Radio waves are the only type of electromagnetic wave that is a transverse wave.

Uranus and neptune have methane clouds but jupiter and saturn do not. Which factor explains why?.

mr Goodwill [35]

Answer:

Temperature on Jupiter and Saturn are too high for methane to condense.

Explanation:

However, methane can condense on Uranus and Neptune because they are farther from the sun and hence colder.

In a physics lab, light with a wavelength of 570 travels in air from a laser to a photocell in a time of 16.5 . When a slab of g

aliina [53]

Answer:

Wavelength is calculated as 213.9 nm

Solution:

As per the question:

Wavelength of light = 570 nm

Time, t = 16.5 ns

Thickness of glass slab, d = 0.865 ns

Time taken to travel from laser to the photocell, t' = 21.3

Speed of light in vacuum, c = $3\times 10^{8}\ m/s$

Now,

To calculate the wavelength of light inside the glass:

After the insertion of the glass slab into the beam, the extra time taken by light to cover a thickness t = 0.865 m is:

t' - t = 21.3 - 16.5 = 4.8 ns

Thus

$\frac{d}{\frac{c}{n}} - \frac{d}{v} = 4.8\times 10^{- 9}$

$\frac{0.8656}{\frac{c}{n}} - \frac{0.865}{v} = 4.8\times 10^{- 9}$

where

n = refractive index of the medium

v = speed of light in medium

$\frac{0.8656}{\frac{c}{n}} - \frac{0.865}{v} = 4.8\times 10^{- 9}$

$n = \frac{4.8\times 10^{- 9}\times 3.00\times 10^{8}}{0.865} + 1$

n = 2.66

Now,

The wavelength in the glass:

$\lambda' = \frac{\lambda }{n}$

$\lambda' = \frac{570}{2.66} = 213.9\ nm$

A girl delivering newspapers covers her route by traveling 3.00 blocks west, 4.00 blocks north, and then 6.00 blocks east. What

Harrizon [31]

The concepts used to solve this problem are those related to the Pythagorean theorem for which we will calculate the distance and the pitch.

According to the attached diagram we have that the expression of the resulting displacement is

$R = \sqrt{(3b)^2+(4b)^2}$

Therefore the resultant displacement of the girl is

$R = \sqrt{(9b^2+16b^2)}$

$R = \sqrt{25b^2}$

$R = 5b$

Therefore the girl has displaced around of 5 blocks

An object located near the surface of Earth has a weight of a 245 N

marusya05 [52]

Answer:

The mass of the object is 24.5 kg and weight of the object on Mars is 91.14 N.

Explanation:

Weight of the object on the surface of Earth, W = 245 N

On the surface of Earth, acceleration due to gravity, g = 10 m/s²

Weight of an object is given by :

W = mg

m is mass

$m=\dfrac{W}{g}\\\\m=\dfrac{245\ N}{10\ m/s^2}\\\\=24.5\ kg$

So, the mass of the object is 24.5 kg

Acceleration due to gravity on Mars, g' = 3.72 m/s²

Weight of the object on Mars,

W' =mg'

W' = 24.5 kg × 3.72 m/s²

= 91.14 N

So, the weight of the object on Mars is 91.14 N.
