Answer:
273 Kelvin
Explanation:
If -273 Celsius is 0 Kelvin, then 273 Kelvin will be 0 Celsius.
Speed is constant. 50 miles = 1 hour. 600/50 = 12. 1hr(12) = 12 hours.
Answer: Option (C)
Explanation: Rock cycle plays an important role in the alteration of rocks from one form to another.
- Igneous rocks when undergoes high temperature and pressure condition, it transforms into a metamorphic rock.
- Sedimentary rocks are formed from the sedimentation and consolidation of sediments
- Igneous rocks are formed due to the crystallization of magma.
Hence the correct answer is option (C)

Answer:
50 N
Explanation:
Let the force in the horizontal rope be F₁ and the force in the diagonal rope be F₂:
The total force in the horizontal and vertical directions must be zero, since the object is at rest and is not accelerating.
The horizontal component of the forces:
F₁ + F₂ = -40N + F₂ = 0
F₂ = 40N
The vertical component of the forces:
F₁ + F₂ - mg = 0 + F₂ - mg = 0
F₂ = mg
If I assume the gravitational constant g = 10 m/s²:
F₂ = (3 kg) * (10 m/s²) = 30N
Adding the horizontal and vertical components of the force F₂:
F₂ = √((40N)² + (30N)²) = 50N
