Answer:
twelve facesFrom left to right the solids are tetrahedron (four sides), cube (six sides), octahedron (eight faces), dodecahedron (twelve faces), and icosahedron (twenty faces).
Explanation:
Ayo hope you enjoy
Explanation:
acc is velocity over time and the velocity rule is distance over time ..so acc would be distance over time power2
Answer with Explanation:
We are given that
a.Length of segment,l=20 m
Magnetic force ,F=
Substitute the values
Hence, the magnetic force exert by each segment on the other=0.0119 N
b.We know that when current carrying in the wires are in same direction then the force will attract to each other.
Hence, the force will be attractive.
Answer:
between 10 and 15 percent
Explanation:
How to put your load
- First load the heavy
The safe trailer starts loading correctly. Uneven weight can affect steering, brakes and swing control.
In general, 60% of the weight of the load should be in the front half of the trailer and 40% in the rear half (unless the manufacturer indicates something different). When you place the load, you want it to be balanced from side to side, keeping the center of gravity near the ground and on the axle of the trailer.
- Hold your load
After balancing the load, you must hold it in place. An untapped load can move when the vehicle is moving and cause trailer instability.
- Trailer weight
To avoid overloading the trailer, look for the recommended weight rating. It is located on the VIN plate in the trailer chassis, usually on the tongue. Confirm the Gross Vehicle Weight Classification (GVWR) before towing.
GVWR: is the total weight that the trailer can support, including its weight. You can also find this number as the Gross Trailer Weight (GTW). The weight of the tongue should be 10-15% of the GTW.
If the observer and the source are getting closer together OR getting farther apart, the observer will hear a sound with a different frequency compared to the sound that's actually coming out of the source.
An Austrian physicist and mathematician named Christian Doppler studied this effect, and he worked out the math that tells how much the frequency will change, depending on how fast the source and observer are moving, and whether they're moving together or apart.
After Doppler worked it out other scientists debated and argued for several years what they wanted to CALL this effect.
Some wanted to call it the "Freaky-Shifty Effect", because when the motion is there, the frequency of the source gets shifted.
Other scientists noticed that if the observer moves back and forth and back and forth, the frequency he hears goes up and down and up and down, and it sounds something like "OOWAH-EEYOO OOWAH-EEYOO", so THEY wanted to call it the "Y-U Effect".
After years of disagreement and debate, the cooler scientists found the best way to displease everyone. They just pointed out that it was Doppler who explained the whole thing and worked out all the math, and it would actually be nice to give him some credit for it. So everybody just cooled off and agreed to call it the <em>Doppler Effect</em> .
