Aposition vector with magnitude 10 m points to the right and up. its x-component is 6.0 m. part a what is the value of its y-component?

The position vector can be transcribed as:

A = 6 i + y j                           

i points in the x-direction and j points in the y-direction.

The magnitude of the vector is its dot product with itself:

|A|2 = A·A

102  = (6 i + y j)•(6 i+ y j)            Note that i•j = 0, and  i•i  = j•j = 1 

100  = 36 + y2       

64    = y2

get the square root of 64 = 8

The vertical component of the vector is 8 cm.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
