the most common first sign of lung cancer is a constant cough. there could also be coughing up blood or reddish colored spit, and chest pain when you laugh, cough, and breathe.

So, my Nana had lung cancer and she just recently passed away from it because they could not find her a new lungs for a transplant. Signs aren't typically noticeable or seem severe until you get tested and realize you have lung cancer. Some signs would be a new cough that doesn't go away and maybe even have a very heavy chest, shortness of breath, or coughing up blood sputum (spit or phlegm) A lot of the "symptoms" could be similar to a cold or even asthma. I would say if you don't have asthma or asthma history it would be good to go to the doctor to get it checked out. Like I said they are all very similar to a cold or something like that but should be checked out if continuous.

I hope this helps :)

The force applied to lift the crate is 171 N

Explanation:

The lever works on the principle of equilibrium of moments, so we can write:

$F_i d_i = F_o d_o$

where

$F_i$ is the force in input

$d_i$ is the arm of the input force

$F_o$ is the output force

$d_o$ is the arm of the output force

For the lever in this problem, we have:

$d_i = 0.25 m$

$d_o = 0.19 m$

$F_i = 130 N$ (force applied)

Solving the equation for $F_o$ , we find the force applied to lift the crate:

$F_o = \frac{F_i d_i}{d_o}=\frac{(130)(0.25)}{0.19}=171 N$

I Need help with this problem i don’t know what to do

Mazyrski [523]

Answer:

The density of the sample is 36 g/cm³

Explanation:

m= 972g

l=3cm

V = l³ = 3³ = 27 cm³

density = mass/volume

= 972/27

= 36 g/cm³

Which does not describe the relationship between the nucleus and the electron cloud of an atom?

Margaret [11]

Choices 'a', 'c', and 'd' are true.

In choice 'b', I'm not sure what it means when it says that masses
are 'balanced'. To me, masses are only balanced when they're on
a see-saw, or on opposite ends of a rope that goes over a pulley.

Maybe the statement means that the mass of the nucleus and the
mass of the electron cloud are equal. This is way false. It takes
more than 1,800 electrons to make the mass of ONE proton or
neutron, and the most complex atom in nature only has 92 electrons
in it. So there's no way that the masses of the nucleus and the electrons
in one atom could ever be anywhere near equal.

Why are we not able to see immediate after we enter a dark hall from a lighter place.

Kipish [7]

Technically this is a Biology question;

The 'amount' we can see depends on how much light can get through our pupil to hit our retina.
When there is a lot of light the pupil is small; it doesn't need to be big to let a lot of light in.
When we move to a dark space there is much less light, so the pupil 'dilates' to let enough light so we can see properly.
The period in which one cant see is simply when the pupil hasn't had time to change shape yet so doesn't let in enough light.<span />

While performing an experiment, the student creating the data table is not sure if a measurement from the experiment is a vector

marin [14]

Before coming into conclusion first we have to understand both scalar and vector .

A scalar quantity is a physical quantity which has only magnitude for it's complete specification.

A vector quantity is that physical quantity which not only requires magnitude but also possesses direction for it's complete specification.

So the most important factor that differentiate vector from scalar is the direction.

As per the question the student is doing an experiment where he is recording the data obtained during the process.

In order to arrange them in data table, he should ask about the direction of the quantity under consideration.

Hence the correct option is the third option(C)i.e does the measurement include direction?
