- The cube will float on top of corn syrup
- Floats in water
- Floats in motor oil
- will sink to the bottom below gasoline
Explanation:
The crux of the problem is if the density of the cube would be greater than either of the liquid , it would sink else it will float.
Given data-
Side of the cube- 2cm
Mass= 6.71gm
We know that volume of the cube= side³
Hence volume of cube= 8 cm
³
Density= mass/volume
Hence Density of the cube- 6.71/8= 0.84g/cm³ or 0.84 gm/mL
Now comparing the density of cube with other liquid-
A.) float on corn syrup- Since the density of corn syrup (1.40 gm/ mL) is much greater than cube (0.84 gm/ mL), hence it would float atop the syrup.
B.) Floats in corn syrup- The cube would float on the corn syrup.
C.) Float in water- The cube would float in water since its density (0.84 gm/mL) is less than water (1 gm/mL)
D.) Float in motor oil- It would float in motor oil along the surface since the density is nearly same (0.90 gm/mL)
E.) Float in alcohol- It would sink in alcohol due to greater density(0.80 gm/ mL).
F.) Float in gasoline- It would sink in gasoline since its density is more than that of gasoline (0.67 gm/ mL).
G.) sink at bottom in gasoline- It would sink in gasoline since its density is more than that of gasoline (0.67 gm/ mL).
Answer:
V = 42187 m/s = 42.18 km/s
Explanation:
given data:
mass of sun is
radius of earth orbit is
minimum speed can be determined by using following formula
}
where G is
Plugging all value to get desired value
V = 42187 m/s = 42.18 km/s
Answer:
29274.93096 m/s
Explanation:
= Distance at perihelion =
= Distance at aphelion =
= Velocity at perihelion =
= Velocity at aphelion
m = Mass of the Earth = 5.98 × 10²⁴ kg
M = Mass of Sun =
Here, the angular momentum is conserved
Earth's orbital speed at aphelion is 29274.93096 m/s
Kinetic energy is given by
Kinetic energy at perihelion is
Potential energy is given by
Potential energy at perihelion is
Kinetic energy at aphelion is
Potential energy is given by
Potential energy at aphelion is
Answer:
Iris
Explanation:
The pupil is where the light enters the eye, however, the iris is pupil tissue and is the one who regulates the amount of light that it lets through.
The iris opens or closes to allow a greater or lesser flow of light through the pupil.
In summary, the iris is responsible for regulating the amount of light that enters the eye.
