Explanation:
Distance d=1.5×108 km=1.5×1011 m
Mass of the sun, m=2×1030 kg
Mass of the earth, M=6×1024 kg
Force of gravitation, F=G×d2m×M
F=6.7×10−11×(1.5×1011)22×1030×6×1024=3.57×1022 N
Malleus, incus, and stapes, respectively, and collectively, as "middle ear ossicles<span>".</span>
Formic acid- Explanation The acid produced by ants is called formic acid. The name comes from the Latin word for ant, which is “Formica.” Chemically, it is a simple carboxylic acid. The most common species of black ant in the United States is the black carpenter ant, which delivers a small amount of formic acid through its jaws as it bites.
So the mass of water remains the same when it freezes. The mass of any substance is the same when it changes phase from liquid to gas, or solid. This is the principle of mass conservation.
