A Proton with a Speed Of $2.0 \times 10 ^ { 5 } \mathrm {~m} / \mathrm { s }$

question 2

Multiple Choice

A proton with a speed of $2.0 \times 10 ^ { 5 } \mathrm {~m} / \mathrm { s }$ accelerates through a potential difference and thereby increases its speed to $4.0 \times 10 ^ { 5 } \mathrm {~m} / \mathrm { s }$ . Through what magnitude potential difference did the proton accelerate? $\left( e = 1.60 \times 10 ^ { - 19 } \mathrm { C } , m _ { \text {proton } } = 1.67 \times 10 ^ { - 27 } \mathrm {~kg} \right)$

• A) \(840 \mathrm {~V}\)
• B) \(1000 \mathrm {~V}\)
• C) \(100 \mathrm {~V}\)
• D) \(210 \mathrm {~V}\)
• E) \(630 \mathrm {~V}\)

The consumption of an excessive amount of alcohol in a short period, typically defined as five or more drinks for men and four or more for women within about two hours.

Statistical Probability

The likelihood or chance of an event occurring, based on a scale from 0 to 1, where 0 indicates impossibility and 1 indicates certainty.

Level of Significance

A statistical measure that determines the threshold at which the null hypothesis is rejected, often denoted by alpha (α).

Null Hypothesis

A statistical presumption positing that there is no notable difference or impact.
