Gnom [1K]

Answer:

356K

Explanation:

use this formula for brayton cycle

∩=1-(Tin/Tout)

where

∩=efficiency

Tin=  inlet temperature

Tout= outlet temperature

solving

Tout=Tin/(1-∩)

Tout=267K/(1-0.25)

Tout=356K

Illusion [34]
<span>We can use the equation for the force of gravity to solve this question. F = G M1 M2 / R^2 Let R be the radius of the planet. f0 = G M1 M2 / (2R)^2 f0 = (1/4) x (G M1 M2 / R^2) We can find an expression for f2. f2 = G M1 M2 / (4R)^2 f2 = (1/16) x (G M1 M2 / R^2) We can express f2 in terms of f0: f2 = (4/16) x f0 f2 = 0.25 f0</span>

similar to the case in the experiment you use two rubber bands, side to side first, to hold a weight of 3 reference objects. the
Sever21 [200]

Three units deformations observed in these bands.

<h3>What forces do a rubber band encounter?</h3>

Elastic force is the force that permits some materials to regain their former shape after being stretched or crushed. Thus, a stretched rubber band is subject to an elastic force.

The rubber band experiment uses a straightforward rubber band to show entropic force and a refrigeration cycle. The rubber band experiment involves stretching and then releasing a rubber band while measuring its temperature.

Always acting in the opposite direction of motion is friction. This indicates that if friction is there, it cancels out some of the force driving the motion (if the object is being accelerated). This results in a decreased acceleration and a smaller net force.
