When a wave enters a new medium slows down and bends the wave undergoes what?
Diffraction, with light it splits the colors most notably in a prism.
What are 3 facts about friction?
1) friction thats lows things down is called dynamic friction 2) friction that stops things is called static friction 3) most of friction makes heat ( rubbing hands together )
WhaT are the 3 most important forces in physical science Fforces in physical science?
gravity,potential force,and force
Force can be calculated as pressure x area Which of the following will produce the most force?
10 p over 10 m2
Is friction useful for ships?
Yes and no. In order to go faster, a ship must reduce its air and water friction as much as possible, as friction force acts in the opposite direction as motion, ie slows the object down. However, it is friction that allows the propulsion system to 'push' the ship forward. This deals more with viscosity, which is *like* the friction of a liquid. In sailboats, it is the friction with the air that propels the ship.Because friction is related to the area of contact and the vector of the velocity, it is ideal to have the least amount of surface area facing to the direction of motion, which is why most ships have a Vshape in the front.
With age for most people the ability to absorb new information speeds up slows down?
SLOWS
What a moving object in outer space slow down?
Most objects in outer space are moving under the gravitational attraction of other galaxies or galactic clusters. The attractive force speeds them up rather than slows them down.
What non opaque substance slows down light the most?
water [No; it's not water.]
When a person stops pedaling the bicycle slows down what force is this?
air Resistance is proportionate to velocity squared, so air resistance is dominant over a certain speed, but below that speed it will be rolling resistance that is the biggest factor. At 12mph, 80% of your effort goes into overcoming air resistance on a cycle.
The process in which sedimentary material slows down or from ice that melts?
The process in which moving sedimentary material slows down or from ice that melts is known as deposition. Most metamorphic sedimentary rocks are formed through this process.

Why does ford transit slows down and blow white smoke?
Most likely it is the head gasket bad. If the exhaust has a sweet smell to it, that is anti freeze getting into the cylinder. It slows down because 1 or 2 of the cylinders are not firing.
What three things can happen to an object if the forces acting on it are unabalanced?
it will become unballanced it will push the side that has the most force on it down it will become unstable
When an object slows down does it have acceleration?
yes, but its value is negative ( as in -x m/s¨2). However it is most often noted as deceleration.
Which is the most advance force in the US military?
Advanced how? Technologically, the Navy and Air Force have this, hands down.
What if your snowmobile that stalls when slows down What is wrong with it?
Could be clutches or fuel. Make sure carbs are clean. Most problems come from dirty carbs.
What happens during the eighth month of pregnancy?
Growth continues but slows down as the baby begins to take up most of the room inside the uterus.
