Answer:
It will be the second one.
Explanation:
The reason it is the second one is because it is bound by two spherical surfaces bulging outwards. The second is doing just that.
A convex lens is shaped like two half circles, with a thin edge and a thick centre. The second lens is a convex lens.
What is a convex lens?A convex lens has a thin edge and a thick centre and is shaped like two half circles. Convex lenses are converging and can produce virtual and real images. Light is bent inward by a converging lens, causing light rays to collide and form an image.
The convex lens is a lens that converges light rays that are parallel to its principal axis (i.e. converges incident rays towards the principal axis) and is relatively thick in the centre and thin at the lower and upper edges.
The edges are curved outward, not inward. It is used in front of the eye to sharply bend incoming light, causing the focal point to shorten and the light to focus properly on the retina.

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.
Answers
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

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
Answers
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

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
Answers
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!

What is solar radiation?Solar radiation, often called the solar resource or just sunlight, is a general term for the electromagnetic radiation emitted by the sun.
Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies

Explain why the temperature varies with distance from the Sun in this way?
Answers
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.

Which nucleus completes the following equation?
Answers
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
