Peter weighs 100 pounds. He ran up a 6 foot hill in 2 seconds. What was Peter's power output? A. 1,200 ft-lbs./sec
B. 600 ft-lbs./sec
C. 300 ft-lbs./sec
D. 100 ft-lb/sec

300lb-ft/secs

Explanation:

Given parameters:

Weight of Peter = 100lb

Height of hill  = 6ft

Time taken  = 2s

Unknown:

Power output of Peter  = ?

Solution:

Power is the rate at which work is being done. It is expressed as;

     Power  =  

Work done  = force x distance = weight x height = 100lb x 6ft

 Work done  = 600lb-ft

   Power  =   = 300lb-ft/secs

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
