Gravity Gravitational Force of Gravity
Answer:
<u>ω = 1.7 rad/s</u>
Explanation:
Conservation of angular momentum
Assuming the rod is initially hanging vertically at rest.
Initial angular momentum is carried by the bullet only
L = Iω = (mR²)(v/R) = mvR = 0.020(200)(0.7) = 2.8 kg•m²/s
the same angular momentum exists after impact, only the moment of inertia has increased by that of the rod. I = ⅓mR²
2.8 = (⅓(10)(0.7²) + 0.020(0.7²))ω
2.8 = (1.64313333...)ω
ω = 1.70406134...
Answer:
You put the add sign, so it would be 49. I don't believe that is what you meant to put though.
Explanation:
A mix
Explanation:
A battery is an electrochemical cell that converts chemical energy into electrical energy. The chemical reactions in a battery ensures that current is produced.
- A battery is made up of two electrodes which are the cathode and anode.
- The cathode is the positive electrode and the anode is the negative one.
- These electrodes are made up of metals.
- Electrons moves from the anode to the cathode and current flows from cathode to anode.
- At the anode oxidation occurs because electrons are produced here.
- It needs to have low electron affinity.
- At the cathode where reduction occurs, the electron affinity must be high.
- This is the driving force for the production of electricity in electrochemical cells.
