Answer:
The position of the first dark spot on the positive side of the central maximum is 1.26 mm.
Explanation:
Given that,
Wavelength of light is 633 nm.
Slit width, d = 0.5 mm
The diffraction pattern forms on a screen 1 m away from the slit. We need to find the position of the first dark spot on the positive side of the central maximum.
For destructive interference :

Y is the distance of the minima from central maximum
Here, n = 1

So, the position of the first dark spot on the positive side of the central maximum is 1.26 mm.
The answer is convection. There are three main types of heat transfer: conduction, convection, and radiation. Among the three, convection is the one that involves heat transfer through a flowing material or medium. Conduction involves the direct contact between two surfaces at different temperatures, while radiation involves heat transfer through electromagnetic waves.
The kinetic energy of the crate as it reaches the lower surface is 80 J
Kinetic energy is the energy possed by an object in motion. Mathematically, the kinetic energy can be expressed as follow:
KE = ½mv²
With the above formula, the kinetic energy of the crate can be obtained as follow:
- Mass (m) = 10 Kg
- Velocity (v) = 4 m/s
- Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 10 × 4²
KE = 5 × 16
KE = 80 J
Therefore, the kinetic energy of the crate is 80 J
