Why does the pet's water bowl overflow?

The reason may be simple, because your container not only has angular movement, initially T-2 tilts forward, then T-1 tilts backward, but also horizontal movement from right to left during this ...

Why does the pet's water bowl overflow?

If you check the tide chart for your local area you will find that the bowl overflows only during the incoming tide and is directly proportionate to what stage the tide is at when you set the bowl ...

Why does the pet's water bowl overflow?

The two horizontal sloshing modes could have slightly different frequencies (e.g. if the rotational symmetry is not perfect). If you then start with the combination of both, but out of phase, which is ...

Why does the pet's water bowl overflow?

If the mat is thick and soft enough to be compliant, then it will couple with the moving mass of the dish and water and allow the dish to tip back and forth, causing the spillage. This can be directly ...

Why does the pet's water bowl overflow?

A guess. Perhaps there are multiple modes present. It takes a while for them to have an interference maximum at the edge of the bowl.

How exactly does a seashell make the humming sound?

The question to the answer is: The seashell does not make noise. The answer to the question: What is the source of what you hear if you close your one ear with a cup and close the other ear competely ...

Why does bringing a helium filled latex balloon close to my ear make it feel pressurized?

I've wondered the same and came across an explanation that the helium may act as a lens & cause the sound waves to diverge. Definitely a noticeable phenomenon, I'm surprised there's no simple ...

Why does canola oil heat up in the microwave?

I'll try to add something to the excellent answers already posed, mainly in the work of Vieira and Regitano-D'arce about it. I'm afraid this is a chemistry problem, but I don't see a natural division ...

How exactly does a seashell make the humming sound?

Neither of the three explanations are true. Actually, the seashell amplifies and reflects the sound of your blood flowing through the blood vessels in your ear! That is what you hear as humming.

How small can a flame get?

The paper by Sunderland et al. (2011) discusses the characteristics and measurements of candle flame shapes, including an analysis of flame height and width for various wick diameters and lengths. It ...

Should I hold a baby formula bottle to cool it down faster?

Sure! I think I'm qualified to answer, not because I used to teach heat transfer in a Chemical Engineering course, but because I raised four daughters!! Air is an excellent thermal insulator. If you ...

Ice skating, how does it really work?

Your calculations are right, I think. I'm going to do the math here too and the pressure required is great. Your model, however, is wrong if you are imagining a piston compressing an ice cube. This is ...

How exactly does a seashell make the humming sound?

The shell with a small opening forms a Helmholtz resonator that is excited by noise from outside. Image from Formulas of Acoustics, F.P. Mechel pp72. The Wikipedia article has relevant equations for a ...

Should I hold a baby formula bottle to cool it down faster?

Liquid cooling is generally more efficient than air cooling for CPUs and car engines, even though a fan is used in the air cooling versions. In the case of the baby bottle we are not comparing the ...

How exactly does a seashell make the humming sound?

While inside your house, place a shell or a cup or a drinking glass or even a cupped hand over your ear and you will observe the same phenomena. Assuming there is no significant wind inside your house ...

How exactly does a seashell make the humming sound?

Your third option is the closest to the case. The seashell forms a cavity resonator, which will have some characteristic frequency response determined by things like the shape of the shell etc. ...

Should I hold a baby formula bottle to cool it down faster?

No. Holding bottle is not the best way to cool it down faster. I would suggest you to keep the cover of bottle open and also keep stirring bottle slowly to let the heat escape. Stirring will cool it ...

Should I hold a baby formula bottle to cool it down faster?

Obviously at constant thermal conductivity you would want to keep the bottle in contact with the cooler bath, the air, rather than the warmer bath, your hand. So air has the advantage that it is ...

How does a vehicle's brake affect the friction between the vehicle and ground?

Kinetic friction is when one object slides over another - in this case, it's either the tire skidding on the road or the brake calipers gently gripping but not stopping the rotor (braking surface). ...

How does a vehicle's brake affect the friction between the vehicle and ground?

So does braking affects the friction? Does it increase the coefficient of friction? The short answer to the first question is yes. The static friction increases. This is not the same as saying the ...

How does a vehicle's brake affect the friction between the vehicle and ground?

It is true that both brake and wheel-ground systems work based on friction. However, these frictions are not the same. Let us look at them separately. Brake system. In the brake system, friction is ...

How does a vehicle's brake affect the friction between the vehicle and ground?

Initially when the vehicle is moving with a constant velocity, there is no relative velocity between the point of contact of tire and the ground. When there is no relative velocity between the tire ...

How does a vehicle's brake affect the friction between the vehicle and ground?

Friction coefficient is a function of the material and the condition (wear, wet,...) of wheel surface and ground. So, while braking without slip, friction coefficient is approximately constant. What ...
