Answer:
E=930.84 N/C
Explanation:
Given that
I = 1150 W/m²
μ = 4Π x 10⁻⁷
C = 2.999 x 10⁸ m/s
E= C B
C=speed of light
B=Magnetic filed ,E=Electric filed
Power P = I A
A=Area=4πr² ,I=Intensity
![I=\dfrac{CB^2}{2\mu_0}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7BCB%5E2%7D%7B2%5Cmu_0%7D)
![I=\dfrac{CE^2}{2\mu_0 C^2}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7BCE%5E2%7D%7B2%5Cmu_0%20C%5E2%7D)
![E=\sqrt{{2I\mu_0 C}}](https://tex.z-dn.net/?f=E%3D%5Csqrt%7B%7B2I%5Cmu_0%20C%7D%7D)
![E=\sqrt{{2\times 1150\times 4\pi \times 10^{-7}(2.99792\times 10^8)}}](https://tex.z-dn.net/?f=E%3D%5Csqrt%7B%7B2%5Ctimes%201150%5Ctimes%204%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%282.99792%5Ctimes%2010%5E8%29%7D%7D)
E=930.84 N/C
Therefore answer is 930.84 N/C
Answer:
The height is the same
Explanation:
Because they were at the same height but they fell at different velocities
Given:
Water, 2 kilograms
T1 = 20 degrees Celsius, T2 = 100
degrees Celsius.
Required:
Heat produced
Solution:
Q (heat) = nRT = nR(T2 = T1)
Q (heat) = 2 kilograms (4.184 kiloJoules
per kilogram Celsius) (100 degrees Celsius – 20 degrees Celsius)
<u>Q (heat) = 669.42 Joules
</u>This is the amount of heat
produced in boiling 2 kg of water.
