Answer:
Explanation:
The forces acting on a conductor carrying current placed in a magnetic field is analysed using the Fleming's left hand rule.
The rule states that "If the fire finger, the middle finger and the thumb are held mutually perpendicular to one another in a magnetic field, the fore finger acts in the direction of the magnetic field, the middle finger acts on the direction of the current while the thumb acts in the direction of the force.
Based on the rule, it can be inferred this current carrying wire placed in the magnetic field acts perpendicular to the magnetic field and force acting on the wire.
This is TRUE everything has a action the force from your feet pushes and the floor pushes back
Answer:
1. Equal.
Explanation:
Newton's third law of motion;
According to this law every action have its reaction with same magnitude but in the opposite direction.
If we push a wall with some amount of force then wall pushes back with same magnitude but in the opposite direction.This law tell us about action and reaction forces which are in same magnitude but in the opposite direction.
Therefore the answer will be 1.
1. Equal.
Answer:
intensity
Explanation:
The intensity of sound is a measure of how much <em>energy is flowing (through a unit area in which is perpendicular to the direction of the sound) per unit time.</em>
Its unit are micro joules per second per square cm. or watt per square cm.
watt is the unit of power and is gotten by the fact that power is the rate of doing work. so, p=E/t . The italicized text above (energy per unit time) can be replaced by power,p.
