Speed equals distance divided by time, so 350 divided by 2.5 equals 140 kilometers per hour.
Answer:
153.6 kN
Explanation:
The elastic constant k of the block is
k = E * A/l
k = 95*10^9 * 0.048*0.04/0.25 = 729.6 MN/m
0.12% of the original length is:
0.0012 * 0.25 m = 0.0003 m
Hooke's law:
F = x * k
Where x is the change in length
F = 0.0003 * 729.6*10^6 = 218.88 kN (maximum force admissible by deformation)
The compressive load will generate a stress of
σ = F / A
F = σ * A
F = 80*10^6 * 0.048 * 0.04 = 153.6 kN
The smallest admisible load is 153.6 kN

Answer:
He can figure out if they heat to the same temp with the thermometer.
Explanation:
They have different boiling points and heat up at different rates so they would have different temps at the same time
It causes a movement of convection in the water resulting in a pulling current.
Hope this helpss
