What is the average speed in 4 seconds going 8 meters

Aparticle with mass 1.81×10−3 kg and a charge of 1.22×10−8 c has, at a given instant, a velocity v⃗ =(3.00×104m/s)j^. what are the magnitude and direction of the particle’s acceleration produced by a uniform magnetic field b⃗ =(1.63t)i^+(0.980t)j^?

Avalue that describes how heavy an object is and is related to the force of gravity is

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
