Gamma rays are unlike alpha and beta particles because gamma rays:
are more strongly deflected by electric or magnetic fields
have less energy than either alpha or beta particles
have more mass than either alpha or beta particles
have no effect on atomic number or mass number of the atoms that emit them

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
