Answer:

10 kJ

Explanation:

W = Fd

W = (μN)(vt)

W = μ(mg)vt

W = 0.7(42.9)(9.81)(9)(3.8)

W = 10,075.12506 J

W ≈ 10 kJ

50°C is equivalent to a 82 F b- 90"F c 122"F

andre [41]

Answer:

50°C = 122 Fahrenheit

Explanation:

Here, we need to convert 50°C to F i.e. Fahrenheit. The conversion formula from degree Celsius to Fahrenheit is as follows :

$^{\circ}F=(^{\circ}C\times \dfrac{9}{5})+32$

Where, $^{\circ}C=50^{\circ}C$

$^{\circ}F=(50\times \dfrac{9}{5})+32$

$^{\circ}F=122^{\circ} F$

So, 50 degree Celsius is equal to 122 degree Fahrenheit. Hence, this is the required solution.
