B.the light of the laser pointer lights up a larger area of the paper
C.the light from the flashlight magnifies the larger area of paper D.the light from the laser pointer magnifies a larger area of the paper
Answers
Answer:
the answer is A
Explanation:
The light from the flashlight lights up a larger area from the paper.
What is laser point?Lasers provide very directional light. A fairly thin beam of laser light is directed in a particular direction. Conventional light is released in numerous directions away from the source, whether it is the sun, a lightbulb, or a candle.
The simplest way to spruce up any landscape or light up your house for the holidays is with a laser light projector.
Every price range and occasion can find the perfect laser light show projector. Both indoor and outdoor beautiful lighting displays can be made with them.

Answer:
2.25 : 1
or 9 : 4
Explanation:
\(q_1 = \frac{1}{2}nv_1^2 \\\\q_2 = \frac{1}{2}nv_2^2\\\\\\)
Given
v₁ = v
v₂ = 1.5v
Since v₂ > v₁, q₂ is the dynamic pressure of the faster fluid
The ratio is
\(\frac{q_2}{q_1} = \frac{\frac{1}{2}nv_2^2 }{\frac{1}{2}nv_1^2}\\ \\=\frac{v_2^2}{v_1^2}\\\\=\frac{(1.5v)^2}{v^2} \\\\=\frac{1.5^2*v^2}{v^2} \\\\= 1.5^2\\\\=2.25\)
2.25 : 1
or 9 : 4
Answer:
q=12nv2. The dynamic pressure q generated by a fluid moving with velocity v can be found using the formula above, where n is the constant density of the fluid. An aeronautical engineer uses the formula to find the dynamic pressure of a fluid moving with velocity v and the same fluid moving with velocity 1.5v.

The area of the circles will be 314 meters² and 113 yards².
How to calculate the area?It should be noted that the area of a shape simply means the total space that is taken by the shape. It simply expresses the extent of the region on a particular plane as well as a curved surface.
In this case, the area of the first circle will be:
= πr²
= 3.14 × 10²
= 314 meters²

Answers
Answer:
for me i do mapping and outlining and i describe ideas as i go on
Explanation:
Mapping and outlining are brainstorming techniques. Hence, option D and E are correct.
What is Mapping?Word mapping is the process of saying a word, breaking it down into phonemes, writing the letter combinations that make each sound, and then writing the word as a whole. Through this process, students gain a comprehension of and an opportunity to apply the phonemic and graphical skills needed for each word.
Maps give clear, observable information about the world. To teach about it, they use examples of the sizes and shapes of the world's countries, the locations of its features, and the distances between regions. Maps can show patterns of colonization as well as the distribution of different objects around the world.
Data mapping is the process of linking a data field from one source to a data field in another source. As a result, there is a lesser chance of errors, your data is more uniform.
Thus, option D and E are correct.

Why do you think business owners had the support of the police or state militia in several strikes ?
Answers
Answer:

Explian the the process of wind erosion versus water erosion and the effects they each have on soil.
Answers
Wind erosion damages the soil by physically removing the most fertile part, lowering water-holding capacity, degrading soil structure, and increasing soil variability across a field, resulting in reduced crop production. It tends to remove silts and clays making the soils sandier.
Erosion breaks down soil structure, exposing organic matter within soil aggregates to decomposition and loss. Degraded soil structure reduces the rate of water infiltration
Differences in atmospheric pressure will cause the motion of air that can erode surface material when velocities are high enough to move particles.
Eolian erosion is more pronounced in dry regions and in areas where there is insufficient rainfall to support vegetation and root systems.
Wind cannot carry as large particles as flowing water, but easily pick ups dry particles of soil, sand and dust and carries them away.
Wind generally causes erosion by deflation and/or abrasion.
Wind breaks are often planted by farmers to reduce wind erosion.
