Which of these measures a wavelength.

Answer:

Option D. ⁸⁵₃₆Kr

Explanation:

⁸⁵₃₅Br —> ⁰₋₁e + ?

Let ⁿₘZ represent the unknown.

Thus, the equation becomes:

⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ

Next, we shall determine n, m and Z as follow:

85 = 0 + n

85 = n

Thus,

n = 85

35 = –1 + m

Collect like terms

35 + 1 = m

36 = m

Thus,

m = 36

ⁿₘZ => ⁸⁵₃₆Z = > ⁸⁵₃₆Kr

Thus, the equation:

⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ

Becomes:

⁸⁵₃₅Br —> ⁰₋₁e + ⁸⁵₃₆Kr

Answer:

At infinity the image is formed

When a lens produces light rays that are parallel, the image is: C. non-existent.

A ray diagram can be defined as the graphical representation of the possible paths light takes from one point (source) to another.

Hence, a ray diagram is a graphical representation of how light interacts with a boundary, so as to help us view a point on the image of an object.

Basically, the characteristics of an image produced from a lens or mirror can be determined by drawing a ray diagram of the possible paths taken by light.

On a ray diagram, an image produced from a lens is non-existent when the lens produces light rays that are parallel because the refracted rays of light neither diverge nor converge.

In conclusion, an image cannot be formed (non-existent) when a lens produces light rays that are parallel, due to refraction.

Answer:

noise pollution

Explanation:

Visual pollution may be defined as a pollution that obstructs a view. It impairs one ability to see and enjoy a pleasant view. It is considered as an aesthetic issue.

The rotating blades of the windmill causes visual disturbances by intercepting the light of the sun and it causes moving shadows and the light flashes from the reflection of the sun. It also causes noise or sound as the blades rotates. Thus the combination of visual and acoustics exposures leads to the negative assessment of the windmills.

Therefore, people living near wind farms objects the windmills as they causes visual pollution as well as noise pollution.

Answer:

Volume = 5 cm³

Explanation:

Given the following data;

Density = 22.6 g/cm³

Mass = 113 grams

To find the volume;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the equation;

[tex]Density = \frac{mass}{volume}[/tex]

Making volume the subject of formula, we have;

[tex]Volume = \frac{mass}{density}[/tex]

Substituting into the equation, we have:

[tex]Volume = \frac{113}{22.6}[/tex]

Volume = 5 cm³

Answer:

I think its 1

Explanation:

The reason why I think it's 1 is because 0.5m/s^2 /0.5 m/s= 1 s

Answer:

Suppose at time t1 = zero and v1 = 50 MPH

                    time t2 = 10 sec and v2 = 10 MPH

Change in speed   =  (v2 - v1) / (t2 - t1) = (10 - 50) MPH / (10 - 0) sec

Change in speed = -40 MPH / 10 sec = - 4 MPH / sec

If you specify the velocity as always East then

change in velocity = - 4 MPH East

Had the particle finished by moving in the Westerly direction  then

Change in velocity = (-10 - 50) MPH / 10 sec = -60 / 10 MPH = -60 MPH East

Where West was the positive direction

Initially v1 was 50 East and v2 was -10 East with a difference of 60 MPH

Answer:

182 V

Explanation:

We do:V=I.R

V is energy so

I = 7

R = 7+7+3+3+6

V= 7.26

V=182

Explanation:

1) velocity = displacement/time

time = displacement/velocity

time = 200/660

= 10/33

= 0.303

2) vf = vi - a*t

0 = 30 - 9.8*t

t = 30 ÷ 9.8

t = 3.06 seconds

Answer:

2.67×10² m

Explanation:

Applying

V = λf............... Equation 1

Where V = Velocity of radio wave, λ = wave length, f = frequency.

make λ the subject of the equation

λ = V/f................ Equation 2

From the question,

Given: V = 2.99×10⁸ m/s, f = 1.12×10⁶ Hz.

Substitute these values into equation 2

λ = (2.99×10⁸)/(1.12×10⁶)

λ = 2.66696×10² m

λ ≈ 2.67×10² m
