Sorry this might not be great but when the air is cold the molecules are dense which means they are much closer together and hit each other but when they air is hot the molecules aren’t as dense which means they are more spread out. so as the cold air molecules are closer together, more of them could fit inside the balloon but with hot air since the molecules are so far apart not as many can fit in as they take up more as they spread and hit the side of the balloon
(h + .16) m g = 1/2 k x^2 total PE of block relative to where it stops
(h + .16) .82 * 9.8 = .5 * 120 * .16^2 PE released = PE of spring
8.04 h + 1.29 = 1.536
h = (1.536 - 1.29) / 8.04 = .031 m = 3.1 cm
10 newton east is the answer because the two force vector form 0 degree angle with each other
Answer:
Design 2
Explanation:
I had this same question
My answer:
"Design 2 is the well-designed one, because the air molecules are the most compact and could protect the individual better than 1,3,and no air bag."
Answer:
3.69 V
Explanation:
By connecting across the resistor, the capacitor starts discharging.
The voltage across the capacitor when discharging is given by
V is the voltage across it at time t,
is the initial voltage when fully charged,
T is the time constant
After one time constant, t = T. Then
From the question,
