Does distance from modem affect internet speed
7nadin3 [17]
It shouldn't, but to be honest, it kind of does.
The further you are away from the modem,
the less connectivity you have.
Because you can't connect really well, your internet slows down.

So... yes?

Most of the water on Earth is
e-lub [12.9K]

Answer:

3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.

To break the numbers down, 96.5% of all the Earth's water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact.

As these charts and the data table show, the amount of water locked up in ice and snow is only about 1.7 percent of all water on Earth, but the majority of total freshwater on Earth, about 68.7 percent, is held in ice caps and glaciers. Source: Gleick, P. H., 1996: Water resources.

The earth has an abundance of water, but unfortunately, only a small percentage (about 0.3 percent), is even usable by humans. The other 99.7 percent is in the oceans, soils, icecaps, and floating in the atmosphere. Still, much of the 0.3 percent that is useable is unattainable.

I hope this answer help you.

A 67.3-kg climber is scaling the vertical wall of a mountain. His safety rope is made of a material that, when stretched, behave
Monica [59]

Answer:

d=0.59m

Explanation:

From the question we are told that:

Mass m=67.3 kg

Spring constant \mu=1.23 * 10^3 N/m

Fall Height h=0.921m

Generally the Energy theorem equation for momentum is mathematically given by

Change in KE=Work done by gravity + work done by spring

0=mg*(h + d) - \frac{\mu d^2}{2}

0=(67.3 * 9.81 (0.921 + d)) -\frac{(1.23 * 10^3 * d^2}{ 2}

0=608.1-660.213d-615d^2

Solving Quadratic equation

d=0.59m

A 2.80 kg mass is dropped from a height of 4.50 m. Find its potential energy when it reaches the ground.
marshall27 [118]

Answer:

123.48J

Explanation:

Given parameters:

Mass of the ball  = 2.8kg

Height  = 4.5m

Unknown:

Potential energy  = ?

Solution:

The potential energy is the energy due to the position of a body. It is mathematically given as;

      P.E   =  mgh

m is the mass

g is the acceleration due to gravity

h is the height

 Now insert the parameters and solve;

          P.E  = 2.8 x 4.5 x 9.8  = 123.48J

A graph titled Position versus time for with horizontal axis time (seconds) and vertical axis position (meters). A straight blue
eduard

a) starting position of this object is 3m

b) Velocity is 3m/s

Explanation:

The points identified on the blue line are; (0,3) and (4,15)

The starting position of this object is at 3m where time was 0 seconds.

The velocity of this travelling object is calculated by finding the slope of the graph.

slope=velocity=Δy/Δx

Δy=15-3=12

Δx=4-0=4

m=12/4=3

velocity is 3 m/s
