<h2>You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy.</h2><h2>Hope it helps..</h2>
Answer:
2.14 kW, I₂ < I₁
Explanation:
The three resistors are in parallel. The net resistance is:
1/R = 1/R₁ + 1/R₂ + 1/R₃
1/R = 1/20 + 1/8 + 1/500
1/R = 0.177
R = 5.65
The power is:
P = IV
P = (V/R) V
P = V²/R
P = (110)² / 5.65
P = 2140 W
P = 2.14 kW
For two resistors in parallel, the one with the higher resistance has the smaller current. I₂ < I₁.
Answer:
Explanation:
Spring constant is given as:
But F is mass times velocity(gravitational acceleration=
83N/m=
Therefore the ruler reading will be . Hence the ruler reading is 0.4451m
This is a conversion problem. 760 Torr is equal to 1 atmosphere. so we can can solve now. 5,550torr*(1atmosphere/760torr)=7.3atmospheres. since the two torrs cancel out with cross multiplication we are left in atmosphere units.
