A 1000 MW fission reactor consume half of its fuel in 5 years. How much did it contain initially? Assume that the reactor operates 80% of the time, that all the energy generates arises from the fissio
Biologists think that some spiders "tune" strands of their web to give enhanced response at frequencies corresponding to those at which desirable prey might struggle. Orb spider web silk has a typical
When mass M is tied to the bottom of a long, thin wire suspended from the ceiling, the wire's second-harmonic frequency is 150Hz . Adding an additional 1.5kg to the hanging mass increases the second-h
The potential energy of two atoms in a molecule can be approximated by the Morse function:U(r)=A[((e^((R-r)/s)-1)^2 )-1)] where r is the distance between the two atoms and A, R and S are positive

The image of a tree just covers the length of a plane mirror 3.60cm tall when the mirror is held 38.0cm from the eye. The tree is 24.0m from the mirror.What is the tree's height?
What is the saturation activity of 24Na that can be induced in a 400 g sample of NaCl with a constant thermal-neutron fluence rate of 5 x 1010 cm-2 sec-1?The isotope 23Na is 100% abundant and has a th
Consider a mass connected to 4 identical springs as shown. Each spring has spring constant k and unstretched length L0 and the length of each spring in this configuration is a (not necessarily L0).1.
A capacitor consists of three concentric spherical shells with radii R,2R and 3R. The inner and outer shells are connected by a wire (passing through a hole in the middle shell, without touching it),
Draw the cycloid curves for two turns with the following data.i. Cycloid with rolling circle radius 20 mm. ii.Superior/inferior trochoid with rolling circle radius 20 mm and generating circle rad
A wire is formed into a circle having a diameter of 10.3 cm and is placed in a uniform magnetic field of 3.25 mT. The wire carries a current of 5.00 A.Find the maximum torque on the wire. µ
Cirrus SR20 cruises at 155 kts at 8000 ft geometric altitude. Its wing has span, b = 38.333 ft, Sref = 144.9 ft2 & has a mean aerodynamic chord (MAC) = 4.04 ft.You will test a 1/4 scale
A count rate meter is used to measure the activity of a given sample. At one instant, the meter shows 4.750 counts/min. Five minutes later, it shows 2700 counts/min. Find a) the decay constant&nb
