Answer:
b) to produce electrical charges;
Explanation:
Electrical generators are used in a circuit to produce electrical charges. The flow of these charges actually produces electrical energy in a circuit which is needed and essential to power devices and gadgets.
A generator uses mechanical energy through the movement of its parts to produce electrical energy. The flow of electrons streams produces the electrical energy which helps to produce power.
A generator works on the basis of electromagnetic induction using the movement of electric charges.
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:
T = 273 + (-50) = 273 – 50 = 223 K
R = 188.82 J / kg K for CO2
Density (Martian Atmosphere) = P / RT = 900 / 188.92 x 223 = 900 / 42129.16 = 0.0213 kg /
T = 273 +18 = 291 K, R = 287 J / kg k (for air) P = 101.6 k Pa = 101600 Pa
Density (Earth Atmosphere) = P / RT = 101600 / 287 x 291 = 1.216 kg /
Well other planets have a gravitational pull that's what keep the planet's orbiting the sun. But the amount of gravity differs by mass.
Hope this helps :)
