Answer: kinetic energy is Energy of motion.
Explanation:
Answer:
Explanation:
According to the Fleming's right hand rule, if we spread our right hand such that the thumb, fore finger and the middle finger are mutually perpendicular to each other, then the thumb indicates the direction of force, fore finger indicates the direction of magnetic field, then the middle finger indicates the direction of induced current.
According to the Lenz's law, the direction of induced emf is such that it always opposes the cause due to which it is produced.

Answer:
Momentum (P)= 3.15Kg.m/s
Explanation:
Because momentum by definition is the product of mass and velocity, therefore, it's calculated by the formula;
P=mv,,,
where 'P' Is the momentum
'm' is mass in Kilograms, note that mass should be in Kilograms, therefore the 450grams should be converted to kilograms by dividing it with a 1000, i.e (450g×1kg/1000g)= 0.45kg, and now you can substitute in the formula because you have everything you need to find momentum in the right si units.
so P=mv
P=0.45Kg×7m/s
P=3.15Kg.m/s
