Answer:
⇒ 401.6 ± 7.1 ms
⇒ 57.2 ± 1.6 kg
⇒ 8.1 × 107 ± 2.9 × 105 m
⇒ 2.1 ± 8.8 µN
⇒ 294 ± 0.005 cm
Explanation:
As given all equation we do without calculation we will get here round these calculations which is given below as
a) 401.6473 ± 7.0912 ms
⇒ 401.6 ± 7.1 ms
b) 57.212 ± 1.612 kg
⇒ 57.2 ± 1.6 kg
c) 8.12754×107 ± 2.847×105 m
⇒ 8.1 × 107 ± 2.9 × 105 m
d) 2.94 ± 8.803 µN
⇒ 2.1 ± 8.8 µN
e) 294 ± 0.00481 cm
⇒ 294 ± 0.005 cm
Convection is transfer of heat between a solid and a moving fluid. Boiling or condensing processes are example for convection processes.
The formula for convection is:
<span>q = hc A dT</span>
where
<span>hc is convective heat transfer coefficient of the process (W/(m2K) or W/(m2oC <span>q
</span>A<span> is the heat transfer area of the surface (m2, ft2)
</span><span>hc </span><span>= convective heat transfer coefficient of the process (W/(m2K) or W/(m2oC), <span>Btu/(ft2 h oF)</span>)</span><span>q is heat transferred per unit time (W, Btu/hr)</span>dT is the <span>temperature difference between the surface and the bulk fluid (K or oC, F)</span>
</span>
Answer:
B. 17m/s
Explanation:
This question contains a graph that illustrates the relationship between the speed of a car over time. The graph shows that one can make an inference of the amount of time it takes for the car to cover a particular speed and vice versa.
In this case, after 3 seconds, the speed of the car will be 17 m/s. This inference was got by tracing the position of 3s in the x-axis to the value on the y-axis. Doing this, the best inference for the speed of the car after 3 seconds is 17m/s.
