Abeam of electrons is accelerated from rest and then passes through a pair of identical thin slits that are 1.45 nm apart. you observe that the first double-slit interference dark fringe occurs at ±16.0 ∘ from the original direction of the beam when viewed on a distant screen.

hi!

the answer is 8 m/s^2

acceleration is defined as the rate of change of an object's velocity, per unit time. meaning, the rate at which an object is increasing/decreasing its velocity with the passage of time in a given period.

if an object is moving at constant velocity, its acceleration would be 0, because there is no change in velocity. in our case, the velocity is increasing, and to calculate this, we will use a simple formula,

acceleration = change in velocity / time

and change in velocity is calculated by subtracting the value of initial velocity (u) from final velocity (v).

u = 7m/s

v = 15m/s

t= 1s

a = ?

a = u - v / t

a = 15 - 7 / 1

a = 8 m/s^2

hope this !

answer: the new volume obtained is 45 ml.

explanation:

to obtain new volume, we use the equation given by charles' law. this law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

mathematically,

or,

we are given:

conversion factor:

putting vales in above equation, we get:

hence, the new volume obtained is 45 ml.
