An electron emitted from a filament is travelling at 1.5 x 105 m/s when it enters an acceleration of an electron gun in a televi
Crank

Answer:

The acceleration of the electron is 1.457 x 10¹⁵ m/s².

Explanation:

Given;

initial velocity of the emitted electron, u = 1.5 x 10⁵ m/s

distance traveled by the electron, d = 0.01 m

final velocity of the electron, v = 5.4 x 10⁶ m/s

The acceleration of the electron is calculated as;

v² = u² + 2ad

(5.4 x 10⁶)² = (1.5 x 10⁵)² + (2 x 0.01)a

(2 x 0.01)a = (5.4 x 10⁶)² - (1.5 x 10⁵)²

(2 x 0.01)a = 2.91375 x 10¹³

a = \frac{2.91375 \ \times \ 10^{13}}{2 \ \times \ 0.01} \\\\a = 1.457 \ \times \ 10^{15} \ m/s^2

Therefore, the acceleration of the electron is 1.457 x 10¹⁵ m/s².

Which question could Not be answered by using the scientific method?
Alchen [17]
For the first question you could devise a way to test the question to find the answer. You could create a sample of black cats, a sample of white cats, and a control sample of a both black and white cats. 
<span>You would measure how much the cats eat each day. The study could be repeated or reviewed by your peers. </span>

<span>For the second question, there is currently no way to sample a person's thoughts, but even if there was a way, there would be no way to repeat the moment. It is not testable and not repeatable and thus cannot use the scientific method. </span>

<span>Calories can be measured and compared. </span>

<span>The tide can be observed until someone hypothesizes the right testable notion to determine the answer.</span>

lions [1.4K]

Answer:

748 treats.

Explanation:

If the trainer gives out 34 treats and gave them out for 22 shows, then to find the total you need to multiply 34 by 22, or (a longer but more simple way) add 34, 22 times.
