The spring constant of the spring if it would compress by 1 m to stop the ore car is 340,350.4 N/m.
<h3>
Potential energy of the car</h3>
The potential energy of the car is calculated as follows;
P.E = mgh
where;
- h is the vertical height of the incline
sin (10) = h/L
h = L x sin(10)
P.E = mgLsin(10)
P.E = 2000 x 9.8 x 50 x sin(10)
P.E = 170,175.21
<h3>Conservation of energy</h3>
The potential energy of the car at the top of the incline will be converted to the elastic potential energy spring at the bottom of the incline.
P.E = U = ¹/₂kx²
k = (2U)/x²
k = (2 x 170,175.2)/(1)²
k = 340,350.4 N/m

Explanation:
The equation of grating is given by :
Here,
(a+b) is called grating element
N is the number of slits per unit length,
n is the order
is the wavelength of light used
is the diffraction angle
Here, we need to write the effect on the interference pattern produced by a grating if the number of slits per unit length is increased. If the number of slits per unit length increases, the grating element decreases such that the angle of diffraction increases. Hence, the interference pattern shrinks.
Answer:
As they travel through rock, the waves move tiny rock particles back and forth -- pushing them apart and then back together -- in line with the direction the wave is traveling. These waves typically arrive at the surface as an abrupt thud. Secondary waves (also called shear waves, or S waves) are another type of body wave
