The required force to do the same amount of work. 2. Fill in the blank. When using a wrench if you double the length of the wrench (effort arm), you have
doubled
tripled
halved
Quartered

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

answer a fan shaped mass of sediment deposited at the base of a mountain front do to an abrupt change in stream gradient;

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
