A Physics major with a minor in medical physics. Experience in both physics and biology during my undergraduate research. Looking forward to my PhD in radiation biology.
(I) What is the total energy of a proton whose kinetic energy is 4.65 GeV?
(I) If $\alpha$ particles are accelerated by the cyclotron of Example 32-2, what must be the frequency of the voltage applied to the dees?
(I) What is the time for one complete revolution for a very high-energy proton in the 1.0-km-radius Fermilab accelerator?
(II) What strength of magnetic field is used in a cyclotron in which protons make $3.1 \times 10^7$ revolutions per second?
(II) (a) If the cyclotron of Example 32-2 accelerated $\alpha$ particles, what maximum energy could they attain? What would their speed be? (b) Repeat for deuterons $(^{2}_{1}H)$. (c) In each case, what frequency of voltage is required?
(II) The 1.0-km radius Fermilab Tevatron took about 20 seconds to bring the energies of the stored protons from 150 GeV to 1.0 TeV. The acceleration was done once per turn. Estimate the energy given to the protons on each turn. (You can assume that the speed of the protons is essentially c the whole time.)
The force of gravitational attraction between two masses is 99 N. What will be the force if one mass is changed by a factor of 9, the other mass by a factor of 11 and the distance between them is decreased 7 times?
Record your answer to whole number.
If you were to place yourself with mass 67 kg between the moon and the Earth, how far away, in km, from the surface of Earth would you have to be in order that the net force on you is zero?
Consider the followings:
Mass of Earth: 5.97 × 1024 kg
Radius of Earth: 6,371 km
Mass of Moon: 7.35 x 1022 kg
Radius of Moon: 1,737.5 km
Distance from center of Earth to center of Moon: 385,000 km
Record your answer to two digits after the decimal point.
Two blocks are connected by massless string that is wrapped around a pulley. Block 1 has a mass m1=6.50 kg, block 2 has a mass m2=2.80 kg, while the pulley has a mass of 1.60 kg and a radius of 16.2 cm. When the pulley turns, there is friction in the axel that exerts a torque of magnitude 0.220 N m.
If block 1 is released from rest at a height h=1.00 m, how long does it take to drop to the floor?
QUESTION 1
A box of mass 12 - kg is accelerated from rest across a floor at a rate of 4.3 m/s2 for 10 s. Find the net work done on the box
A 1,457- kg roller coaster car moves from point 1 in figure to point 2 and then to point 3. What is the change in gravitational potential energy in going from point 2 to point 3, relative to point 1. (take y = 0 at point 1)
h1 = 9 m
h2 = 22 m
g = 9.8 m/s2
A block attached to a spring oscillates in simple harmonic motion along an x-axis. The block moves from x=29cm to x=75cm and it goes from one of these extremes to the other in 0.2 sec. The amplitude, in cm, is
