An alpha particle (a he nucleus, containing two protons and two neutrons and having a mass of 6.6. an alpha particle (a he nucleus, containing two protons and two neutrons and having a mass of 6.64×10−27 kg ) traveling horizontally at 36.6 km/s enters a uniform, vertical, 1.10 t magnetic field.
(a)- what is the diameter of the path followed by this alpha particle? express your answer in millimeters to three significant figures.
(b)- what effect does the magnetic field have on the speed of the particle?
(c)- what is the magnitude of the acceleration of the alpha particle while it is in the magnetic field? express your answer in meters per second to three significant figures.
(d)- what is the direction of the acceleration of the alpha particle while it is in the magnetic field?
(e)- explain why the speed of the particle does not change even though an unbalanced external force acts on it.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
