idk what they are related to

anonymous · Answer

oh so i just should give answers,ok

anonymous · Answer

W = F.d and it's for work

we say F.d so there should be a distance too,and the a,b and care just abould holding,sitting and etc, and there 's no distance so d is correct .

anonymous · Answer

Newton is for F and meters is for D and watts is for power,and joules is for work ;)

anonymous · Answer

W = F.d and d=5m and w = 60j so f = w/d = 60/5 = 12 n and the second one is correct :)

anonymous · Answer

can you explain the question number 7 ?

anonymous · Answer

sorry number 6!

anonymous · Answer

not 7

anonymous · Answer

c as june did it in a shorter time

anonymous · Answer

$$power = i v = \frac{ dq }{ dt } \frac{ dw }{ dq }= \frac{ dw }{ dt }$$
the rate change of wok done.
