Answer:
The split separation d = 2.12 * 10^-4 m
Explanation:
Mathematically, for a double split interference, the relation between separation of slit and fringe width is given by the formula;
d = Rλ/Δy
Where R represents the distance of screen from the slit given as 1.86m , λ is the wavelength of incident light given as 460 nm ,
Δy is the fringe width given as 3.90 nm
plugging these values into the equation, we have;
d = (1.86)(460 * 10^-9)/(3.9 * 10^-3)
d = 2.12 * 10^-4 m
Answer
given,
mass of crate = 32.5 Kg
horizontal force = 14 N
initial speed, u = 0 m/s
a) acceleration produced = ?
we know,
F = m a
a = 0.431 m/s²
b) using equation of motion
t = 10 s
s = 21.54 m
c) again using equation of motion
v = u + at
v = 0 + 0.431 x 10
v = 4.31 m/s
Explanation:
P = F/A
P = mg/A [ since F = mg ]
P = Vdg/A [ since m = Vd ]
P = Ahdg/A [ since V = Ah ]
P = hdg
Answer:
Dy = - 0.0789 [m]
Explanation:
The vertical component of the vector can be determined with the sine of the angle.
Dy = 0.250*sin(18.4)
Dy = 0.0789 [m]
As the y-component is pointing downwards the component is negative.
Dy = - 0.0789 [m]
PE stands for Potential Energy. It is the stored energy in an object due to its position with respect to some reference. It is expressed in Joules.
P.E = m * g * h OR P.E. = mgh
m - mass of the body
g - acceleration due to gravity
h - height attained due to the body's displacement.
K.E. stands for Kinetic Energy. It is the energy possessed by a body due to its motion.
K.E = 1/2 mv² where m = mass of the body; v = velocity with which the body is moving.
