2mm.
0,4x 5x10^6 = 2x10^6
1nm = 1x10^-6mm
2x10^6nm = 2mm.

RUDIKE [14]

Answer:

<em>d. The sail should be reflective because in this case the momentum transferred to the sail per unit area per unit time is larger than for absorbing sail, therefore the radiation pressure is larger for the reflective sail.</em>

<em></em>

Explanation:

Let us take the momentum of a photon unit as u

we know that the rate of change of momentum is proportional to the force exerted.

For a absorbing surface, the photon is absorbed, therefore the final momentum is zero. From this we can say that

F = (u - 0)/t = u/t

for a unit time, the force is proportional to the momentum of the wave due to its energy density. Therefore,

F = u

For a reflecting surface, the momentum of the wave strikes the sail and changes direction. Since we know that the speed of light does not change, then the force is proportional to

F = (u - (-u))/t = 2u/t

just as the we did above, it becomes

F = 2u.

From this we can see that the force for a reflective sail is twice of that for an absorbing sail, and we know that the pressure is proportional to the force for a given area. From these, we conclude that <em>the sail should be reflective because in this case the momentum transferred to the sail per unit area per unit time is larger than for absorbing sail, therefore the radiation pressure is larger for the reflective sail.</em>

What is the difference between electric force and electricity
FromTheMoon [43]

Answer:

Electrostatic force is force between two charges separated by distance in space while gravitational force is the force between two masses separated by a distance. Electrostatic force is either repulsive or attractive while gravitational force is always attractive

GaryK [48]

Answer:

The formula for force according to Newton's second law of motion is F=ma or force for an object to move is equal to mass times acceleration.

Acceleration or average acceleration defined as change in velocity per time.

F=ma

F=1.2x10³kg*(20m/s)(1/5s)=4.8x10³  Newtons
