Plants may get yellow if they get less nitrogen.give reasons.

Vaselesa [24]

Explanation:

Nutrient deficiency causes yellowing of leaves. One of such nutrient is Nitrogen.

Leaves are green because of a pigment in them called chlorophyll.
The chlorophyll in leaves are used by plant to absorb light energy needed for photosynthesis.
Other wavelength of light is absorbed by the chlorophyll and the green color is reflected.
Nitrogen is an important nutrient that is needed to produce chlorophyll in plants which in turn helps the process of photosynthesis.

Extra CreditA particle is directed along the axis of the instrument in the gure. Aparallel plate capacitor sets up an electric e

kvv77 [185]

This question is incomplete, the complete question is;

A particle is directed along the axis of the instrument in the figure below. A parallel plate capacitor sets up an electric field E, which is oriented perpendicular to a uniform magnetic field B. If the plates are separated by d = 2.0 mm and the value of the magnetic field is B = 0.60T.

Calculate the potential difference, between the capacitor plates, required to allow a particle with speed v = 5.0 × 10⁵ m/s to pass straight through without deflection.

Answer:

the required potential difference, between the capacitor plates is 600 V

Explanation:

Given the data in the question;

B = 0.60 T

d = 2.0 mm = 0.002 m

v = 5.0 × 10⁵ m/s.

since particle pass straight through without deflection.

F $_{net$ = 0

so, F $_E$ = F $_B$

qE = qvB

divide both sides by q

E = vB

we substitute

E = (5.0 × 10⁵) × 0.6

E = 300000 N/C

given that; potential difference ΔV = Ed

we substitute

ΔV = 300000 × 0.002

ΔV = 600 V

Therefore, the required potential difference, between the capacitor plates is 600 V

A laser emitting light with a wavelength of 560 nm is directed at a single slit, producing an interference pattern on a screen t

muminat

Answer:

a) a = 6.72 10⁻⁵ m, b) the slit (a) is smaller, which represents a wider pattern

Explanation:

In is a diffraction experiment since we have a single slit, it is explained by the equation

a sin θ = m λ

where a is the width of the slit

The diffraction pattern is characterized by a very intense central maximum, with a value of 5.0 cm, therefore the distance from the center to the first zero is y = 5.0 / 2 cm = 2.5 10⁻² m

let's use trigonometry to enter the angle

tan θ = y / L

tan θ = sin θ / cos θ = sin θ

sin θ = y / L

substituting into the equation

a y / L = m λ

the first maximum occurs for m = 1

a = λ L / y

let's calculate

a = 560 10⁻⁹ 3.0 / 2.5 10⁻²

a = 6.72 10⁻⁵ m

b) if the width a of the slit (a) is smaller

sin θ = m λ / a

therefore the sinus increases, which implies a greater angle, which represents a wider pattern

c) if the distance to the screen (L) goes away

y = m λL / a

If L increases the width of the pattern they also increase of course the intensity must be less

d) If the wavelength increases

In this case the width of the pattern also increases

e) What happens if the light passes through two slits in this case we have two diffraction patterns one centered in each slit and the resulting pattern is the sum of these patterns, this sum gives the double slit interference that characterizes a series of slits of equal height

A guitar string is 1.75 m. Calculate the wavelength of the 78th harmonic *

bulgar [2K]

Answer:

0.04 m

Explanation:

The harmonic is given by λ = 2L/n were L= length of guitar string = 1.75 m and n = harmonic = 78.

So, λ = 2L/n = λ = 2 × 1.75 m/78 = 0.044 m ≅ 0.04 m
