A light bulb has an illuminance of 19.9 lx at a distance of 2 m . What is the luminous flux of the bulb? Note: E=P/4πr^2

Aparticle initially located at the origin has an acceleration of = 2.00ĵ m/s2 and an initial velocity of i = 8.00î m/s. find (a) the vector position of the particle at any time t (where t is measured in seconds), (b) the velocity of the particle at any time t, (c) the position of the particle at t = 7.00 s, and (d) the speed of the particle at t = 7.00

How can a cyclist's acceleration change even if its velocity remains constant?
