Answer:
Explanation:
(a)
Applying the conservation of energy for cube,
i.e the initial kinetic energy of the body = its final potential energy
1/2mv² = mgh
h1 = v²/2g -------------------- (1)
and For cylinder,
the initial kinetic and rotational energy equals the final potential energy
1/2 mv² + 1/2 Iω² = mgh
here I = momentum of inertia of the cylinder
I = 1/2 m R²
∴ 1/2 mv² + 1/2 (1/2mR²)v²/R² = mgh
1/2 mv² + 1/4mv² = mgh
h2 = 3v²/4g -------------- (2)
From equations (1)&(2);
therefore the cylinder will go the greater distance up the incline.
(b)
h1-h2 = v²/2g - 3v²/4g
= 0.25 v²/g
the difference between the maximum distances the objects travel up the incline is 0.25*v²/g.
(c)
here we are taking into account of rotational energy.
Answer:
Explanation:
separation between slit d = 1.2 x 10⁻⁴ m
distance of screed D = 3.5 m
distance of second order right fringe
= 2λD / d where λ is wavelength of light .
2λD / d = .0375
2 x λ x 3.5 / 1.2 x 10⁻⁴ = .0375
λ = 6428 x 10⁻¹⁰ m
= 643 nm .
It’s says that the temperature in the room is 23C so the air temperature in the air would be 23C
