The answer is C. Mountains. I hope this helped!
Because plastic and rubber are insulators.
Water holds in heat very well. Keep the temperature more steady and average. The areas around the water will also have a less variant change in temperature as a result. This property of water is known as high specific heat.
An ideal machine is one in which no part of the input energy to the machine gets wasted and the whole input energy is converted into the useful work. The <span>efficiency of such a machine is 100%.

The final speed of the combined masses is 0.21 m/s
Applying the law of conservation of momentum:
Total momentum before collision = Total momentum after collision.
⇒ Formula:
MU+mu = V(M+m).................. Equation 1
⇒ Where:
- M = mass of the first body
- m = mass of the second body
- U = Initial speed of the first body
- u = Initial speed of the second body
- V = common final speed.
From the question,
⇒ Given:
- M = 0.24 kg
- U = 0.60 m/s
- m = 0.26 kg
- u = -0.20 m/s (traveling in opposite direction)
⇒ Substitute these values into equation 1
- 0.24(0.6)+0.26(-0.20) = V(0.24+0.2)
⇒ Solve for V
- 0.144-0.052 = 0.44V
- 0.44V = 0.092
- V = 0.092/0.44
- V = 0.209
- V ≈ 0.21 m/s
Hence the final speed of the combined masses is 0.21 m/s
