A car slowing as it reaches a traffic light, because it is the only option with acceleration/ deceleration.
And forces require the mass of the object AND the acceleration.
Answer:
The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to solid.
Explanation:
The conversion of water to ice is a phase change from liquid to solid. There is no chemical action taking place in this process just the state of matter taking up a new form.
- This phase change is called freezing.
- In freezing, the liquid water loses energy to the surroundings.
- By so doing, the water molecules have lesser energy
- The then take up fixed position within the lattice.
- This changes the state to solid with a well - ordered arrangement.
refraction is the right answer
To get it to start moving, he have to exert a force equal to its maximum force of static friction.
F= fs,max = Ms m g= (0.21) * (180) * (9.8) = 370 N
Let me know if im wrong but if not brainliest user for helping or best answer
Answer:
The ratio between W2 and W1 is
p=1.5
Explanation:
The W2/W1 ratio equals the efficiency ratio, since the heat input is constant.
Initially, the Carnot efficiency is
1 - (Tc/Th)
1 - 400/800 = 0.50
After lowering Tc, the efficiency becomes
1 - (Tc/Th)
1 - 200/800 = 0.75
So to determine the ratio between W2 and W1
W2/W1 = 0.75/0.50 = 1.5
