Answer:</h2><h2>B. Their valence shells are full of electrons.</h2>
Answer:
Input work is the work done on a machine as the input force acts through the input distance. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance.Jan 15, 2020

You wouldn't know it from reading the question,
but the volume of a sphere is
4/3 π (radius)³ .
So the volume of Saturn is
(4/3 π) (6.03 x 10⁷ m)³ = about 9.184 x 10²³ m³
and its density is (mass) / (volume)
= (5.68 x 10²⁶ kg) / (9.184 x 10²³ m³)
Sadly, we need this to be in units of ' gram/cm³ ' so we need to
account for some conversion of units.
= (5.68 x 10²⁶ kg) · (1,000 g/kg) / (9.184 x 10²³ m³) · (10⁶ cm³/m³)
= (5.68 x 10²⁹ grams) / (9.184 x 10²⁹ cm³)
= 0.618 gram/cm³ .
Look at that !
The density of the planet Saturn is less than ' 1 '.
If you had a big enough bathtub full of water, Saturn would float in it !
The surface area of a sphere is
4 π (radius)²
= (4 π) (6.03 x 10⁷ m)²
= (4 π) (36.4 x 10¹⁴ m²)
= 4.57 x 10¹⁶ m²
Answer:
165.11 K Pa
Explanation:
Applying Bernoulli theorem ,the problem which deals with the conservation of energy of a flowing fluid , we have
P + 1/2ρ v² + ρgh = constant
P represents pressure , ρ represents density of liquid flowing v is velocity, h is the height from the ground.
P₁ + 1/2ρ v₁² + ρgh₁ =P₂ + 1/2ρ v₂² + ρgh₂
Substituting the values we get
46.4 x 10³ + .5 x 1000 x (4.37)²+ρg( h₁ - h₂) = P₂ + .5 X 1000x(4.37/4)²
46400+ 9548.45 +1000x 9.8 x 11.2 = P₂ +596.78
P₂ = 165.11 K Pa
