Answer:
v = 8[m/s]
Explanation:
In this case, the work that is exerted on the cart is the kinetic energy that allows the movement, so we can use the following equation of kinetic energy.

Now replacing:
![128=0.5*4*v^{2} \\v=\sqrt{64} \\v=8[m/s]](https://tex.z-dn.net/?f=128%3D0.5%2A4%2Av%5E%7B2%7D%20%5C%5Cv%3D%5Csqrt%7B64%7D%20%5C%5Cv%3D8%5Bm%2Fs%5D)
Answer:
0.000025s
Explanation:
Period it’s. : T(s)= 1/f(Hz)=1/40000Hz=0.000025s
Jasmine need to correct the error by switching the headings on the columns adding the title parallel circuits.
<h3>What is a parallel circuit?</h3>
A parallel circuit is a circuit in which the components are connected to a common junction. This implies that if one bulb goes out in a parallel connection, all the bulbs will go out.
As such, Jasmine need to correct the error by switching the headings on the columns adding the title parallel circuits.
