Two flat surfaces are exposed to a uniform, horizontalmagnetic field of magnitude 0.49 T. When viewed edge-on, the firstsurface is tilted at an angle of 11° from the horizontal, and anet magnetic flux of 8.00 10-3 Wb passes through it. The same netmagnetic flux passes through the second surface.
a. Determine the area of the first surface.b. Find the smallest possible value for the area of the second surface.
If alpha particles are caused to fall through a potential difference of 1500 volts, determine their final speed if they were initially at rest. An alpha particle has mass 6.68*10^-27kg and charge of +2e. Alpha particles are Helium nuclei.
What is the wavelength of the spectral line? B) Assuming this line is from a transition from level n1 = 3 to level n2 = 2 (i.e. the longest wavelength Balmer series transition), what do you calculate for the value of Rydberg constant.
A sphere completely submerged in water is tethered to the bottom by a string. The tension in the string is 1/5 (aka one-fith) the weight of the sphere. What is the density of the sphere
The bones of a saber-toothed tiger are found to have an activity per gram of carbon that is 14.70 of what would be found in a similar live animal. How old are these bones.
A series ac circuit consists of a voltage source of frequency f=60 Hz and source voltage amplitude 345 volts, a resistor of resistance R=335 ohms, what is the current amplitude in the circuit
A 2kg ball moving east with a speed of 3m/s collides with another 3kg ball moving west with a speed of 4m/s . After the collision the two balls stick together

A generator uses a coil that has 140 turns and a 0.50-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. assume that each turn of the coil is a square (an approximation), find out the length of the..
An initially motionless test car is accelerated uniformly to 145 km/h in 8.28 seconds before striking a simulated deer. The car is in contact with the faux fawn for 0.455 seconds, after which the car is measured to be traveling at 60.0 km/h.
