What's a small fragments of matter (not asteroids) orbiting the sun?
Ymorist [56]

Answer:

Meteoroids

Explanation:

Meteoroids are small masses of rocks or metallic bodies that often found to orbit around the Sun. The size of a meteoroid is smaller in comparison to the asteroids. The elements that are found in the meteoroids are extraterrestrial nickel and iron. Meteoroids are often formed by the fragments from bodies present in universe such as Mars or Moon and thrown into space by an impact. After formation they often come in the range of attraction of Sun and start orbiting around it.

Which factor limits interference between waves? A constant phase relationship between waves Similar wave amplitudes Unequal wave
Alisiya [41]

Answer:

similar wave amplitudes

Explanation:

When two waves travelling in the same medium have similar wave amplitudes they are less likely to interfere with each other destructively or constructively because the interference between waves occur when the amplitudes of the waves arrive a position in the medium in opposite directions hence they add up( superposition) or cancel each other out.

Hence if the waves have similar wave amplitudes the interference between the waves will be limited.

A 0.05-m3 rigid tank initially contains refrigerant-134a at 0.8 MPa and 100 percent quality. The tank is connected by a valve to
lesya692 [45]

Answer:

A= 203 KJ

B= 54 Kg

Explanation:

The initial specific volumes and internal energies are obtained from A-12 for a given pressure and state. The enthalpy of the refrigerant in the supply line is determined using the saturated liquid approximation for the given temperature with data from A-11. The mass that has entered the tank is:

Δm = m₂ – m₁

= V(1/α₂ – 1/α₁)

= 0.05 (1/0.0008935 – 1/ 0.025645)Kg

= 54Kg

The heat transfer is obtained from the energy balance:

ΔU= m_i_n h_i_n+  Q_n_e_t

m₂u₂ – m₁u₂ = m_i_nh_i_n + Q_n_e_t

Q_n_e_t= m₂u₂ – m₁u₁ – m_i_n

= V/α₂u₂ - V/α₁u₁ – m_i_n

=(0.05/0.0008935 . 116.72 – 0.05/0.025645 . 246.82 – 54.108.28) Kj

= 203 KJ
