Question

b) Let them not be called, change a voice​

Answer 1

Answer:

Given that,

Force F=50N

Mass M=10kg

μ=0.1

Now, the net force is

F

n

=F−μmg

Now, the work done is

W

net

=(F−μmg)×s

W

net

=(50−0.1×10×10)×5

W

net

=250−50

W

net

=200J

Hence, the work done is 200 J

Answer 2

Answer:

The structure of converting the imperative sentences to passive form, starting with ‘Let’, is as follows -

Let + object of the active sentence + be + main verb’s 3 rd form also known as past participle + preposition “by” + same pronoun with which the active sentence began (here in this case it is ‘them’)

So the passive sentence would be -

Let the responsibility of completing the project be taken by them
