Its either b or d, most likely d
Answer:
0.48 cm
Explanation:
given data
wavelength = 480 nm
wavelength = 560 nm
slit spacing = 0.040 mm
distance between double slits and the screen = 1.2 m
solution
we know that (1 nm= 
m)
we wil take here equation of equations of interference that is
ym = R × (m λ)/d ..........................1
here m = 2 R i.e distance of screen and slit
so put here value and we get
separation between the second-order bright fringes = 0.48 cm
Yes, this is because particles in a solid there are more particles which are touching. They can only vibrate. But particles in a gas are far apart. This is the same for liquids to.
Answer:
T=1263.16N
Explanation:
A 958-N rocket is coming in for a vertical landing. It starts with a downward speed of 25 m/s and must reduce its speed to 0m/s in 8.0 seconds for the final landing. During this landing maneuver, what must be the thrust due to the rockets engines?
force is that which tends to cane a body state of rest or uniform motion in a straight line
it is also the pull or pus on an object.
the forces involved here to get the thrust on an object, are the weight and the force of gravity
W=mg
958=m*9.81
m=958/9.81
m=97.655kg
T=m(g+a)................................1
to get a
v=u+at
a=dv/dt
a=25/8
a=3.125m/s^2
acceleration is change in velocity per time
juxtaposing into the equation 1
T=97.655(9.81+3.125)
T=1263.16N
To answer the problem we would be using this formula which isE = hc/L where E is the energy, h is Planck's constant, c is the speed of light and L is the wavelength
L = hc/E = 4.136×10−15 eV·s (2.998x10^8 m/s)/10^4 eV
= 1.240x10^-10 m
= 1.240x10^-1 nm
