A 50-kg ice skater spins about a vertical axis through her body with outstretched arms. She makes 2 turns each second. The distance from one hand to the other is 1.60 m. Each hand makes up approximately...
force acting on a body of mass 1kg is related to its position x as F=(x^3-3x)N.it is at rest at x=1 . its velocity at x=3can be
the velocity of a particle moving on a x axis is given by v=x^2+x where v is in m/s and x is in m.find its acceleration in m/s^2when passing through point x=2m
Please show this using an x-axis that is parallel to the incline, and please show again using an x-axis that is horizontal. Thank you.
What is the normal force on a 1.10 kg lizard is sitting on a rock which is inclined 15 degrees from horizontal?
1.) A state trooper, observing car A traveling at an excessive speed, starts from rest and, with an initial, constant acceleration of 2.0 m s–2, chases the car. Car A, initially...
Hi there and welcome to my blog! This is my first post, with hopefully many to follow. In my undergraduate years, I learned about a very curious summation discovered by the great Ramanujan. Since then, whenever a student tells me that they hate mathematics and that it is stupid, I show this to them and they almost always see math in a new and enthusiastic light. Here, I will... read more
How do I determine an expression for the uncertainty of the equivalent capacitance of this circuit? I know that circuits in series are 1/Ceq = 1/C1 + 1/C2 ect. I know that circuits in...
I was hoping for an example with diagram for interference and diffraction problem with it focusing on physical locations. An example that includes 2 slits or more and then possibly...
I was hoping someone could give me an example with answer and reasoning using the Thin Lens Equation. The one we used in our lab was 1/f = 1/s + 1/s'. I was hoping...
I'm looking for an example with answer and reasoning dealing with Faraday's Law for a Physics 2 lab. The best example would be dealing with a magnet facing north and south. The equation...
I was wondering if anyone could give me an example with answer and reasoning. How would you draw a sine wave from a given circuit (could be rectification) and how would you draw a circuit...
There is a specific case where for a single converging lens the object distance equals the image distance. Find the relation between the focal length and the obect distance in this case. ...
Using the thin lens equation, prove that the focal length of a lens is equal to the image distance when there is parallel incident light.
I know I use 1/Ceq = 1/C1 + 1/C2 + 1/C3 ΔCeq = ?
