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 :
Where, 
So, 50 degree Celsius is equal to 122 degree Fahrenheit. Hence, this is the required solution.
D. There is a known constant concentration of C14 in Nature. As we consume living things to survive our bodies (made of carbon) stop replenishing our body's carbon (we stop eating) and start to decay. Since we know the 1/2 life of C14 and the ratio of C14 to normal C12 we can determine fairly accurately how long ago a thing stopped consuming carbon (e.g. when it died)
Answer:
Explanation:
In Carnot engine , temperature difference is used to get work output .
The maximum efficiency of a Carnot engine
= (T₁ - T₂) / T₁
where T₁ is temperature of hot reservoir , and T₂ is temperature of cold reservoir
= efficiency = ( 35 - 4 ) / ( 273 + 35 )
= 31 / 308
in percentage terms
efficiency = (31 / 308) x 100
= 10.06 % .
The first thing you should know is that the friction force is equal to the coefficient of friction due to normal force.
Therefore, clearing the normal force we have:
The friction is 565N.
(565 / 0.8) = 706.25N. weight.
