A projectile is launched horizontally 1m above the ground. If it lands 300m away from the initial launch position, find: a) - the initial launch velocity, u, and b) - the angle 0, at which the projectile contacts the ground.

A budding electronics hobbyist wants to make a simple 1.0-nF capacitor for tuning her crystal radio, using two sheets of aluminum foil as plates, with a few sheets of paper between them as a dielectric. The paper has a dielectric constant of 3.

What is the governing ratio for thin walled cylinders?

What is the net force acting on a car cruising at a constant velocity of 70 km/h (a) on a level road and (b) on an uphill road?

Consider the flow past a 30-degree expansion corner. The upstream conditions are M1 = 2, P1 = 3 atm, and T1 = 400 K. Calculate the following downstream conditions: M2, P2, T2, T02, and P02.

Just upstream of a shock wave, the air temperature and pressure are 288 K and 1 atm, respectively; just downstream of the wave, the air temperature and pressure are 690 K and 8.656 atm, respectively.
