Answer: the force when the catapult swings has the same force as it does when coming down
Explanation:
for every reaction there is an equal opposite reaction
Answer:
b. The voltage across the resistor is equal to the terminal voltage of the battery, and the voltage across the capacitor is zero.
Explanation:
<em>When the system reaches its steady state the current tends to zero, then</em>
<em>in the resistor</em>
<em>V=IR</em>
<em>I=0, then </em><em>V=0</em>
<em>the capacitor charged is like an interruption in the circuit. </em><em>If we mesure voltage on both sides of the battery and if we mesure both sides of the capacitor, we will get the same value</em><em>, as its not any component between them in one side, and, in the other, the only component is the resistor that, without any courrent doesn't discipates any energy.</em>
22.5 J

Answer and Explanation:
In optics, a CoC(Circle of Confusion) is defined the minimum cross section of a paraxial bundle of rays made by a lens which is sphero-cylindrical type and can be viewed as an optical spot, which do not converge perfectly at the focus while a point source is being imaged due to spherical aberration.
The Circle of Confusion is also referred to as circle of indistinctness or a blur spot
