We know, Impulse of a body is change in momentum.
Also, the final velocity of wood block is 0 m/s.
So, Impulse = Final Momentum - Initial Momentum
Impulse = 0 - ( 0.05 kg × 350 m/s )
Impulse = - 17.5 kg m/s
Therefore, the impulse exerted by the wood on the bullet is -17.5 kg m/s .
B is true, however that is not a way in which conserving and recycling paper helps manage energy sources...
Explanation:
... in every interaction, there is a pair of forces acting on the two interacting objects. The size of the force on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
Answer:
The capacitance of a capacitor depends on the charge and voltage of a system. It is also dependent, if present, on the dielectric as well.
General Formulas and Concepts:
<u>Gauss's Law</u>
Capacitance Formula: 
- <em>Q</em> denotes charge
- <em>V</em> denotes voltage
Dielectric Capacitance Formula: 
- <em>C₀</em> denotes original capacitance
- <em>κ</em> denotes the dialectic constant
Explanation:
A <u>capacitor</u> <em>stores</em> charge when run through an electrical current. The <u>capacitance</u> is <em>how much </em>charge a capacitor can hold.
We can define the relationship of capacitance by using the formula. Capacitance is <em>inversely proportional</em> to the potential energy, or <u>voltage</u>, of the system. Therefore, you will need to know what the <u>charge</u> Q of the system as well has voltage V in order to find the capacitance.
If there is a dielectric involved inside the capacitance, you also must incorporate the value of the <u>dielectric constant </u>into your capacitance. A dielectric is <em>directly proportional </em>to the capacitance; the bigger the dielectric constant, the bigger capacitance, as denoted in our equation.
