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=?

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply. the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
