An airplane moving towards the west travels 275 km in 30 minutes. Which option correctly identifies the speed and velocity of the airplane?
o
Speed = 9.17 km/h
Velocity = 9.17 km/h, west
Speed = 550 km/h
Velocity = 550 km/h, west
Speed = 550 km/h, west
Velocity = 550 km/h, west
Speed = 9.17 km/h, west
Velocity = 9.17 km/h

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

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
