Answer:
Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.
Explanation:
The distance 
from the central band to the first bright band is given by
where 
is the wavelength of light (or any particle), 
is the distance to the screen, and 
is the slit separation.
From this equation we see that, by increasing the wavelength , increasing the distance from the screen , and decreasing the slit separation , we increase the distance between the first bright band and the central band.
Therefore, the 2nd choice "<em>Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.</em>" is correct.
Explanation:
mass of earth (m1)=5.97×10^24
mass of moon (m2)=7.35×10^22
distance between their center (d)= 3.84×10^8
G=6.67×10^-11
now,
gravitational force =(F)= G(m1×m2)/d²
- 6.67×10^-11(5.97×10^24×7.35×10^22)/(3.84×10^8)
- 19.84×10^19

Answer:
As we know that friction force always oppose the motion of body.In other words we can say that friction act opposite to the direction of motion of the body.It tries to stop the body is body is in motion.The value of friction force varies and reaches up to a maximum value.If the body is in rest condition then friction force will be static friction and the body is in moving position then the friction force will be kinetic friction.
Here given that we apply a force in the right direction then friction will act in the left direction.
