Explanation:
Use trigonometry. The horizontal force is:
Fₓ = F cos θ
Fₓ = 20 N cos 60°
Fₓ = 10 N

Answer:
Cause and effect
Explanation:
In this text, the most suitable structure is a cause and effect structure. The text explains why the prices of economy cars rose substantially in the United States during the mid-1980s. The initial cause was import quotas, which led to the effect of the Japanese sending mostly luxury cars to America. This pattern is reproduced through the passage, allowing us to understand the connection between different sentences within a paragraph.
Answer:
b. Transfer pipets; more accurate; measuring pipets.
Explanation:
Transfer pipets can be defined as an ungraduated or graduated disposable plastic instrument which are typically used in science laboratories to transfer or deliver liquids that are small in volume (microliters) . Also, they are generally being referred to as chemical
droppers, teat pipets, eye droppers, pasteur pipets, or droppers. It is made up of an ultra-clear long, slender tube with low density polyethylene (LDPE) and an integral molded bulb. The molded bulb allows a fixed volume of the desired liquid to be dispensed (transfered) or aspirated through compression and relaxation.
Hence, transfer pipets are calibrated to deliver one fixed volume and are more accurate than measuring pipets because of its long, slender tube which limits errors.
