Answer:
![523269.9\ \text{N/m}](https://tex.z-dn.net/?f=523269.9%5C%20%5Ctext%7BN%2Fm%7D)
Explanation:
q = Charge
r = Distance
![q_1=25\ \text{C}](https://tex.z-dn.net/?f=q_1%3D25%5C%20%5Ctext%7BC%7D)
![r_1=3000\ \text{m}](https://tex.z-dn.net/?f=r_1%3D3000%5C%20%5Ctext%7Bm%7D)
![q_2=40\ \text{C}](https://tex.z-dn.net/?f=q_2%3D40%5C%20%5Ctext%7BC%7D)
![r_2=850\ \text{m}](https://tex.z-dn.net/?f=r_2%3D850%5C%20%5Ctext%7Bm%7D)
The electric field is given by
![E=E_1+E_1\\\Rightarrow E=k(\dfrac{q_1}{r_1^2}+\dfrac{q_2}{r_2^2})\\\Rightarrow E=9\times 10^9\times (\dfrac{25}{3000^2}+\dfrac{40}{850^2})\\\Rightarrow E=523269.9\ \text{N/m}](https://tex.z-dn.net/?f=E%3DE_1%2BE_1%5C%5C%5CRightarrow%20E%3Dk%28%5Cdfrac%7Bq_1%7D%7Br_1%5E2%7D%2B%5Cdfrac%7Bq_2%7D%7Br_2%5E2%7D%29%5C%5C%5CRightarrow%20E%3D9%5Ctimes%2010%5E9%5Ctimes%20%28%5Cdfrac%7B25%7D%7B3000%5E2%7D%2B%5Cdfrac%7B40%7D%7B850%5E2%7D%29%5C%5C%5CRightarrow%20E%3D523269.9%5C%20%5Ctext%7BN%2Fm%7D)
The electric field at the aircraft is ![523269.9\ \text{N/m}](https://tex.z-dn.net/?f=523269.9%5C%20%5Ctext%7BN%2Fm%7D)
Answer:
w= p∆v 50000 ( 0.55-0.40) and calculate and you get it
A prism will separate white light into a rainbow of light
The coin would probably slowly slide down whichever end it is closer to, weigh down the end of the paper, and fall off. It kinda depends on how you hold the paper though, because if it is directly in middle, and you hold it on both ends, it will stay on the paper.
The initial speed of the vehicle before the collision is 8 m/s.
- Let the mass of the vehicle = m
- Let the initial speed of the vehicle stopped = u
- The initial speed of the vehicle parked at the red light = 0
<h3>Principle of conservation of linear momentum</h3>
- The initial speed of the vehicle before the collision is calculated by applying principle of conservation of linear momentum as follows;
![m_1 u_1 + m_2 u_2 = v(m_1 + m_2)\\\\mu + m(0) = 4(m+ m)\\\\mu = 4(2m)\\\\mu = 8m\\\\u = 8 \ m/s](https://tex.z-dn.net/?f=m_1%20u_1%20%2B%20m_2%20u_2%20%3D%20v%28m_1%20%2B%20m_2%29%5C%5C%5C%5Cmu%20%2B%20m%280%29%20%3D%204%28m%2B%20m%29%5C%5C%5C%5Cmu%20%3D%204%282m%29%5C%5C%5C%5Cmu%20%3D%208m%5C%5C%5C%5Cu%20%3D%208%20%5C%20m%2Fs)
Thus, the initial speed of the vehicle before the collision is 8 m/s.
