Answer: the photograph will likely show only one star.
Explanation:
Since their angular separation is smaller than the telescope's angular resolution, the picture will apparently show only one star rather than two.
Answer:
Height above the floor from the bottom is 0.82m
Form the top is 1.71m

Answer:
122.735 behind converging lens ; 2.16
Explanation:
Given tgat:
Object distance, u = 29 cm
Image distance, v =
Focal length, f = - 19 (diverging lens)
Mirror formula :
1/u + 1/v = 1/f
1/29 + 1/v = - 1/19
1/v = - 1/19 - 1/29
1/v = −0.087114
v = −11.47916
v = -11.48
Second lens
Object distance :
u = 11.48 + 11 = 22.48 cm
1/v = 1/19 - 1/22.48
1/v = 0.0081475
v = 1 / 0.0081475
v = 122.735 cm
122.735 behind second lens
Magnification, m
m = m1 * m2
m = - v / u
Lens1 :
m1 = -11.48 / 29 = - 0.3958620
m2 = - 122.735 / 22.48 = - 5.4597419
Hence,
- 0.3958620 * - 5.4597419 = 2.16
<span>So are strong bases. The reason acids and bases conduct electricity is that when they are mixed with water, they "separate" into ions. And the ions are charge carriers. These charge carriers can be made to carry a charge (which is why that description fits them).</span>
The boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.
Explanation:
Velocity is the rate of change of displacement with time. It is a physical quantity that has both magnitude and direction.
When expressing velocity, we must consider the directional attribute as it distinguishes it from speed.
Statements:
The hiker began hiking the park's five-mile north hiking trail at 8:00 a.m. with plenty of daylight left to complete the hike before dark.
We are given the displacement of the hiker but the duration of traveling was not indicated. The starting time is known and there is nothing we can infer from it
The motorcyclist traveled along a highway at 55 mph and reached the campsite in less than the two-hour estimated time.
55mph is the speed of the motorcyclist and not velocity. There was no directional attribute.
Walking south along the two-mile canyon trail generally takes less time than traveling the same trail north because walking south is all downhill
This is not quantifiable.
The boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.
The 200m marker north is the displacement and the time is 5minutes. This is the most scientifically accurate description of velocity.
