The velocity of a particle which moves along
the s-axis is given by
V=2 - 4t + 58312
, Where t is in seconds and v is
in meters per second. Evaluate the position s,
velocity v, and acceleration a when t = 3 s. The
particle is at the position S, = 3 m when t=0.
At the center of a cube of edge 80.0cm, a charge of 170 µC is found. (1 µC = 10-6 Coulombs) (Permittivity
of free space (ϵ0) 8.85x10-12 C2 / N.m2)
The angular acceleration of a wheel is α = 9.0t4 – 5.0t2, with α
in radians per second-squared and t in seconds. At time t = 0, the wheel has an angular velocity of +7 rad/s and an angular position of +5 rad. Write expressions for (a) the angular velocity (rad/s) and (b) the angular position (rad) as functions of time (s).
The angular position of a point on a rotating wheel is given by θ = 3.04 + 4.83t2 + 2.99t3, where θ is in radians and t is in seconds. At t = 0, what are (a) the point's angular position and (b) its angular velocity? (c) What is its angular velocity at t = 7.43 s? (d) Calculate its angular acceleration at t = 1.12 s. (e) Is its angular acceleration constant?
You are to construct a parallel plate capacitor out of two flat plate of area 25 cm^2. You
have three dielectrics to choose from: 1 cm thick paraffin, 2 cm thick Pyrex glass, and 3 cm thick Porcelain which of the dielectric will you used to get the maximum capacitance?
A stone is thrown straight upward with a velocity of 30 m/s. What was its maximum height?, b) What is the time taken to reach the maximum height?, c) What is the velocity of the stone when it is 60 m from the ground? (Assume the ground as the initial frame of reference)
Two conducting plates with a length of 1 m and a width of 0.5 m has polyethylene between them. What is the capacitance if the capacitor is 1 m high?
. Dry air will support a maximum electric field strength of about 2.0 x 108 V/m. Above that value, the field creates enough ionization in the air to make the air a conductor. This allows a discharge or spark that reduces the field. What, then, is the maximum voltage between two parallel conducting plates separated by 3.5 cm of dry air?
What are Newtonian and non-Newtonian fluids?
