Answer:
Explanation:
Thinking process:
Let:
distance = speed × time
for the hare:
for the tortoise:
Let the length of the shell be s. Then the two are related. So:
Let's say the hare ran at x times the speed of the tortoise:
So, the equation still holds :
The image would be 53 cm from the lens of your eye.
What is Lens?
A lens is a transmissive optical tool that uses refraction to focus or disperse a light beam. A compound lens is made up of multiple simple lenses (elements), typically arranged along a common axis, as opposed to a simple lens, which is one solid piece of transparent material. Glass or plastic are used to make lenses, which are then polished or moulded into the desired shape. In contrast to a prism, which simply refracts light without focusing it, a lens can focus light to create an image. Lenses are also devices that focus or disperse waves as well as radiation other than visible light, such as <u>explosive lenses, microwave lenses, particle lenses, and acoustic lenses</u>.
Lenses are a common component of <u>telescopes</u><u>, binoculars, and cameras, among other imaging devices</u>.

Answer: 180N/m(to 2 significant figures)
Explanation:
According to hooked law which states that the extension of a material is directly proportional to the applied force provided that the elastic limit is not exceeded. Mathematically, F = ke where;
F is the applied force in newtons
k is the elastic/spring constant in N/m
e is the extension in meters
Given applied force = 35N
extension = 20cm = 0.2m
Since F = ke,
k = F/e = 35/0.2
k = 175N/m
The spring constant is 175N/m
= 180N/m (to 2significant figures)
A < B < C
C will increase faster than B which is faster than A
