Answer:
3.28 degree
Explanation:
We are given that
Distance between the ruled lines on a diffraction grating, d=1900nm=
Where
We have to find the angular width of the gap between the first order spectrum and the second order spectrum.
We know that
Using the formula
m=1
Now, m=2
Hence, the angular width of the gap between the first order spectrum and the second order spectrum=3.28 degree
A. The horizontal velocity is
vx = dx/dt = π - 4πsin (4πt + π/2)
vx = π - 4π sin (0 + π/2)
vx = π - 4π (1)
vx = -3π
b. vy = 4π cos (4πt + π/2)
vy = 0
c. m = sin(4πt + π/2) / [<span>πt + cos(4πt + π/2)]
d. m = </span>sin(4π/6 + π/2) / [π/6 + cos(4π/6 + π/2)]
e. t = -1.0
f. t = -0.35
g. Solve for t
vx = π - 4πsin (4πt + π/2) = 0
Then substitute back to solve for vxmax
h. Solve for t
vy = 4π cos (4πt + π/2) = 0
The substitute back to solve for vymax
i. s(t) = [<span>x(t)^2 + y</span>(t)^2]^(1/2)
h. s'(t) = d [x(t)^2 + y(t)^2]^(1/2) / dt
k and l. Solve for the values of t
d [x(t)^2 + y(t)^2]^(1/2) / dt = 0
And substitute to determine the maximum and minimum speeds.
(C)150 J, because the initial and final energy must be the same in an isolated system
Oh yea.. the Law of Conservation of energy states that energy stays the same throughout a system XD bet

hope this helps? :))
Answer:
2 N/m²
Explanation:
Pressure is defined as the force acting on a unit area .
Therefore;
Pressure = Force /Area
Force = 4 N
Area = 2 m²
Therefore;
Pressure = 4 N/ 2m²
= 2 N/m²
