iPad 10:04 AM 81 % 10. Which one of the following is the correct formula for centripetal force (which, as a force, should be in units of newtons). [m is in kg, v is in m/s, ris in m] 3 of 4 a) (b) V mvr 11. Fill in the blanks (a) 10 millipedes is a (b) A trillion microphones is a (c) 10 cards is a cover of textbook.] See metric table near front 12. (a) Convert 200 mi/h to m/s. (b) Convert 100 W to hp and to ft.lb/s. Convert 21.5 km's to%per bilion years. MLY is mega-lightyears.] 13. A student proves that a dollar equals a penny as follows: A dime is both one-tenth of a dollar and equal to 10 cents 1$ 10 Square both sides, will still be equal But 01S1 and 100 1S so What's wrong with this argument? 01$ 100p 14. Rusty's is offering a special price of $15 for their large (20) pizza (regular price $18). They also sell small (10") pizzas for a price of $5. Two hungry CSUB students arrive... Raphael: "A special deal, great! Let's get a large one. Donatello: "Don't be dumb. Let's get three of the small ones for the same price. More pizza and cheaper. Raphael: "They wouldn't sell less for more and call it a special, let's get the large." Who's right? What if they were square pan pizzas?Explanation / Answer
10) (b)mv^2/r
centripital force is given by:
F = ma
a = v^2/r ;
F = m v^2/r
11)(a)10 millipedes is a 1 centipede
(b)a trillion microphone is a 1 megaphone.
(c)
12)(a)200 mi/h to m/s
1 mi/h = 0.447 m/s
220 mi/h = 98.35 m/s
b)1 W
1 W = 0.0013 HP ; 1 ft lb/s = 1.36 W
100 W = 0.13 HP
100 W = 73.53 ft lb/s
