wouldn't it be 1000 km/h considering the plane was travelling the same speed for over half the trip?
A. An object in motion will remain in motion unless acted upon by an outside force : The momentum of an object is constant unless an outside force acts on the object.
B. Force is defined as mass times acceleration : the rate of change of the momentum of a particle is proportional to the force F acting on it, hence the force is equal to <span>mass times acceleration.
C. </span>For every action there is an equal and opposite reaction : <span>to every action force there is an equal and opposite reaction force. </span>
Answer:
Explanation:
Given
mass of block resting on wedge is
mass of block hanging vertically is m
coefficient of static friction
Let T be the tension in rope
thus for Equilibrium T=mg
is friction force
substitute the value of T
Also
Direction of Friction can either be directing upward or downward depending upon which side system goes after it is released from equilibrium or about to release.
an animal that feeds on carrion, dead plant material, or refuse
Answer:
The correct option is 'D': Equal and opposite force.
Explanation:
We know from Newton's third law of motion
"For every action there exists an equal and opposite reaction".
The statement is further explained as
If there exists a force from Body 1 to Body 2 then Body 2 must also exert an equal and opposite force on the Body 1.
In simple terms we can say that the action and the reaction forces exist in pairs and are always present if any one among them is present.
