The correct answer is:
= g
Explanation:
When the object leaves the hand it has a force acted on it mainly it’s weight.
Answer:

Explanation:
Given:
- change in stiffness constant of the spring on replacing the original springs,

- mass of the car,

- initial length of the original car-spring before compression,

- final length of the original car-spring after compression,

So, weight of the car:



<u>Now the spring constant of original spring:</u>
(since 4 springs are in parallel)


<u>So the stiffness constant of the new springs:</u>



<u>Now the height lowered:</u>
(since 4 springs are in parallel)

Answer:
ΔS = 3.09 J/K
Explanation:
Entropy is defined as the magnitude of disorder in a system. Mathematically, entropy change is given as, the heat absorbed or released by a system divided by the change in absolute temperature. So, the formula for entropy change is as follows:
ΔS = ΔQ/ΔT
where,
ΔS = Change in Entropy of Metal Wire = ?
ΔQ = Heat Conducted through Wire = 1216 J
ΔT = Difference in Temperature = 686 K - 292 K = 394 K
Therefore,
ΔS = 1216 J/394 K
<u>ΔS = 3.09 J/K</u>
Answer:
yes. everything around you is matter including you!
Answer:
Explanation:
a_c = ω²R
14 rev/min (2π rad/rev)(1 min/60 s) = 1.466 rad/s
a_c = 1.466²(0.27/2)
a_c = 0.29 m/s²
