Answer:
the velocity is 10 m/s
Explanation:
Using the expression for kinetic energy we have:
![Ek=\frac{1}{2} *m*v^{2} \\\\Ek=100J\\m=2kg\\v=\sqrt{(2*100/2)}\\ v=10[m/s]](https://tex.z-dn.net/?f=Ek%3D%5Cfrac%7B1%7D%7B2%7D%20%2Am%2Av%5E%7B2%7D%20%5C%5C%5C%5CEk%3D100J%5C%5Cm%3D2kg%5C%5Cv%3D%5Csqrt%7B%282%2A100%2F2%29%7D%5C%5C%20v%3D10%5Bm%2Fs%5D)
Evaporation (or another word to use is water vapor.)
Tidal waves are caused by winds and high tides, and a tidal range changes. there you go
Answer:
Part a)

Part b)

Explanation:
Part a)
For force conditions of two blocks we will have


now from above equations we have


now we know that


now from above equation we have


Part b)
When heavier block is removed and F = 908 N is applied at the end of the string then we have



Answer:
<h2>
0.147136N/m²</h2>
Explanation:
Pressure is defines as force exerts by a body per its unit area.
Pressure = Force/Area
Given the total force exerted by the gas = 6.05N
Area of the rectangular container = 0.121 m * 0.201 m = 0.024321m²
Pressure of the sample = 6.05/0.02432
Pressure of the sample = 0.147136N/m²
