<span>The equation for momentum is p = mv, where m is the mass of the object and v is its velocity. Through conservation of momentum, we know that the momentum of the rifle must be of the same magnitude and opposite direction to that of the bullet. Thus we can form two expressions for the respective momenta, set them equal, and solve for the recoil speed of the rifle.
718*0.0159 = vr*5.05 where vr is the rifle recoil speed.
Solving for vr = 718*0.0159/5.05 = 2.26 meters/second.</span>
Answer:
<em>Venus will need to use more voltage to have the same current</em>
Explanation:
<u>Ohm's Law</u>
It states that the current through a conductor is directly proportional to the voltage applied to it and inversely proportional to the resistance of the conductor. This relationship can be written as
Solving for V
Venus originally connected a resistance to a voltage to get some current I
The voltage needed to get that current is
If Venus changes the light bulb to another with higher resistance, say, , then the current would change, unless she uses another voltage
Venus will need to use more voltage to have the same current
