The speed of light in a vacuum is 300,000,000 m/s
That is three hundred million meters per second.
Therefore, the answer is
C) millions of meters per second
The plant that is closest to the sun is murcury. Then it is venus, then earth, and then mars. Then it is jupiter, then saturn, then uranus, then neptune.
Answer:
Therefore, the distance between object and image is given by the distance between object and mirror + distance between mirror and image = 0.5 m + 0.5 m = 1 m. 4. You are provided with a concave mirror, a convex mirror, a concave lens and a convex lens. To obtain an enlarged image of an object you can use either (a) concave mirror or convex mirror.

Answer : The molar heat of solution for the salt is 452.9 kJ/mole
Explanation :
First we have to calculate the heat of solution.
where,
q = heat of solution = ?
c = specific heat of water = specific heat of solution =
m = mass of solution = 107.093 g
- Mass of solution = Mass of water + Mass of salt
- Mass of solution = 100.000 g + 7.093 g = 107.093 g
= change in temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the molar heat of solution for the salt, in kJ/mol.
where,
= molar heat of solution = ?
q = heat required = 8.456 kJ
m = mass of salt = 7.093 g
Molar mass of salt = 379.984 g/mol
Therefore, the molar heat of solution for the salt is 452.9 kJ/mole
