Answer:
Explanation:
Both carts are modelled by using the Principle of Energy Conservation and Work-Energy Theorem:
Cart A:
By assuming a constant acceleration, final velocity is equal to:
Then,
Cart B:
By assuming a constant acceleration, final velocity is equal to:
The kinetic energy of cart B is 0.5K.
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:
y = 1.75 cm
Explanation:
In the double-slit experiment the equation for destructive interference is
d sin tea = (m + ½)
λ
let's use trigonometry to find the angle
tan θ = y / L
as all the experiment does not occur at small angles
tan θ = sin θ / cos θ = sin θ = y / L
we substitute
y = (m + 1/2 ) λ L / d
we calculate
y = (3 + ½) 500 10⁻⁹ 5.00 / 0.5 10⁻³
y = 1.75 10⁻² m
y = 1.75 cm
It would be 50000000 in mL
