Since static friction is the minimum force required to just start the motion of a stationary object.
Here if we need to start an object from rest then we required F = 700 N
So for the first part of the above problem Force will be F = 700 N
Now if the box is already moving then we will have to use kinetic friction force between box and floor
now we can write the equation of net force as
here
now we will have
Answer:
time taken is equal to 14,156 years
Explanation:
we know,
at t = 0
Y(0) = A
given that half life of plutonium 239 = 24,200
hence time taken is equal to 14,156 years
Answer:
You can drink 18 drinks and 1.38 dollars left with you.
Explanation:
1 drink cost 1.59 dollars
You have 30 dollars with you.
Number of drinks in 30 dollars =
Number of drinks in 30 dollars = 18
From division 1.36 remains as remainder so, 1.38 dollars left with you.
