Help please The “Brownie" camera was a popular camera not just because of a great advertising campaign by Eastman but because the average person could use it. Write a brief essay describing at least three ways the “Brownie" was made easier to use for the average citizen. (you dont have to write an essay but I need atleast three ways please!)​

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Which type of energy would have nothing to do with ironing clothes? a. heat b. chemical c. electrical d. mechanical

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
