What are some challenges of scuba diving

There are lots of challenges! You must always be careful and watch your oxygen level and nitrogen levels. There is always a chance of getting lost and not being able to find the boat again (even with your buddy), but if you have a diving buddy who is good about that they can teach you. Another thing is the thermoclines, sometimes you will wear a shorty and expect it to e perfect temperature and bam, its either too cod or too hot. There's also dangerous sea creatures, but as long as you can identify and avoid them you should be fine. Also sometimes the pressure can be a bit annoying but there are ways to equalize so u should be good. Good outways all the challenges though, in the end it's worth it!

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

force tends to be low and long diustance masses are high
