Answer:
the required minimum magnitude of the force F is 21 N
Explanation:
Given the data in the question,
m = 5 kg
width = 60 cm
height = 80 cm
Let force is F represent in the image below,
so when the block about to rotate normal shifted to edge of cube
mg(w/2) = Fh
F = mg(w/2) / h
we know that g = 9.8 m/s²
we substitute
F = (5 × 9.8 ( 60/2)) / 70
F = (5 × 9.8 × 30 ) / 70
F = 1470 / 70
F = 21 N
Therefore, the required minimum magnitude of the force F is 21 N
The center of gravity is a SIKKE bro you really thought I’d give the answer of something so simple
The answer should be speed hope this helps
Because the sound waves are being observed by the people that are there and it is not empty as in an empty place the sound waves will come back to you.
The given question is incomplete. The complete question is attached with an image below.
Explanation:
Mass flow rate through region A will be calculated as follows.
Rate = 
= 
= 
= 
Therefore, we can conclude that the mass flow rate through region A is .
