a rectangular container of base 50cm by 30cm is filled with water to a depth of 5cm. how much is the pressure exerted at the base?(take PW=1000 kg/meter cube and g=10 meter/second square)​

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.

What is a subatomic particle with a negative charge and very little mass?
