Answer:
The instrument is a microscope
Explanation:
the length of a given instrument is 14cm which is more than the sum of the focal length (0.6 + 4.5) = 5.1cm
however. the length of microscope is more than the sum of focal length of objective and eye pieces
The statements that best describe solstices include:
A. They occur when the Sun reaches its highest or lowest point in the sky.
B. They affect the amount of sunlight in the Northern Hemisphere in June.
D. They influence the cycling of different seasons based on the Sun's height in the sky.
A solstice can be defined as a phenomenon in which the Sun reaches its maximum or minimum declination relative to the celestial equator on the celestial sphere, thereby, producing either the least amount of daylight time within a day or the most amount of daylight time. Also, it occurs twice in a year between June 20-22 and December 21-23.
Traditionally, solstice marks the beginning (start) of seasons such as summer and winter depending on the hemisphere.
Hence, the statements that best describe solstices include:
- Solstices occur when the Sun reaches its highest (maximum) or lowest (minimum) point in the sky.
- Solstices affect the amount of daylight time (sunlight) in the Northern Hemisphere in June.
- Solstices influence the cycling of different seasons depending on the Sun's height in the sky.

Answer:
Explanation:
Area of electrodes, A = 2 cm x 2 cm = 4 cm²
Separation between electrodes, d = 1 mm
Voltage, V = 9 V
(a)
Let C is the capacitance between the electrodes
C = 3.54 x 10^-12 F
Let q be the charge on each of the electrode
q = C x V
q = 3.54 x 10^-12 x 9 = 3.2 x 10^-11 C
(b)
As, the battery is disconnected the charge on the electrodes remains same.
(c)
As the battery is connected the voltage is same.
capacitance is change.
As the distance is doubled, the capacitance becomes half and the charge is also halved. q' = q/2 = 1.6 x 10^-11 C
Precision because it’s the answer
A grandfather paradox is a situation where individual travels to the past and then introduces a change which affects or contradicts the present.
<h3>What is a grandfather paradox?</h3>
A paradox is a situation or statement which involves two contradictions.
A grandfather paradox is a situation which is defined by the ability of an individual to travel to a time in the past usually before the birth of their grandfather and then introduces a change which affects or contradicts the present. For example, killing the grandfather to prevent their birth.
In conclusion, a grandfather paradox is is an event which contradicts the present as a result of a change done to the past.
