Answer:
Explanation:
we know that for ideal gag we have
pV =nRT
Since volume, gas constant R and T are constant, so we have
n = 0.289 mole
hence mass removed
Do EM Waves need matter in order for them to go from one place to another?

The kinetic energy of an object is given by:
where
K is the kinetic energy
m is the mass of the object
v is its velocity.
The comet in our problem has a mass of
and a velocity of 
, so its kinetic energy is:
where
K is the kinetic energy
m is the mass of the object
v is its velocity.
The comet in our problem has a mass of
Heya!!
For calculate aceleration, let's applicate second law of Newton:
⇒ Being:
→ F = Force = 12 N
→ m = Mass = 3 kg
→ a = aceleration = ?
Lets replace according formula and leave the "a" alone:
Result:
The aceleration of the object is of <u>4 m/s²</u>
