It may be an engine cooler, or it may be for the boats speed
But I think it is for cooling the engine down
The answer would be 23 because the engines in a horse is a amount of 9 engines in 69 cars
Answer:
stainless steel
Explanation:
Conductivity refers to the degree to which a specified material conducts electricity. It is the ratio of the current density in the material and the electric field.
The thermal conductivity of a material measures its ability to conduct heat.
In materials of low thermal conductivity, heat transfer occurs at a lower rate as compared to materials of high thermal conductivity.
Thermal expansion of the material refers to its tendency to change its shape, area, and volume as a result of change in temperature.
The electrical resistance of a material refers to the measure of its opposition to the flow of electric current.
<u>Stainless steel</u> has a lower coefficient of thermal conductivity along with a higher coefficient of thermal expansion and higher electrical resistance.
Answer:
3.25 ft/s
Explanation:
The crate is of =14-lb=m₁
The angle of inclination is = 40°=Ф
The initial velocity = 0.4 ft/s= v₁
Distance the crate will move is= 0.3 ft =d
The load pulling downwards is = 36 lb= m₂
Acceleration of the pulley, a= m₂g - m₁gsinФ / m₁+m₂ where g= 32.17 ft/s^2
a= 36*32.17 - 14*32.17*sin 40° / 14+36
a=17.37 ft/s^2
Apply the formula for final velocity
V₂²=V₁²+2ad
V₂²=0.4²+ 2*17.37*0.3
V₂²=10.582
V₂ =√10.582 = 3.25 ft/s
