A. All natural radiation is at a level low enough to be safe
Answer:
Avogadro's law.
Explanation:
Avogadro’s law states that, equal volumes of all gases at the same temperature and pressure contain the same number of molecules.
Mathematically,
V n
V = Kn where V = volume in cm3, dm3, ml or L; n = number of moles of gas;
K = mathematical constant.
The ideal gas equation is a combination of Boyle's law, Charles' law and Avogadro’s law.
V 1/P at constant temperature (Boyle’s law)
V T at constant pressure ( Charles’law)
V n at constant temperature and pressure ( Avogadro’s law )
Combining the equations yields,
V nT/P
Introducing a constant,
V = nRT/P
PV = nRT
Where P = pressure in atm, Pa, torr, mmHg or Nm-2; V = volume in cm3, dm3, ml or L; T = temperature in Kelvin; n = number of moles of gas in mol; R = molar gas constant = 0.082 dm3atmK-1mol-1
volume of milk is given as
we will convert it into mL unit
mass of the milk m = 2kg
m = 2000 g
now for the density we can use
<em>so the density is 0.264 g/mL for above sample</em>
Answer:
Explanation:
If a force of 20N is situated at 30° south west, the x and y component of the vector will be expressed as:
Fx = -Fcos 30° and Fy = -Fsin30°
They are but negative because the force acts in the third quadrant of a four cardinal point
Fx = -20cos30°
Fx = -20(√3/2)
Fx = -10√3N
Hence the -x component if the force is -10√3N
Fy = -20sin30°
Fy = -20(1/2)
Fy = -10N
Hence the y-component is the vector is -10N
Explanation:
it dosent depend on the weights of the items. I'll reach the ground at same time taking as no air friction or restrictions.
i.e
v = u + gt
whte v is final velocity of the object
u is initial velocity of the object
g is acceleration due to gravity and
t is time. thanks
please if found helpful rate brainliest
