Answer:
absorbed/taken in
Explanation:
endo means internal; within.
exo means external; from outside.
Sunlight focuses at a point 18.5 cm behind the lens. As daylight comes from an indefinite distance, so it is a real image. The lenses that will focus on the parallel rays behind the lens are converging lenses.
What is a converging lens?
- A converging lens causes parallel rays of light to come to a focal point.
- A convex lens is a converging lens.
- A converging lens has a positive focal length.
- A converging lens forms a real or virtual image of a real object.

52,200m/min bro. Hope this is the right answer
Answer:
0.695s
Explanation:
From Hooke's law, the restoring force is given has
F = -ky .......1
Where F is the force, y is the spring displacement and k force constant of the spring.
Also recall,
F=mg ............ 2
Where m is the mass of object, g is the acceleration due to gravity.
Equating 1 and 2
Ky = mg
Given that g=9.8m/s2 , y is 3.4cm and g is 8g
K×3.4/100m =8/1000kg × 9.8m/s2
K= ( 0.008kg × 9.8m/s2 ) ÷ 0.034
K= 0.0784÷0.035
K=2.24N/m
Mass ofvthe second object is 25g =0.025kg
Period of oscillation T
T=2π√m/k
T=2×3.142√0.025/2.24
T=6.284√0.0111
T=0.659seconds
Explanation:
Assuming no air resistance, the horizontal acceleration at all points is 0, and the vertical acceleration at all points is -g (if near the surface of the Earth, -9.8 m/s²).
