What is the: A) angular speed B) linear speed C) centripetal force 2. A bicycle wheel turns at a constant angular velocity of 10 rad/sec. What is the distance travelled by the bicycle in 30 minutes if the radius of the wheel is 20cm? 3. A bicycle wheel has a radius of 0.4m and a point on its rim moves with a speed of 6m/s. What is its angular velocity? 4. The angular velocity of a body increases from 4rad/sec to 16rad/sec If the angular acceleration ofthe body is 4 rad /s2, calculate: A) the angular distance. B) the angular speed at t=2s. 5. Convert one unit of angular displacement to another. A) 42 rev to radian B) 60 to rad ) 4 radian to rev 6. A trolley moves round a circular track of radius 0.3m at 2rev/s. What is the value of: A) angular speed B) period? C) linear speed

m × a just put them in and solve

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
