Ray diagrams may be drawn to determine the characteristics of an image produced from a lens or mirror. When the lens produces light rays that are parallel, the image is
Question 16 options:

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.

HOW DOES A GRAPH HELP YOU SEE ANOMALOUS DATA?
Answer:
Anomalies consist of one or more modifications, insertions or deletions. As was described in Section 3.1, there are only three types of changes that can be made to a graph. Therefore, anomalies that consist of structural changes to a graph must consist of one of these types. Assumption 4.

A 57 kg ice skater moving to the right with a velocity of 1.2 m/s throws a 0.11 kg snowball to the right with a velocity of 31.5 m/s relative to the ground. What is the velocity of the ice skater after throwing the snowball? Disregard the friction between the skates and the ice.
Answer:
v_f = 1.14 m / s
Explanation:
This is an exercise of conservation of momentum, let's define a system formed by the skater and the snowball, therefore the forces during the launch are internal and the moment is conserved.
Initial instant. Before throwing the ball
p₀ = M v₀
Final moment. After throwing the snowball
p_f = (M-m) v_f + m v
the moment is preserved
p₀ = p_f
M v₀ = (M-m) v_f + m v
v_f = [tex]\frac{M v_o - m v}{M-m}[/tex]
let's calculate
v_f = [tex]\frac{57 \ 1.2 - 0.11 \ 31.5}{ 57 - 0.11}[/tex]
v_f = 64.936 / 56.89
v_f = 1.14 m / s
Which nucleus completes the following equation?
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

Explain why the temperature varies with distance from the Sun in this way?
Answer:
The average surface temperature decreases the further you get from the Sun because the more distant planets receive less energy/heat/sunlight per square meter of their surface. This is because the energy from the Sun spreads out (becomes less concentrated) as you travel further from the source/Sun.

A certain AM radio wave has a frequency of 1.12 x 106 Hz. Given that radio waves travel at 2.99 x 108 m/s, what is the wavelength of this radio wave? (Round your answer to three significant figures.) Answer in "m" units
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

7. Can the speed of a particle be negative? Can the
velocity of a particle be negative? Give arguments to
support your answers.
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

what effect does the earth's surface have on solar radiation?
A. The ground absorbs half the solar radiation and stored it as infrared radiation for centuries
B. Half of the solar radiation is absorbed and converted to infrared (heat)
C. Nearly all solar radiation is reflected back into space by the ground
Answer:
B.
Explanation:
Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere.
Hope this helps, sorry if it is incorrect. Have a great day/night!
