Answer:
I think the way to sure the building falls safely is by the engineers using too much force with a wrecking ball.
I have been busy so I hope this helps:) ily!!!! <333
Answer:
Magnitude of induced emf will be 
Explanation:
We have given radius of the circular loop r = 19.7 cm = 0.197 m
So area of the circular loop 
It is given that magnetic field is changing as 
Emf induced in the circular loop is equal to 
So emf induced will be equal to 
So magnitude of induced emf will be 
For the rest 3 km
Bholu need to run in 5 minutes so
He need to 3 × 1000 / 5 × 60 m/s
3000/ 300 = 10 m/s
So , his speed should be 1 m/s to reach in 5 minute

Answer: 0.6m
Explanation:
Given that:
force = 4.5 N
Work done = 2.7J
Distance moved by the book = ?
Since work is done when force is applied on an object over a distance, apply the formula:
work = force x distance
2.7J = 4.5N x distance
Distance = (2.7J / 4.5N)
Distance = 0.6 m
Thus, the book was moved 0.6 metres far
