Solve the following:
d/dt cos(theta)
d/dt t sin(theta)
d/dt r cos (theta)
d/dt r^2 (theta)
d/dt e^ (-3x)
d/dt (x^2 + y^2)
I would assume all by the second one are 0 since your solving for terms dt and not theta, x, y, or r... I don't think its right at all. I know it goes something...
So there is a ladder leaning against the wall. its a 2.5 (base), 6 (height), 6.5 (hyp) triangle. the coefficient of static friction is zero at B (corner of 6 & 6.5). we need to determine the smallest value of Ms at A (corner of 2.5 & 6.5) for which equilibrium will be maintained.
They do not...
So the problem states that I have a crate that is 24 inch wide. it weighs a 120 ib (roughly 2590N) and I have to determine a) the force required to move the cabinet to the right &
b) min height so the crate doesn't tip
part a was easy, it came out to be 777N. I am just stuck on the min...
let x(t)= 1+t and y(t)= t/2
trace (x(t),y(t)) as t advances from 0 to 2.
Im just unsure of how to trace it. Is it pretty much the same thing as tracing it from 0 to 2pi except I am leaving out the pi?
So axis in term of t:
positive x= 0 or 2
positive y= 1/2
negative x= 1
negative...
An infinite line of charge with linear density λ = 7.6 μC/m is positioned along the axis of a thick insulating shell of inner radius a = 3 cm and outer radius b = 5 cm. The insulating shell is uniformly charged with a volume density of ρ = -611 μC/m3. (see attachment)
What is Ex(R), the value...
A point charge q1 = -7.5 μC is located at the center of a thick conducting shell of inner radius a = 2.9 cm and outer radius b = 4.9 cm, The conducting shell has a net charge of q2 = 2.3 μC. (see attachment)
1. What is Ex(P), the value of the x-component of the electric field at point P...
Using the root test find whether the series converges or diverges:
Lim Sin (4/(3n+3)) / Sin (4/(3n))
n-> inf.
I have no idea how to cancel out the sin terms
