How much energy will an electron gain if it moves through a potential difference of 1.0 V?

Physics
1 answer:
Setler [38]3 years ago
6 0

Answer:

a. 1.0 eV

Explanation:

Given that

Voltage difference ,ΔV = 1 V

From work power energy

Work =Change in the kinetic energy

We know that work on the charge W= q ΔV

For electron ,e= 1.6 x 10⁻¹⁹ C

q=e= 1 x 1.6 x 10⁻¹⁹ C

Change in the kinetic energy

ΔKE= q ΔV

Now by putting the values

ΔKE=  1 x 1.6 x 10⁻¹⁹   x 1   C.V

We can also say that

ΔKE=  1 e.V

Therefore the answer will be a.

a). 1.0 eV

In which situation is maximum work considered to be done by a force?
umka2103 [35]

Answer:

A) When the angle between the Force (F) and Displacement (x) is 0°, because, Work done (W) is directly proportional to the Cosine of the Angle between the Force applied and the resultant displacement of the subject.

W = F•x cos ∅

If ∅ = 0°,

W = F•x ===> Maximum Work Done.

If ∅ = 45°,

W = F•x/√2

If ∅ = 90°,

W = 0

If ∅ = 180°,

W = –F•x ===> Minimum Work Done.

Three collinear forces,F1=45N west,F2=63N east and an unknown force F3 are applied to an object.The resultant force of the three
Greeley [361]

Take east to be the positive direction. Then the resultant force from adding <em>F</em>₁ and <em>F</em>₂ is

<em>F</em>₁ + <em>F</em>₂ = (-45 N) + 63 N = 18 N

which is positive, so it's directed east.

To this we add a third force <em>F</em>₃ such that the resultant is 12 N pointing west, making it negative, so that

18 N + <em>F</em>₃ = -12 N

<em>F</em>₃ = -30 N

So <em>F</em>₃ has a magnitude of 30 N and points west.

How many significant digits should the answer to the following problem have? (2.49303 g) * (2.59 g) / (7.492 g) =
Feliz [49]

The number of significant digits to the answer of the following problem is four.

<h3>What are the significant digits?</h3>

The number of digits rounded to the approximate integer values are called the significant digits.

The following problem is

(2.49303 g) * (2.59 g) / (7.492 g) =

On solving we get

= 0.86184566204

The answer is approximated to  0.86185

Thus, the significant digits must be four.
