Do you think it is okay to make friends over the internet or is it too dangerous to trust what people over the internet are sayi
Lemur [1.5K]
I think it’s kind of ok only if they tell us sensible things. For example we might have some problems but we feel embarrassed to tell someone who we know so we want good advice from someone who doesn’t know me and can’t judge me based on anything other than my story and reasons. But if someone tells me we should you should refuse and if they start bothering you then you should tell an adult. Hope this helps!!!

Suppose y varies directly with x, and y =24 when x=8. what is the value of y when x=10?
arlik [135]
The value of y when x is equal to 10 is 30. This is because for every value of x the value of y is 3. This can be known if you divide 24 by 8 you get 3. So if x=10 then y would equal 30.

What is the ratio of the intensities of an earthquake PP wave passing through the Earth and detected at two points 19 kmkm and 4
Tamiku [17]

Answer:

The ratio of the intensities is roughly 6:1.  

Step-by-step explanation:

The intensity I() of an earthquake wave is given by:

I = \frac{P}{4\pi d^{2}}

<em>where P: is the power ans d: is the distance. </em>

Hence, the ratio of the intensities of an earthquake wave passing through the Earth and detected at two points 19 km and 46 km from the source is:

\frac{I_{1}}{I_{2}} = \frac{P/4\pi d_{1}^{2}}{P/4\pi d_{2}^{2}}

<em>where I₁ = P/4πd₁², d₁=19 km, I₁ = P/4πd₂² and d₂=46 km     </em>

\frac{I_{1}}{I_{2}} = \frac{d_{2}^{2}}{d_{1}^{2}}

\frac{I_{1}}{I_{2}} = \frac{46 km^{2}}{19 km^{2}}

\frac{I_{1}}{I_{2}} = 5.9:1

Therefore, the ratio of the intensities is roughly 6:1.  

 

I hope it helps you!
