By definition,
Momentum = Mass * Velocity.
Therefore the velocity, v, is determined by
(30000 kg-m/s) = 400 kg)(v m/s)
30000 = 400v
v = 30000/400 = 75 m/s
Answer: 75 m/s
Answer:
Yes
Explanation:
The core of an electromagnet serves to stabilize the magnetic field created by the wire. The thicker the core, the more metal there is to amplify the current. Therefore, a thicker core does make an electromagnet stronger. Hope this helps!
The efficiency of the light bulb is 8.9%. This means that only 8.9% of the power of the lightbulb becomes useful power, and it corresponds to:
The rest of the power instead is wasted as heat, and this amount of power wasted is given by the difference between the total power and the useful power:
So, the power wasted as heat is 13.66 W.
