I’LL MARK YOU BRAINIEST IF U ANSWER IT A pulley system lifts a 500-N weight a distance of 1.5m. Marina pulls the rope A distance of 9.0m, exerting a Force of 100 N.

a) what is the mechanical advantage of this pulley system

b) What input did marina do on the road

c) what useful output did the rope do on the weight

d) what is the efficiency of the pulley system

THIS IS GRADE 8 PHYSICS PLEASE ANSWER

OMGGG PLEASE HELP IM LATE

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

did yall get answers for this yet

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
