10.The centripetal force F in newtons exerted on a passenger by a spinning amusement park ride and the number of seconds t the ride takes to complete
one revolution are related by the following equation:
t = V([1620 ]/F)
Find the centripetal force experienced by this person if t = 10; round your
answer to the nearest hundredth

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

answer: #1 ads up by 8 and i don't know #2

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
