Answer:
Option C is correct
Explanation:
A supersaturated solution is one that has more solute dissolved than the solution should hold at that temperature.
Examples include carbonated water, sugar syrup, honey.
A solution of a chemical compound can be dissolved in heated water to prepare a supersaturated solution. A solution becomes supersaturated as its temperature is changed.
1 meter = 1e9 nm
To get meters, divide nanometers by 1e9:
9.95nm / 1x10^9 = 9.95x10^-9 meters
Answer: 9.95e-9 meters
Answer:
Object A
Explanation:
given,
Object A
mass,m₁ = 1.4 Kg
speed of the car,v₁ = 14.2 m/s
object B
mass,m₂ = 2 Kg
speed,v₂ = 5 m/s
Kinetic energy of the object will be absorbed by you when it hit you.
KE₁ = 141.148 J
kinetic energy of the object B
KE₂ = 25 J
Hence, the Object A will feel worse if hit you because of the kinetic energy of the object A is more.
I think this answer Yes, salt is the crystal we use to season our food. But in chemistry, salt is a term used to describe a compound made by joining a positively charged acid with a negatively charged base. Table salt is the compound sodium chloride. It's composed of a positively charged sodium atom and a negatively charged chloride atom.
Answer:
47.0 N
Explanation:
First of all, let's convert the distance of the rocket from the Sun from AU to metres:
The force of gravity acting between the Sun and the rocket is:
where
is the gravitational constant
is the mass of the Sun
m = 4500 kg is the mass of the rocket
r is the distance between the Sun and the rocket
Substituting into the equation,
