A would be the best answer to this question
Answer:
in it's natural state it's an element
-- The amplitude of Wave-1 is greater than the amplitude of Wave-2 ...
possibly 3 or 4 times as great.
-- The wavelength of Wave-1 is longer than the wavelength of Wave-2 ...
maybe almost twice as long.
-- The frequency of Wave-2 is greater than the frequency of Wave-1 ...
maybe almost twice as frequent.

If the reaction forms a new substance it's a chemical reaction.
Answer:
a) Maximum altitude of the projectile,
b) v = 10885.7 m/s
Explanation:
a) Mass of the earth,
Mass of the projectile =
Launch speed, v = 2.31 * 10³ m/s
Earth radius, r = 6.36 ✕ 10⁶ m
Workdone by the projectile against gravity
...............(1)
Kinetic energy of the projectile:
...................(2)
Equating (1) and (2) based on the law of energy conservation
b) Smallest required change in the satellite speed
Altitude, h = 352 km = 352000 m
Earth radius, r = 6.38 * 10⁶ m
v = 10885.7 m/s
