HELP ASAP! 1. Why do you think it is important for people to know when the tides will be high and/or low?

Many reasons. Here are a couple:

1.) Water depth for the draft of incoming ships/vessels so they do not run aground.

2.) Distance between sea level and bottom of structures such as bridges for vessels passing underneath.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
