Answer:
The focal length for given convex lens = 0.0714 m
Explanation:
Given data
Radius () = 12.5 cm
Radius () = 16.7 cm
Since the radius of curvature is positive so these are the convex lens.
Now focal length is given by
⇒ = +
⇒ Put the values of and in the above formula we get,
⇒ = +
⇒ = 0.13988
⇒ f =
⇒ f = 7.14 cm
⇒ f = 0.0714 m
Thus the focal length for given convex lens = 0.0714 m
Answer:
a). Roger travel total a distance of 2070m
b). The average speed of the whole tip 0.16025
Explanation:
a).
First trip 450m
Second trip :
So final distance is
450m+1620m=2070m
b).
The average speed is 0.10625
Answer:
The level of the root beer is dropping at a rate of 0.08603 cm/s.
Explanation:
The volume of the cone is :
Where, V is the volume of the cone
r is the radius of the cone
h is the height of the cone
The ratio of the radius and the height remains constant in overall the cone.
Thus, given that, r = d / 2 = 10 / 2 cm = 5 cm
h = 13 cm
r / h = 5 / 13
r = {5 / 13} h
Also differentiating the expression of volume w.r.t. time as:
Given: = -4 cm³/sec (negative sign to show leaving)
h = 10 cm
So,
<u>The level of the root beer is dropping at a rate of 0.08603 cm/s.</u>
