[b]1. Given only one 30Ω and one 60Ω, calculate all possible values of resistance that can be obtained.
[b]2.I am not certain of which equation I should be using ... I never had other problems which gave only this information, usually the voltage is given or the current.
[b]3. Here...
Ok so ... let's say I have a 6kg object, I know the coefficient of static force is 0.42, and I want to know what force is required to move the object ...
so I start by finding the normal force of the object by multiplying the mass and force of gravity
which would be: Fn= 6kg X 9.81m/s2=...
How can we find the horizontal force required to move an object with the coefficient of static friction and the mass??
I just need a formula please, thankyou
