A laser emitting light with a wavelength of 560 nm is directed at a single slit, producing an interference pattern on a screen that is 3.0 m away. The central maximum is 5.0 cm wide. determine the width of the slit and the distance between adjacent maxima. attempt i used this equation...

I want to know what kind of manipulations can be done to decrease the distance between fringes. the activity is done with a laser. I am basing my conclusions on this equation delta x= (L)(lambda)/d here's what i am thinking, decreasing the wavelengths will decrease the distance...

two frictionless pucks are placed on a level surface, as shown, at an initial distance of 20.0 m. the mass of puck 1 is 0.80 kg and it has a charge of +3.0 X 10^-4 C., while puck 2 is 0.40 kg with a charge of +3.0 X 10^-4 C. the initial velocity of puck 1 is 12.0 m/s (E) and the initial velocity...

thanks everyone sooo much

thanks..i just want someone to clarify something..does the mass of the object not matter? if so, why not?

i used the mass of the meteor and i think i should have used the mass of earth?

i used the formula and got a negative value?

thanks a lot!

would this be correct? gh = GM / (R + h )2

not at all...where did i go wrong?

a 500 kg satellite experiences a gravitational force of 3000 N, while moving in a circular orbit around the earth. a: find the radius of the circular orbit b: find the speed of the satellite c: find the period of the orbit attempt a: g= GM/r^2 r=sqrt(GM/g) r= 3.33 x 10^-6 m am i...

a 12 kg meteor experiences an acceleration if 7.2 m/s^2. when falling towards the earth a: how high above the the Earth's surface is the meteor? b: what force will a 30 kg meteor experience at the same altitude? attempt: i'm, not sure which equation to use..would it be v= sqrt(Gm/r)?

i was thinking i should subtract the values because the rocket is in the middle and since gravity attracts and doesn't repel. is that anywhere near logical?

the Earth has a mass of 5.98 x 10^24 kg and the moon has a mass of 7.35 x 10^22 kg. the distance from the centre of the moon to the centre of the Earth is 3.84 x 10^8m. a rocket with a total mass of 1200kg is 3.0 x 10^8 m from the centre of the Earth and directly in between the Earth and the...

it's for magnetic force
