Answer:
C
Explanation:
Environmental factors provides ambiguity a particular one could be studied to see how it affects recyclable plastics.
Answer:
density ρ = mass / volume
ρ = 100 g / 11.2 cm^3 = 8.93 g/cm^3
Probably copper because a value given for Cu is 8.89 g/cm^3
Answer:
Acceleration (a) is defined as the rate of change of velocity. Velocity is a vector quantity, and therefore acceleration is also a vector quantity. The SI unit of acceleration is metres/second2 (m/s2).
Answer: waves
Explanation:
Rhythmic disturbances that carry energy without carrying matter are called waves
Work is measured in joules, so you're question was already answered! 75 joules of work was required.
However, if you're asking about the force that was required, you're answer would be 25 N of force.
work= force x distance
75= f x 3
75= 25 x 3
