A tea kettle is boiling on the stove, and all of a sudden the whistle in the spout of the kettle starts shrieking. Steam rising from the boiling water causes the whistle to sound. What part of the water cycle does the steam represent
Answer:
Condensation is your answer
Explanation:
Condensation is the process of steam rising back into the atmosphere and the steam would be the evaporation "steam" hope this helped
Steam rising from the boiling water causes the whistle sound, which means that the convection part of the water cycle is present here.
What is convection?The process of convection entails the movement of a heated fluid, such as air or water, in order to transfer heat.
Convection is caused by the fact that most fluids have a tendency to expand when heated, which causes them to become less dense and rise due to the increased buoyancy. The homogeneous heating of air in a heated room or water in a kettle is due to circulation generated by this effect: heated particles expand the area they move in by moving faster against each other, rise, and afterwards cool and close again, increasing density and causing a corresponding sinking.
In forced convection, fluid is carried using mechanisms other than those that result from differences in density with temperature. Examples of forced convection include the air movement by a fan or water by a pump.

If a load of 600 N is overcome by a simple machine using an effort of 400 N. Calculate the mechanical advantage.
ㅤ➙ Mechanical Advantage= 1.5
Solution:Mechanical advantage allow to perform tasks much easier in terms of the force needed to apply, but must always obey the conservation of energy. Mechanical advantage is the measure of the ratio of output force to input force needed in a system, used to analysis the force in simple machines like livers and pulleys.
Mechanical advantage is given by:
[tex] \qquad\hookrightarrow\quad {\pmb{\sf{MA =\dfrac{Load}{effort} }} }[/tex]
We are provided with:
Load = 600 NEffort = 400 NTherefore,
[tex] :\implies\quad \sf{MA = \dfrac{L}{E} }[/tex]
[tex] :\implies\quad \sf{ MA = \dfrac{6\cancel{00}}{4\cancel{00}}}[/tex]
[tex] :\implies\quad \sf{MA=\dfrac{6}{4} }[/tex]
[tex]: \implies\quad \sf{ MA =\dfrac{3}{2}}[/tex]

What does it mean if electric field lines are close together versus farther apart ?
Answer:
As a result, if the field lines are close together (that is, the field line density is greater), this indicates that the magnitude of the field is large at that point. If the field lines are far apart at the cross-section, this indicates the magnitude of the field is small. (Figure) shows the idea.

Define force as the cause of acceleration?
Physics
Answer:
In short, a force applied to an object at rest causes it to accelerate in the direction of the force.
Explanation:
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e. to change its velocity, at a constant rate.
Answer:
As the force acting upon an object is increased, the acceleration of the object is increased.
Explanation:
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

Answer:
v = 20 m/s
Explanation:
Let's use v = u + at for uniform acceleration.
v = finaly velocity
u = initial velocity
a = acceleration
t = time
Since we start from rest, our initial velocity is zero.
