Answer:
The height of the mountain is 4670.35 metres.
Explanation:
Answer:
464.373 ft / s, 43200 ft/s²
Explanation:
200 mi/h = 293.333 ft/s
3 mi/h² = 3 × (1 ft / s² / 2454.5454) = 0.0012222 = acceleration of the airplane
velocity of the rotating propeller Vr = ωr where ω is the angular rate = 120 rad/s and the radius = 6 ft /2 = 3 ft = 120 × 3 = 360 ft / s
Velocity of the particle = resultant of the velocities = √ ( 293.333² + 360² ) = 464.373 ft / s
centripetal acceleration = Vr² / r = 360² / 3 = 43200 ft/s²
acceleration of the particle = resultant accelerations = √ ( 0.001222² + 43200²) = 43200 ft/s²

Answer: Equilibrium temperature they reach is 383 K
Explanation:
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of gold = 1.3 kg
= mass of copper = 2.1 kg
= final temperature = ?
= temperature of gold= 300 K
= temperature of copper = 400 K
= specific heat of gold =
= specific heat of copper =
Now put all the given values in equation (1), we get
Thus equilibrium temperature they reach is 383 K
