903) = .521
Then, m = h'/h
.521 = h'/5.85
3. h' = 3.05 mm
4. For the fourth answer, since the overall magnification is positive, the final image is upright
Acceleration is -7 m/s²
Explanation:
initial velocity (u) = 14 m/s
since it's gonna stop,
final velocity (v) = 0m/s
time taken(t) = 2 seconds
now,
a = (v-u)/t
or, a = (0-14)/2
or, a = -14/2
a = -7m/s²

Cool ocean air causes a cool climate.
Explanation:
A large body of water such as an ocean influences climate by causing cool ocean air to provide cool and dry climate.
The climate of place is the extensive weather condition of that place over a long period of time.
- The sun's energy is one factor that contributes largely to the distribution of climates on the earth surface.
- When the surface of the ocean warms, moisture laden air is produced and carried away.
- As they lose their moisture, they become drier and cold thereby causing a cool climate.
