A)Find the velocity of a wheel that has a diameter of 2m and angular velocity of 5 rad/s. b) If the wheel has an angular acceleration of 3.0rad/s/s for 4 seconds then what is its final angular velocity and angular displacement?
Given: d=2m, ⍵o=5rad/s,=3.0rad/s2 ,Δt=4s

Unknown:v=?, b) ⍵f =? and Δϴ=?

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
