To solve this problem, we will get f and then we will use it to calculate the power.
So, for this farsighted person,
do = 25 cm and di = -80
Therefore:
1/f = (1/25) + (1/-80) = 0.00275 = 0.275 m
Power = 1/f = 1/0.275 = +3.6363 Diopeters.
This means that the lens is converging.
Answer:
The micturition reflex can be voluntarily controlled by the relaxation of the external urethral sphincter.
Answer: Option (C) is the correct answer.
Explanation:
When we heat a fluid then the movement within the fluid makes hot (less dense) material to rise and cooler (more denser) material to sink at the bottom. This process is known as convection.
Thus, in the diagram hot (less dense) water will rise and cooler (more dense) water sinks at the bottom.
Therefore, we can conclude that according to the arrow the label belongs to cooler water sinks.
Answer:
They diverge on refraction
Explanation:
When parallel light rays strike a concave lens, they will diverge that is they spread out .
Concave lens is also known as diverging lens, which means that when parallel rays of light strike on it, the lens spreads out the light rays ( that is it diverges the rays of light) that are refracted through it.
At the middle of concave lens is thinner.
When light is passes through the lens they diverge it or spread out.
The concave lens causes light rays to bend away or diverge from its axis since the concave lens is a diverging lens.
