Answer:
the water will boil and change into a gas
Explanation:
This is because it is exothermic and releases the energy into the surroundings and the fact that water boils at 100 degrees Celsius
Answer:
55 ft/s
Explanation:
A₁ = Area of rectangular cross-section at input side = 1.5 x 11 = 16.5 ft²
A₂ = Area of rectangular cross-section at far end = 1.5 x 6 = 9 ft²
v₁ = speed of water at the input side of channel = 30 ft/s
v₂ = speed of water at the input side of channel = ?
Using equation of continuity
A₁ v₁ = A₂ v₂
(16.5) (30) = (9) v₂
v₂ = 55 ft/s
As we've seen, the exhaust speed in part (a) was 2000 m/s, and the exhaust speed in part (b) was 5,000 m/s, which is obviously 2.50 times faster than in part (a). However, there is no relationship between the beginning and end fuel mass. The necessary fuel mass is not just less by a factor of 2.50 since the initial and final fuel masses really have a logarithmic relationship rather than a simple linear one.
<h3 /><h3>What is exhaust speed?</h3>
The exhaust speed is the difference between the rocket speed and the propellant speed. The exhaust speed of the best chemical rockets is close to 3,000 meters per second. Exhaust speeds while using electric propulsion can reach 20,000 meters per second or greater.

False! Because it turns from weight to mass
