An undersea explosion occurs. If the sea water has density 1.03 x 10 3 kg/m3 and Bulk Modulus of 2.41x10 9 Nm -2 ; a) Determine the velocity of sound in sea water b) If
What are Newton s laws of motion? 1. A body at rest will stay at rest and one in motion will stay in motion, unless and unless acted upon by an external force. (Law of inertia)
According to their frequencies, waves are separated into three categories: (1) Audible or sound waves : Range 20 Hz to 20 KHz. These are formed by vibrating bodies like as voc
A charge of 111 pC is uniformly distributed throughout the volume of an isolated sphere of diameter 40 cm. Calculate the electric field at the following distances from the centre o
When you are talking about relative velocity of A with respect B then it''s like you are observing the motion of A while standing on B. That is, with respect to you, B is at rest.
