Sound waves produced by a vibrating object are _____.

Answer: 1) Sound waves produced by a vibrating object are compressional waves. The reason being that the matter in the medium moves back and forth in the same direction that it travels. 2) Loudness is the human perception of sound wave intensity. 3) The process of detecting objects by bouncing sounds off them is called echolocation. It is also called bio sonar and animals like bats use it to detect objects near them.

I hope it helps, Regards.

Calculate the value of ∆g for these initial partial pressures. (the partial pressure of each gas is set a 5. 0 atm at 25°c) (use
Sati [7]

∆g for these initial partial pressures is 10,403.31 KJ.

   

ΔG gets increasingly positive as a product gas's partial pressure is raised. ΔG becomes more negative as the partial pressure of a reactant gas increases.

                                  ∆g = RT ln (q/k)

In this equation: R = 8.314 J mol⁻¹ K⁻¹ or 0.008314 kJ mol⁻¹ K⁻¹

                            K = 325

If ΔG < 0, then K > Q, and the reaction must proceed to the right to reach equilibrium.

∴∆g = RT ln (q/k)

        = 8.314 × 298 ln ( 5 / 325)

        = 2477.57 ln 0.015

        = 2477.57 × (-4.199)

        = 10,403.31 KJ

Products are preferred over reactants at equilibrium if G° 0 and both the products and reactants are in their standard states. When reactants are preferred above products in equilibrium, however, if G° > 0, K 1. At equilibrium, neither reactants nor products are preferred if G° = 0, hence K = 1.

Therefore, ∆g for these initial partial pressures is 10,403.31 KJ.

A projectile is fired at an upward angle of 29.7° from the top of a 108-m-high cliff with a speed of 130-m/s. What will be its
german

Answer:

79.2 m/s

Explanation:

θ = angle at which projectile is launched = 29.7 deg

a = initial speed of launch = 130 m/s

Consider the motion along the vertical direction

v₀ = initial velocity along the vertical direction = a Sinθ = 130 Sin29.7 = 64.4 m/s

y = vertical displacement = - 108 m

a = acceleration = - 9.8 m/s²

v = final speed as it strikes the ground

Using the kinematics equation

v² = v₀² + 2 a y

v² = 64.4² + 2 (-9.8) (-108)

v = 79.2 m/s
