Answer:first of all what is your question and i can give and example which is Use them when you have 2 forces named Fa & FF or Fg & Ff acting in opposite directions on an object and you need to know the resultant of your 2 forces.
Explanation:
i searched it up
Answer:
D. Graphing the force as a function of distance and calculating the area under the curve.
Explanation:
Answer:
By the use of the reaction force one body is able to accelerate because it is not fixed to a rigid support which offers a materialistic resistance.
Explanation:
For every force there is an equal and opposite reaction is stated in the Newton's third law of motion holds true universally.
This law accounts for the acceleration of the bodies with respect to the object that applies force on the other body. The acceleration is possible when iether one of the body is fixed and cannot move or when that both the bodies are not fixed can move.
- For example consider a rocket with its engine started. This rocket generates upthrust by conversion of chemical energy of the fuel into the mechanical energy applying force on the launchpad. When this force is large enough it to lift the rocket then the rocket starts moving in the air and it accelerates. Now, when it is in the air or in vacuum during the course of its journey it uses the reaction of the burnt gases of the fuel to change the momentum.
This is in accordance with the Newton's second law of motion, stating that the Force is directly proportional to the rate of change in momentum.
Answer:
a
The magnitude of the force is 
The direction is from south to north i.e upward
b
The magnitude of the force is 
The direction is towards the west
c
The magnitude of the force is 
the direction of the magnetic field is parallel to the direction of the current (south to north ) hence the direction in 0 in comparison to the direction of the current
d
From the value of force we got the answer to this question is No
Explanation:
Generally magnetic force is mathematically represented as

Where the B is the magnitude of the magnetic field which is given as

is the current with a value of 
L is the length of the wire given as 
Substituting the value


For the first case where the current is moving from west to east and we are told that the magnetic field is from south to north the according to Fleming's right hand rule the force(exerted by earths magnetic field ) would be moving from south to north (i.e upward)
For the second case where current is moving vertically upwards the direction of the force is to the west according to Fleming's right hand rule
