$1.05\times 10^{-26}J$

Explanation:

The uncertainty in energy is given by $\Delta E=\frac{h}{2\pi \Delta t}$

here h is plank's constant which value is $6.67\times 10^{-34}$ and $\Delta t$ is the time interval which is given as $1.2\times 10^{-8}sec$

So using all the parameters the smallest possible uncertainty in electrons energy is $=\frac{6.67\times 10^{-34}}{2\times \pi \times 1.2\times 10^{-8}}=1.05\times 10^{-26}J$

y-intercept=15 b/c it is the b value in y=mx+b or you can plug in 0 for x, and get 15 also

x-intercept=3 b/c when y is 0, x is 3

slope= -5 b/c it is the value of m in y=mx+b
