Compressions and refractions
opt.1
Answer:
answer is 2nd and 4th
Explanation:
heat always travels from higher amount to lower amount to make it equal or u can say to make the temperature equal the heat flows from higher temperature to lower temperature to make both the temperatures equal in 2nd and 4th option this process occurs because ice cubes have less amount of heat(temperature) than water and the air too have higher(temperature) amount of heat than ice and in 1st and 3rd option this exactly opposite of this process occurs which is not possible so ans is 2nd and 4th
Answer:
14.1seconds approx
Explanation:
Given data
Distance= 59.1m
Your velocity= 2.35m/s
Walkway velocity= 1.85m/s
Total velocity= 2.35+1.85= 4.2m/s
We know that
Velocity= distance/time
time= distance/velocity
substitute
time= 59.1/4.2
time= 14.07
time=14.1seconds approx
Hence the time is 14.1seconds approx
