Using Biot-Savart law to find the magnitude of the magnetic field at the centre of a current carrying circular loop. 

 (ans in pdf please)

60 A current is supplied in a long and straight wire P is a point at a distance of 40 cm from the wire. Then the wire is bended to a circular coil of radius of 40 cm the center of which is Q.

Calculate the magnitude of the magnetic field at point p

I need a burning question about some aspect of nanomedicine ?

MM398 is a liposome based cancer nanomedicine designed to minimize toxicity of the therapeutic Agent irinotecan.

How does this nanomedicine achieve this? 

How do you determine whether a molecule is polar?

Question 7 Suppose that 5 independent trials, each of which results in any of the outcomes 0, 1, or 2, with respective probabilities 0.3, 0.5, and 0.2, are performed. Find the probability that both outcome 1 and outcome 2 occur at least once. (Hint: Consider the complementary probability.)

Show the bond polarities of trichloromethane and state whether the molecule is a polar molecule along with the lewis structure.
