1. A particle is moving with the given data. Find the position of the particle.

a(t)=2t+7, s(0)=8, v(0)=-3

2.Find f

f'(x)=1 sqrt(1-x^{2) , f(1/2)=8}

(28) A 10-Micro Farat capacitor has been charged to a potential of 150 V. A resistor of 25 Ohms is then connected across the capacitor through a switch. When the switch is closed for ten time constants, the total energy (joules) dissipated by the resistor is?

Estimate the ground state for an electron confined to a potential well of width 0.200 nm and height 100 eV. What is the effective well width of the (infinite) well? (Hint: Consider an iterative approach to approximate the penetration depth ? by initially assuming E?V).

Pick five main reasons that caused the financial collapse of 2008 supporting it with the evidence described in the documentary and outside sources. Please ensure to provide the analysis using both domestic and international examples, as described in the documentary.

If a cylindrical steel pressure vessel has a 400-mm inner radius and 8-mm-thick walls. Find the change (mm) in the inner radius when the vessel is pressurized to 1.2 MPa. Use E = 200 GPa and v = 0.3 for steel.

A system contains H2O at P=150 kPa, v= 1.5 m^3 and a specific volume of 0.5 m^3/kg (state 1). It is heated at constant volume until the temperature reacues 160 celcius

What is the temperature at state 1 ?

A parallel plate capacitor is attached to 12 V battery. When an insulator of dielectric constant 6 is used to fill the air space between the capacitor plates, what happens to the energy stored and to the surface charge density on the plates if the battery is still attached?
