The correct option is: (C) <span>when one does not have enough resources to satisfy all of one’s wants
Explanation:
Scarcity in Economics is defined as the "unlimited wants and limited resources." If a someone's wants cannot be satisfied because of the limited resources, then it signifies the condition of scarcity. Hence in the options given the only option that satisfies this definition is option C. </span>
I'd Say B :) Your Welcome LOL!!!!!
Answer:
Explanation:
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Other sources include X-rays from medical radiography examinations and muons, mesons, positrons, neutrons and other particles that constitute the secondary cosmic rays that are produced after primary cosmic rays interact with Earth's atmosphere.
Answer:
I = (5.71 i ^ + 6.99j ^) N s
Explanation:
The concept of impulse is very useful for problems where shocks occur, the impulse is equal to the change of moment of the system
I = Δp = m -m v₀
Let's fix an xy coordinate system, where y is vertical and we decompose the velocities
Initial
sin (-40) = / vo
cos (-40) = v₀ₓ / Vo
= 17.0 sin (-40)
= -10.93 m / s
Vox = 17 cos (-40)
Vox = 13.02 m / s
Final
sin 30 = / vf
cos 30 = / Vf
= 48.0 sin30
= 24.0 m / s
= 48 cos 30
= 41.57 m / s
Let's calculate the momentum on each axis
X axis
Iₓ = m -m
Iₓ = 0.200 (41.57 - 13.02)
Iₓ = 5.71 N s
Axis y
= m - m
= 0.2000 (24 - (-10.93))
= 6.99 N s
I = (5.71 i ^ + 6.99j ^) n s
