The lens changes the focal distance of the eye so that you can focus on images/objects.

Answer:

The lens is located in the eye. By changing its shape/curvature, the lens changes the focal distance of the eye. In other words, it focuses the light rays by changing its curvature and let light pass through it in order to create clear images of objects . It also works together with the cornea to refract, or bend, light.

mr_godi [17]

Answer:

Acceleration is 1.2 m/s^2.

Explanation:

initial velocity, u = 0

distance, d = 60 m

time, t = 10 s

Let the acceleration is a.

use second equation of motion

$s= u t +0.5 at^2\\\\60 = 0 + 0.5 \times a \times 10\times 10\\\\a = 1.2 m/s^2$

Now according to the Newton's second law

Force = mass x acceleration

Let the mass is m.

F = m x 1.2 = 1.2 m Newton

Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are differen

masya89 [10]

A parallel circuit has multiple paths from the energy source to the resistors (e.x., lightbulbs). If one bulb was to burn out, the rest would stay on, unlike a series circuit. If one bulb was to burn out, the circuit is no longer fully connected because there is only one path from the energy source to the resistors. But, despite these differences, they are similar in the way that they do have paths from the energy source to the resistors.

Estimate the peak wavelength for radiation from ice at 273 k.

Andrews [41]

<h2>Answer: 10615 nm</h2>

Explanation:

This problem can be solved by the Wien's displacement law, which relates the wavelength $\lambda_{p}$ where the intensity of the radiation is maximum (also called peak wavelength) with the temperature $T$ of the black body.

In other words:

There is an inverse relationship between the wavelength at which the emission peak of a blackbody occurs and its temperature.

Being this expresed as:

$\lambda_{p}.T=C$ (1)

Where:

$T$ is in Kelvin (K)

$\lambda_{p}$ is the wavelength of the emission peak in meters (m).

$C$ is the Wien constant, whose value is $2.898(10)^{-3}m.K$

From this we can deduce that the higher the black body temperature, the shorter the maximum wavelength of emission will be.

Now, let's apply equation (1), finding $\lambda_{p}$ :

$\lambda_{p}=\frac{C}{T}$ (2)

$\lambda_{p}=\frac{2.898(10)^{-3}m.K}{273K}$

Finally:

$\lambda_{p}=10615(10)^{-9}m=10615nm$ This is the peak wavelength for radiation from ice at 273 K, and corresponds to the infrared.

Why is declaring faith the first of the five pillars of Islam?

Pie

The philosophy is simple that no one can start the journey towards being a Muslim unless he professes the basic principles mentioned in the "Declaration of Faith", which is "“There is none worthy of worship but Allah and Muhammad is His Messenger”.
The declaration consists of the two most fundamental elements of Islamic ideology:
1) Unity of Allah: Declaring that there is only One God and none else is mandatory to be a Muslim.
2) Faith in the prophet hood of Muhammad, the messenger of Islam.
