Han emperors made ________ the official belief system of the state
Distance, Force
<u>Explanation:</u>
1) Increasing the load will add to the friction on the bearings of the pulleys, thus reducing the efficiency of the system. The ideal mechanical advantage won't change since the ideal mechanical advantage ignores friction.
2) Increasing the number of pulleys will increase the ideal mechanical advantage, but because of friction it will decrease the efficiency. The more pulleys that are turning, the more friction there is, and the less efficient the system will be.
3) Work = force x distance, and what machines do is alter the amount of force you can apply while at the same time reducing the distance moved by the same factor. For instance, a jack multiplies the force you apply by a factor of 100, when you push down on the handle of the jack 100 cm, the car will only go up 1 cm. So the force x distance is the same 100 x force x 1/100 x distance.
Answer:
Explanation:
The linear charge density id defined as the charge per unit length.
Let q be the charge and L be the length of the wire.
So, the linear charge density is
λ = q / L
If the length is 12 times, then charge should also be 12 times to keep the linear charge density same.
Answer:
1.False
2.4 E
Explanation:
1.We have to find the statement is true or false.
We know that
Time constant,
Time constant is inversely proportional to resistance R .It means when R increases then time constant decreases when R decrease then the time constant decreases.
Statement:The larger the value of R ,the longer it takes the circuit to reach its final steady- state value
It is false.
2.Energy stored in inductor,E=
When I'=2I
Then, 
Hence,the new total energy will become 4 E.
My estimate of brightness,
Number of batteries on a scale of 1 to 10
1 very dim
2 1
3 1 and 1/2
4 6
5 10 for a second, then
the bulb burned out
and changed to zero.
