Explanation:
this is bcz they have higher kinetic energy compared to liquids and gases
Answer:
P.E = 0.068 J = 68 mJ
Explanation:
First we need to find the height attained by the ball toy. For this purpose, we will be using 3rd equation of motion:
2gh = Vf² - Vi²
where,
g = -9.8 m/s² (negative sign due to upward motion)
h = height attained by the ball toy = ?
Vf = Final Velocity = 0 m/s (since it momentarily stops at the highest point)
Vi = Initial Velocity = 3 m/s
Therefore,
2(-9.8 m/s²)h = (0 m/s)² - (3 m/s)²
h = (9 m²/s²)/(19.6 m/s²)
h = 0.46 m
Now, the gravitational potential energy of ball at its peak is given by the following formula:
P.E = mgh
P.E = (0.015 kg)(9.8 m/s²)(0.46 m)
<u>P.E = 0.068 J = 68 mJ</u>

Answer:
The electric field due to the right ring at a location midway between the two rings is ![2.41\times10^{3}\ V/m](https://tex.z-dn.net/?f=2.41%5Ctimes10%5E%7B3%7D%5C%20V%2Fm)
Explanation:
Given that,
Radius of first ring = 5 cm
Radius of second ring = 20 cm
Charge on the left of the ring = +30 nC
Charge on the right of the ring = -30 nC
We need to calculate the electric field due to the right ring at a location midway between the two rings
Using formula of electric field
Put the value into the formula
![E=\dfrac{9\times10^{9}\times30\times10^{-9}\times0.1}{((0.1)^2+(0.2)^2)^{\frac{3}{2}}}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B9%5Ctimes10%5E%7B9%7D%5Ctimes30%5Ctimes10%5E%7B-9%7D%5Ctimes0.1%7D%7B%28%280.1%29%5E2%2B%280.2%29%5E2%29%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%7D)
![E=2.41\times10^{3}\ V/m](https://tex.z-dn.net/?f=E%3D2.41%5Ctimes10%5E%7B3%7D%5C%20V%2Fm)
Hence, The electric field due to the right ring at a location midway between the two rings is ![2.41\times10^{3}\ V/m](https://tex.z-dn.net/?f=2.41%5Ctimes10%5E%7B3%7D%5C%20V%2Fm)
