in some facilities, real-time MRI is used to monitor a treatment. This imaging allows the treatment to be adjusted to achieve optimum results. However, the devices that deliver the treatment can themselves produce magnetic fields that interfere with the imaging in one case, a device produces a 65 CT static feld parallel to the 1.5 Tr the MRI machine By how much does this additional field change the proton's precession frequency?

The diagram shows a mass spectrometer used for measuring the masses of isotopes. It consists of an ion generator and accelerator, a velocity selector, and an ion separator, all in a vacuum. In one experiment, tin ions, each of which carries a charge +1.6 × 10-19C, are produced in the ion generator and are then accelerated by a p.d. of 20kV. Tin has a number of isotopes, two of which are tin-118 (118Sn) and tin-120 (120Sn). What will be the final speed of an ion of tin-118?

A radio transceiver sends out 4.3 mW at 5.8 GHz. The specifications clarify that the radio transceiver has a range of 100 feet.

The diagram shows a mass spectrometer used for measuring the masses of isotopes. It consists of an ion generator and accelerator, a velocity selector and an ion separator, all in a vacuum. In one experiment, tin ions, each of which carries a charge +1.6 × 10-19C, are produced in the ion generator and are then accelerated by a p.d. of 20kV. Tin has a number of isotopes, two of which are tin-118 (118Sn) and tin-120 (120Sn). (a.) In practice, all ions produced by the ion generator have a range of speeds. A velocity selector is used to isolate ions with a single speed. In the velocity selector, the isolated ions go through undeviated, though being acted upon by forces from both the electric and magnetic fields. (i.) Write down the condition and equation which must be satisfied if the ions are to emerge from the exit hole of the velocity selector. Define the terms in the equation. Redraw the section of thevelocity selector and indicate the different forces acting on the ions there and use…

Solve the following: A proton (of mass, m-1.67 x 1027kg) starts moving in a circular path of radius 5 cm when it enters perpendicular to the Earth's magnetic field of 1.75 x 10-5 T. Calculate Bin the speed X. of the cosmic ray proton in (m/s) ? X +q tu

A 4.3-MeV (kinetic energy) proton enters a 0.21-T field, in a plane perpendicular to the field.  What is the radius of its path?

Two blocks, M=B.00 kg and m=2.00 kg are being pulled across a rough floor(u k=0.14) by a force of FO= 68N directed 52 degrees above the horizontal, as shown. The top block m cannot slide on the bottom block so the system can be treated as a single 10.0 kg block which we will call MT Fo, M-2.0 ks 520 M-8.0kg
