Answer:
The terminal velocity is
Explanation:
From the question we are told that
The mass of the squirrel is
The surface area is
The height of fall is h =4.8 m
The length of the prism is
The width of the prism is
The terminal velocity is mathematically represented as
Where is the density of a rectangular prism with a constant values of
is the drag coefficient for a horizontal skydiver with a value = 1
A is the area of the prism the squirrel is assumed to be which is mathematically represented as
substituting values
Answer:
distance between the dime and the mirror, u = 0.30 m
Given:
Radius of curvature, r = 0.40 m
magnification, m = - 2 (since,inverted image)
Solution:
Focal length is half the radius of curvature, f =
f =
Now,
m = -
- 2 = -
= 2 (2)
Now, by lens maker formula:
v = (3)
From eqn (2):
v = 2u
put v = 2u in eqn (3):
2u =
2 =
2(u - 0.20) = 0.20
u = 0.30 m
