Answer: industrial properties
Explanation:
The power plant listed by the agent falls under industrial property. An industria property is a property which is either used in manufacturing, rentage, warehousing, processing e.t.c.
in this case the plant Would be used in the generation of power which would be sold. so yes the property falls under the category
Answer:
a) v2f = 1.2 m/s, b) h = 7.35 10⁻² m and c) ΔK = -4196.4 J
,
Explanation:
a) This problem must be solved with the conservation of the moment. Let's define the system as the one formed by the bullet plus the block, in this system all the forces are internal therefore the moment conserves, let's write the moment in two moments before and after the crash. In general these shocks are very fast, so it can be assumed that the box does not move during the crash.
The data they give us is the mass of the bullet (m = 0.010 kg), the initial and final velocities of the bullet (v1o = 1000 m / s and v1f = 400 m / s) and the block gives us the mass M = 5 kg and its initial velocity v2o = 0 m / s
Before the crash
po = m v₁₀
After the crash
pf = m + M
p₀ = pf
m v₁₀ = m + M
v2f = m (v₁₀ - ) / M
v2f = 0.010 (1000-400) / 5
v2f = 1.2 m / s
b) Having the speed of the block we can use the law of conservation of energy to find the height. Let's write the mechanical energy of the block just after the crash and at the point of maximum height
Initial. Just after the crash
v =
Em1 = K = ½ M v²
Final. At maximum height
Em₂ = U = M g h
Em₁ = Em₂
½ M v² = M g h
h = ½ v² / g
h = ½ 1.2² / 9.8
h = 0.0735 m
h = 7.35 10⁻² m
c) Let's calculate the kinetic energy before and after the crash
Before
K₀ = ½ m v₁₀²
K₀ = ½ 0.01 1000²
K₀ = 5000 J
Final
= ½ m v1f² + ½ M v2f²
= ½ 0.010 400² + ½ 5 1.2²
= 800 + 3.6
= 803.6 J
We can give the amount of energy that is lost as the subtraction of the two energies or as the fraction of lost engoa
ΔK = -K₀
ΔK = 803.6 - 5000
ΔK = -4196.4 J
/ K₀ = 803.6 / 5000
/ K₀ = 0.16
Answer:
2.538 liters of mercury inside each flask
Explanation:
Let the mercury density be 13593 kg per cubic meters. The volume of the mercury contained in flasks that weight 34.5 kg each would be its mass divided by the density
V = 34.5 / 13593 = 0.002538 cubic meter or 2.538 liters
Answer:
elliptical orbit
Explanation:
There are three laws of planetary motion, which are called Kepler's law of planetary motion.
First Law : It states that all the planets revolve around the sun in an elliptical path and the sun is at one focus of that elliptical path.
