A photon of wavelength 3.7 nm Compton scatters from an electron at an angle of 90°. What is the modified wavelength? (Enter your

viva [34]

Answer:

3.70242 nm

Explanation:

Using Compton effect formula

Δλ = ( h / mec) ( 1 - cosθ)

where h is planck constant = 6.62607 × 10 ⁻³⁴ m²kg/s

me, mass of an electron = 9.11 × 10⁻³¹ kg

c is the speed of light = 3 × 10⁸ m/s

Δλ = 6.62607 × 10 ⁻³⁴ m²kg/s / (9.11 × 10⁻³¹ kg × 3 × 10⁸ m/s ) ( 1 - cos 90°) = 0.242 × 10 ⁻¹¹ m = 2.42 × 10⁻¹² m = 0.00242 nm

modified wavelength = 3.7 nm + 0.00242 nm = 3.70242 nm

The distance between two planets is 1600 km. How much time would the light

Snowcat [4.5K]

Answer:

5.33*10^-3 seconds

Explanation:

c = d/t

c = speed of light constant (3.0*10^5 km/s)

d = distance (1600 km)

t = ?

3.0*10^5 = 1600/t

t = 1600/3.0*10^5

t = 5.33*10^-3 seconds

I hope this helped! :)

The capacitance of a capacitor depends on what?

bonufazy [111]

Answer:

The capacitance of a capacitor depends on the charge and voltage of a system. It is also dependent, if present, on the dielectric as well.

General Formulas and Concepts:
Gauss's Law

Capacitance Formula: $\displaystyle C = \frac{Q}{V}$

Q denotes charge
V denotes voltage

Dielectric Capacitance Formula: $\displaystyle C = \kappa C_0$

C₀ denotes original capacitance
κ denotes the dialectic constant

Explanation:

A capacitor stores charge when run through an electrical current. The capacitance is how much charge a capacitor can hold.

We can define the relationship of capacitance by using the formula. Capacitance is inversely proportional to the potential energy, or voltage, of the system. Therefore, you will need to know what the charge Q of the system as well has voltage V in order to find the capacitance.

If there is a dielectric involved inside the capacitance, you also must incorporate the value of the dielectric constant into your capacitance. A dielectric is directly proportional to the capacitance; the bigger the dielectric constant, the bigger capacitance, as denoted in our equation.

An inclined plane has a ramp length of 4.0 meters and a height of 2.0 meters. What is the IMA of the inclined plane? 0.5 2.0 6.0

Aleonysh [2.5K]

Length of the ramp (L) = 4.0 m = Distance traveled by the effort

Height of the inclined plane (h) = 2.0 m = Distance traveled by the resistance

IMA = Ideal mechanical advantage

$IMA = \frac{L}{h}$

$IMA = \frac{4.0}{2.0}$

IMA = 2.0

Hence, the IMA of the inclined plane is 2.0

the smallest unit in physics is the Planet length.wr need to know constant (h) the speed of light (c) and Newton's Gravitational

fgiga [73]

Yes, that's right. It's the 'Planck' length, not the 'Planet' length.

You could easily find these with a web search. But in gratitude
for the bountiful 5 points, I've saved you the trouble.
AND guess what !   By doing that, I learned something, and
you didn't.

Speed of light (c):    299,792,458 meters per second

Gravitational constant (G): 6.67 x 10⁻¹¹ newton-meter²/kilogram²

Planck's Konstant (h):   6.63 x 10⁻³⁴ joule-second

Planck Length:    1.6 x 10⁻³⁵ meter
(about 10⁻²⁰ the size of a proton)

Planck Time:    10⁻⁴³ second
   (about the time it takes to travel
a Planck Length at the speed of light)
