C

because formula for weight is mass of object (m) multiplied by gravitational acceleration (g).......if mass is 2m then weight will become 2mg.......there is no change in (g)......never

Answer: Option (C) is the correct answer.

Explanation:

The relation between mass and weight is as follows.

                 Weight = mass × g

where,    g= gravitational force = 9.81 m/s^{2}

For mass = 2m, calculate the weight as follows.

             Weight = mass × g

                          = 2m × g

                          = 2mg

This means that when mass of object becomes 2m then its weight will also become 2mg.

Therefore, we can conclude that if the weight of an object of mass "m" is "mg," then the weight of an object of mass "2m" is 2mg.

Lawson's criterion states that the product of ion density and confinement time must exceed a certain number before a break-even
LekaFEV [45]

According to Lawson's criterion, the outcome is determined by the product of ion density and confinement time because the temperature must be maintained for a sufficient confinement time and with a sufficient ion thickness to obtain a net gain of power from a fusion reaction.

<h3>What are Lawson's criterion?</h3>
  • The overall conditions that must be met in order to produce more energy than is required for plasma heating are usually expressed in terms of the product of ion density and confinement time, a condition known as Lawson's criterion.
  • In nuclear fusion devices, confinement time is defined as the amount of time the plasma is kept at a temperature above the critical ignition temperature.
  • Even at temperatures high enough to overcome the coulomb barrier to nuclear fusion, a critical density of ions must be maintained in order to achieve a net yield of energy from the reaction.
  • Because the density required for a net energy yield is correlated with the confinement time for hot plasma, the minimum condition for a productive fusion reaction is typically stated in terms of the product of ion density and confinement time, which is known as Lawson's criterion.

What is difference between non uniform and uniform circular motion?
statuscvo [17]

Answer:

The object in a uniform motion covers same distances in an equal time period. Objects in a non-uniform motion cover dissimilar distances in an equal time period.

Explanation:

The speed of the object traveling in uniform motion is constant, the actual speed and the average speed of the moving body is same.
