Answer:
1.54 m/s²
Explanation:
The free-fall acceleration is calculated as
g = w²r
Where w is the angular velocity of the satellite and r is the radius of the moon.
The angular velocity can be calculated as
Where T is the period, so
T = 110 min = 110 x 60 s = 6600 s
Then,
Finally, the radius of the moon is r = 1.7 x 10⁶ m, so the free-fall acceleration is
Therefore, the answer is 1.54 m/s²
Explanation:
during the daytime the land gets hot and the hot air blows up to the sky and to feel the space the cool you are from the Sea blows to the land this phenomenon is called sea breeze similarly at night the hot air of sea goes up n cool air from land blows to sea which is called land breexe

d. 110 grams
Explanation:
The number of grams needed to make 1molar solution from 1liter volume is 110grams.
Concentration is the number of moles of solute dissolved in a given volume of solvent.
Since:
desired concentration = 1M
volume = 1L
Number of moles = ?
Concentration =
Number of moles = concentration x volume
Number of moles = 1 x 1 = 1mole
Mass of CaCl₂ = number of moles x molar mass
Molar mass CaCl₂ = 40 + (35x 2 ) = 110g/mol
