According to Newton's Second Law of Motion, the net force experienced by the system is equal to the mass of the system in question times the acceleration in motion. In this case, the net force is the difference of gravitational force and the force experience by the motion of the airplane. This difference is already given to be 210 N.
Net force = ma
210 N = (73 kg)(a)
a = +2.92 m/s²
Thus, the acceleration of the airplane's motion is 2.92 m/s² to the positive direction which is upwards.
Answer:
option D.
Explanation:
The correct answer is option D.
At present the knowledge of physics does not includes the study related to souls , other spiritual substance.
Physics does not give the answers of question like God created universe , matter is unreal, etc.
So, there might will be possibility that in future complete physics will give the answer of all these questions i.e. correct answer is All of the above.
In most cases the temperature must increase for thermal expansion to occur. Most substances expand as temperature increases because the atoms or molecules vibrate faster as temperature increases and experience greater separation.
Answer:
The value is 
Explanation:
From the question we are told that
The mass of each sphere is 
The length of the string is 
The angle of with the vertical is 
The acceleration due to gravity is 
Generally the force acting between the forces is mathematically represented as
=> 
Generally from Pythagoras theorem the radius of the circular curve created by the force is
=> 
=> 
=> 
=> 
=>
