<span>Hydrothermal mineral deposit, any concentration of metallic minerals formed by the precipitation of solids from hot mineral-laden water. The solutions are thought to arise in most cases from the action of deeply circulating water heated by magma.</span>

an object is placed 20cm from a converging lens. If the real image is formed 80cm from the object, what is the focal length of t

masya89 [10]

Explanation:

Here,

object distance(u)=20cm

image distance(v)=80cm-20cm=60cm

focal length(f)=?

we know ,

(1/f)=(1/v)+(1/u)

1/f = 1/60 + 1/20

1/f = (1+3)/60

60 =4f

f=15cm

A person who weighs 685 N steps onto a spring scale in the bathroom, and the spring compresses by 0.88 cm. (a) What is the sprin

kotykmax [81]

To solve this problem it is necessary to use the concepts of Force of a spring through Hooke's law, therefore,

$F = kx$

Where,

k = Spring constant

x = Displacement

Initially our values are given,

$F = 685N$

$x = 0.88 cm$

PART A ) With this values we can calculate the spring constant rearranging the previous equation,

$k = \frac{F}{x}$

$k = \frac{685}{0.88*10^-2}$

$k = 77840.9N/m$

PART B) Since the constant is unique to the spring, we can now calculate the force through the new elongation (0.38cm), that is

$F = kx$

$F = (77840.9)(0.0038)$

$F = 295.79N$

Therefore the weight of another person is 265.79N.
