Answer

The same number of particles in a gas spread further apart than in the liquid or solid states.

Explanation:

The same number of particles in a gas spread further apart than in the liquid or solid states. The same mass takes up a bigger volume. This means the gas is less dense. Density also depends on the material.

We are sending a 30 Mbit file from source host A to destination host B. All links in the path between source and destination hav
Dmitrij [34]

Answer:

t=1.5\times 10^{-4}\ s

Explanation:

Given:

  • file size to be transmitted, D=30\ Mb
  • transmission rate of data, \dot D=10\ Mb.s^{-1}
  • propagation speed, v=2\times 10^8\ m.s^{-1}
  • distance of data transfer, s=10000\ km=10^4\ m

<u>Now the delay in data transfer from source to destination for each 10 Mb:</u>

t'=\frac{s}{v}

t'=\frac{10^4}{2\times 10^8}

t'=5\times 10^{-5}\ s

<u>Now this time is taken for each 10 Mb of data transfer and we have 30 Mb to transfer:</u>

So,

t=3\times t'

t=3\times 5\times 10^{-5}

t=1.5\times 10^{-4}\ s

After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 55.0 cmcm. She finds that the pen
Art [367]

Hi there!

First, let's find the period of the pendulum. This can be found by solving for the amount of time it takes for the pendulum to make ONE complete swing.

T = \frac{\text{Total time}}{\text{Number of complete swings} }\\\\T = \frac{145}{110} = 1.318 s

Now, let's use the equation for the period of a simple pendulum:
T = 2\pi \sqrt{\frac{L}{g}}

T = Period (1.318 s)
L = length of string (0.55 m)

g = acceleration due to gravity on planet (? m/s²)

Let's solve for 'g' doing some quick rearranging of the equation:
T^2 = 4 \pi^2 (\frac{L}{g})\\\\g = \frac{4\pi^2 L}{T^2}\\\\

Solving for 'g' by plugging in values:
g = \frac{4\pi^2 (0.55)}{(1.318)^2}\\ \\= \boxed{12.496 \frac{m}{s^2}}
