A velocity selector consists of a uniform electric field of 3.4*10^6 V/m and a uniform magnetic field of 42.0 mT, perpendicular

to each other, through which a beam of muons is fired (muons are a particle with 207 times the mass and the same charge as an electron). If the muons travel in a straight line, then what must be their velocity

Answer:

The velocity of muons is 8.1\times 10^{7}m/s.

Explanation:

Electric field, E = 3.4\times 10^{6} V/m

Magnetic field, B = 42 mT = 0.042 T

mass, m =207 x mass of electron

charge, q = 1.6\times 10^{-19}C

Let the velocity is v.

The magnetic force on the charge is balanced by the electric force.

q v B sin 90 = q E

v x B = E

v x 0.042 = 3.4\times 10^6

v = 8.1\times 10^{7}m/s

Fofino [41]
When you add more water to the balloon, it makes it heavier. Therefore it would weigh the balloon down ( increasing mass) and increasing the energy to plummet down. So the answer is B.

Water is boiled at 1 atm pressure in a 25-cm-internal- diameter stainless steel pan on an electric range. if it is observed that
patriot [66]
<span>3933 watts At 100 C (boiling point of water), it's density is 0.9584 g/cm^3. The volume of water lost is pi * 12.5^2 * 10 = 4908.738521 cm^3 The mass of water boiled off is 4908.738521 * 0.9584 = 4704.534999 grams. Rounding to 4 significant figures gives me 4705 grams of water. The heat of vaporization for water is 2257 J/g. So the total energy applied is 2257 J/g * 4705 g = 10619185 J Now we need to divide that by how many seconds we've spent boiling water. That would be 45 * 60 = 2700 seconds. Finally, the rate of heat transfer in Joules per second will be the total number of joules divided by the total number of seconds. So 10619185 J / 2700 s = 3933 J/s = 3933 (kg m^2/s^2)/s = 3933 (kg m^2/s^3) = 3933 watts</span>
