Answer:
Equal
Explanation:
The impulse theorem states that the impulse exerted on each cart is equal to the change in momentum of the cart:
where
I is the impulse
pf is the final momentum
pi is the initial momentum
The impulse is equal to the product between the force applied and the contact time:
In this case, the force applied to the two carts (F) is the same, and the contact time (
) is the same as well. Therefore, the impulse exerted on the two carts is the same.
Moreover, the initial momentum of the two carts is also the same (zero, because they start from rest: 
). So the formula becomes
And since I is the same for the two carts, the final momentum (
) will also be equal.
just analyze it in this way:
20cos30*=10( radical 3 )
20sin30*=10
If two sources emit waves with the same wavelength and a constant phase difference ϕ, they are said to be coherent.
<h3>What is coherent source ?</h3>
- If the frequency and waveform of two wave sources are the same, they are coherent. Waves' optimal quality of coherence makes stationary interference possible.
- When the phase difference between two beams of light is constant, they are coherent; if the phase difference is random or changes, they are noncoherent.
- The concept of a superpositioning at the core of quantum physics and quantum computing is referred to as "quantum coherence." Quantum coherence specifically considers a scenario in which a wave property of an item is split in two and the two waves coherently interfere with one another.
- The interference visibility, which examines the size of the interference fringes in relation to the input waves, is an easy way to measure the degree of coherence; correlation functions provide a precise mathematical definition of the degree of coherence.
