Explanation:
It is given that,
Electric field experienced by an electron,
Charge on electron,
Mass of electron,
The electric force is balanced by the force acting on electron as,
ma = qE
So, the acceleration of the electron is . As the electron is a negatively charged particle, the field lines is from negative to positive charge.
Answer:
Blue
Explanation
The Sunlight that enters the atomosphere is blue.
"Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. ... More of the sunlight entering the atmosphere is blue than violet, however, and our eyes are somewhat more sensitive to blue light than to violet light, so the sky appears blue".
You can increase the moment of inertia of a beam without increasing its cross sectional area by <span>making the beam more solid by using more material or material with a higher density. Also, you could deflate the air out of it so it has less tendency to rise with hot air currents.</span>
mass = 177 x 1.0 g/mL= 177 g mass ethanol = 177 x 10.6/100 = 18.8 g moles = 18.8 g/46.069 g/mol = 0.408 1367 kJ/mol x 0.408 mol= 557.9 kJ
