To move a resting box of 100 newton on the ground with kinetic friction coeficient of 0,250 is applied a force of 60 n horizontally and displacing it 10 m. how much work does applied force do? how much work is done against friction force? what is kinetic energy of the box?

as we know that in transformers we have

here we know that

now from above equation we will have

now we have to reduce this voltage to final voltage of v = 4 v

so again we will have

so we need to take such a winding whose ratio is 1: 5

so it is satisfied in x

so answer will be

b)-   x

scientific notation is given as

here we know that

1 <   a < 10 and

k = whole number

now the number will be

n = 299,790,000

here we know that

so we have

a = 2.99

k = 8

answer:

by its amplitude.

explanation:

loudness is sound intensity & intensity depends on square of amplitude. for example higher the amplitude higher the intensity which means higher the loudness.
