Answer:
The focal length of the lens is 34.047 cm
The power of the needed corrective lens is 2.937 diopter.
Explanation:
Distance of the object from the lens,u = 26 cm
Distance of the image from the lens ,v= -110 cm
(Image is forming on the other side of the lens)
Since ,lens of the human eye is converging lens,convex lens.
Using a lens formula:
f = 34.047 cm = 0.3404 m
Power of the lens = P
Let FAB, be the force exerted on body B by body A and FBA be the force exerted by body B on A. Suppose that due to these forces FAB and FBA, dp1/dt and dp2/dt be the rate of the change of momentum of these bodies respectively.
Answer:
Energy
A wave is a disturbance that carries energy from one place to another through matter and space.
Explanation:
A wave can be defined as a form of disturbance that carries energy from one place to another through matter and space.
The energy of wave depends on the frequency of the wave and the wavelength (lambda) of that particular wave.
Mathematically,
V = f × lambda
Answer:
Object 1.
Explanation:
Given that,
Force applied = 100 N
The spring constant of object 1 = 100 N/m
The spring constant of object 2 = 200 N/m
Using Hooke's law, we find the force applied on the object to stretch.
For object 1,
F₁ = k₁x₁
For object 2,
F₂ = k₂x₂
Object 1 stretches 1 m and object 2 stretches 0.5 m. Hence, object 1 stretches furthur.
