Which statement supports Newton's first law of motion?
O Planets can change the direction of their own orbital path.
0 Planets with more inertia will not be impacted by the Sun's gravity.
Planets can move at a varying speed due to forces exerted in space.
Planets with a greater mass will orbit more quickly than smaller planets.

h let me think

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
