False because the physics is like a science and it’s like a math
effort distance =?
effort =100N
load =300N
lever =1m
load D =30cm
ma=?
vr=?
efficiency =?
we know that
effort distance =l ×ld
= 300×30
9000
ma= l ×e
= 100×300
= 30000
vr = ld ×ed
= 1×9000
=9000
efficiency =(ma÷vr)/100
(30000÷9000)×100
3.33×100
333
