<h3>IMPULSE AND MOMENTUM</h3>
==============================
- Why is impulse and momentum important in sports like cricket??
==============================
Impulse and momentum are important in sports like cricket because from the word "<em>momentum</em>" it describe itself like you're getting used of it or you know what to do like there's no stopping you.
==============================
<u>How </u><u>a</u><u>r</u><u>e</u><u> </u><u>impulse and momentum</u><u> </u><u>related?</u>
==============================
20 g = 20 / 1000 = 0.02 kg.
Magnitude of momentum of the sparrow = mass * velocity
= 0.02 * 8.1
= 0.162 kg-m/s. (answer)
Answer:
4 Ohms
Explanation:
The challenging part in this circuit is the bridged setup (diamond-shaped arrangement made of the 4 Ohm resistors). In general, this would first need to be transformed using the Wye-Delta transform to be solved, but in this case we can make a valid simplification: since the diamond arrangement is completely symmetrical, the voltage at the top and the bottom tip of the "diamond" will be identical and no current flows through the 4 Ohm bridge, hence, this resistor can be removed without changing the resulting resistance. After this, it is easy to see that the equivalent resistance of the modified "diamond" is just 4 Ohms.
The remaining top parallel branch of the circuit will be 8 Ohms, and the bottom parallel branch is nominally 8 Ohms. The resulting resistance therefore is 4 Ohms.
(The answer is not 2 Ohms!)
