Answer:

Geographers explore both the physical properties of Earth's surface and the human societies spread across it. They also examine how human culture interacts with the natural environment, and the way that locations and places can have an impact on people.

A raft is made using a number of logs (TBD) with 25-cm diameter and 2-m-length. It is desired that a maximum 90 percent volume o

Vilka [71]

Answer:

6logs

Explanation:f

First finding the volume of the logs

V= π/4d²l

= 0.098m³

So number of logs will be

Weight of 2 boys + weight of log = buoyancy force.

2( 400)+ N ( Mlog x g) = density of water x volume displaced x g

2(400) = N x 0.098x 1000x 9.8 x 0.9- 0.75* 1000

N= 5.5 which is approx 6logs

According to coulombs law, what will happen to the force between two charged particles if the magnitude are increased by 6 times

seropon [69]

Answer: The electrostatic force will be the same

Explanation:

According to Coulomb's Law, when two electrically charged bodies come closer, appears a force that attracts or repels them, depending on the sign of the charges of this two bodies or particles.

In this sense, this law states the following:

"The electrostatic force $F_{E}$ between two point charges $q_{1}$ and $q_{2}$ is proportional to the product of the charges and inversely proportional to the square of the distance $d$ that separates them, and has the direction of the line that joins them"

$F_{E}= K\frac{q_{1}.q_{2}}{d^{2}}$ (1)

Being $K$ is a proportionality constant.

Now, if each $q_{1}$ and $q_{2}$ are increased by 6, and the distance between them as well, we will have the following:

$F_{E}= K\frac{6 q_{1}. 6 q_{2}}{(6d)^{2}}$ (2)

$F_{E}= 36 K\frac{q_{1}. q_{2}}{36d^{2}}$ (3)

Simplifying:

$F_{E}= K\frac{q_{1}.q_{2}}{d^{2}}$ (4)

Comparing (1) with (4) we can see the electrostatic force is the same.

A car manufacturer claims an enginerring breakthrough, since it successfully reduced its interior noise level from 65dB to 55 dB

Stells [14]

Yes, that is truly amazing.

They significantly reduced the noise's intensity by 90%, that might be proper reaction.

<h3>What is noise?</h3>

Unwanted sound that is regarded loud, unpleasant, or disruptive to hearing is called noise.
Physically speaking, there is no difference between unwanted sound and desired sound because both are vibrations traveling through a medium like air or water.
When the brain receives and interprets a sound, a difference occurs.
Decibels are used to measure sound (dB).
A motorcycle engine operating is roughly 95 dB louder than regular conversation, which is around 60 dB louder than a whisper.
Your hearing may begin to be harmed if exposed to noise over 70 dB for an extended period of time.
Your ears can suffer instant damage from loud noise above 120 dB.

<h3>What is sound intensity?</h3>

The power carried by sound waves per unit area in a direction perpendicular to that region is known as sound intensity or acoustic intensity.
The watt per square meter is the SI measure of intensity, which also covers sound intensity.
